Subject: drm/sched: Fix a race in DRM_GPU_SCHED_STAT_NO_HANG test
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The "skip reset" test waits for the timeout handler to run for the
duration of 2 * MOCK_TIMEOUT, and because the mock scheduler opted to
remove the "skip reset" flag once it fires, this gives opportunity for the
timeout handler to run twice. Second time the job will be removed from the
mock scheduler job list and the drm_mock_sched_advance() call in the test
will fail.

Fix it by making the "don't reset" flag persist for the lifetime of the
job and add a new flag to verify that the code path had executed as
expected.

Subject: drm/v3d: Add parameter to retrieve the global number of GPU resets
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The GL extension KHR_robustness uses the number of global and per-context
GPU resets to learn about graphics resets that affect a GL context. This
commit introduces a new V3D parameter to retrieve the global number of
GPU resets that have happened since the driver was probed.

To retrieve this information, user-space must use DRM_V3D_PARAM_GLOBAL_RESET_COUNTER.

Subject: drm: Add DRM prime interface to reassign GEM handle
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CRIU restore of drm buffer objects requires the ability to create
or import a buffer object with a specific gem handle.

Add new drm ioctl DRM_IOCTL_GEM_CHANGE_HANDLE, which takes
the gem handle of an object and moves that object to a
specified new gem handle.

This ioctl needs to call drm_prime_remove_buf_handle,
but that function acquires the prime lock, which the ioctl
needs to hold for other purposes.

Make drm_prime_remove_buf_handle not acquire the prime lock,
and change its other caller to reflect this.

The rest of the kernel patches required to enable CRIU can be
found at
https://lore.kernel.org/dri-devel/20250617194536.538681-1-David.Francis@amd.com/

v2 - Move documentation to UAPI headers
v3 - Always return 0 on success

Subject: drm: Move drm_gem ioctl kerneldoc to uapi file
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The drm_gem ioctls were documented in internal file drm_gem.c
instead of uapi header drm.h. Move them there and change to
appropriate kerneldoc formatting.

Subject: drm/sched: Avoid double re-lock on the job free path
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently the job free work item will lock sched->job_list_lock first time
to see if there are any jobs, free a single job, and then lock again to
decide whether to re-queue itself if there are more finished jobs.

Since drm_sched_get_finished_job() already looks at the second job in the
queue we can simply add the signaled check and have it return the presence
of more jobs to be freed to the caller. That way the work item does not
have to lock the list again and repeat the signaled check.

Subject: drm/panthor: Fix memory leak in panthor_ioctl_group_create()

When bailing out due to group_priority_permit() failure, the queue_args
need to be freed. Fix it by rearranging the function to use the
goto-on-error pattern, such that the success case flows straight without
indentation while error cases jump forward to cleanup.

Subject: rust: drm: Drop the use of Opaque for ioctl arguments

With the Opaque<T>, the expectations are that Rust should not
make any assumptions on the layout or invariants of the wrapped
C types. That runs rather counter to ioctl arguments, which must
adhere to certain data-layout constraints. By using Opaque<T>,
ioctl handlers are forced to use unsafe code where none is actually
needed. This adds needless complexity and maintenance overhead,
brining no safety benefits.
Drop the use of Opaque for ioctl arguments as that is not the best
fit here.

Subject: drm/panel-edp: Add disable to 100ms for MNB601LS1-4

For the MNB601LS1-4 panel, the T9+T10 timing does not meet the
requirements of the specification, so disable is set to 100ms.

Subject: drm/bridge: select_bus_fmt_recursive(): put the bridge obtained by
 drm_bridge_get_prev_bridge()

The bridge returned by drm_bridge_get_prev_bridge() is refcounted. Put it
when done.

select_bus_fmt_recursive() has several return points, and ensuring
drm_bridge_put() is always called in the right place would be error-prone
(especially with future changes to the select_bus_fmt_recursive() code) and
make code uglier. Instead use a scope-based free, which is future-proof and
a lot cleaner.

Subject: drm/panel-edp: Add 50ms disable delay for four panels

Add 50ms disable delay for NV116WHM-N49, NV122WUM-N41, and MNC207QS1-1
to satisfy T9+T10 timing. Add 50ms disable delay for MNE007JA1-2
as well, since MNE007JA1-2 copies the timing of MNC207QS1-1.

Specifically, it should be noted that the MNE007JA1-2 panel was added
by someone who did not have the panel documentation, so they simply
copied the timing from the MNC207QS1-1 panel. Adding an extra 50 ms
of delay should be safe.

Subject: panthor: save task pid and comm in panthor_group

We would like to report them on gpu errors.

We choose to save the info on panthor_group_create rather than on
panthor_open because, when the two differ, we are more interested in the
task that created the group.

Subject: drm: Create mipi_dsi_dual* macros

Create mipi_dsi_dual, mipi_dsi_dual_dcs_write_seq_multi, and
mipi_dsi_dual_generic_write_seq_multi macros for panels which are driven
by two parallel serial interfaces. This allows for the reduction of code
duplication in drivers for these panels.

Remove mipi_dsi_dual_dcs_write_seq_multi definition from
panel-novatek-nt36523.c to avoid the duplicate definition. Make novatek
driver pass mipi_dsi_context struct as a pointer.

Subject: drm/panel: jdi-lpm102a188a: Fix bug and clean up driver

Fix bug in unprepare() which causes the function's return value to be
that of the last mipi "enter sleep mode" command.

Update driver to use the "multi" variant of MIPI functions in order to
facilitate improved error handling and remove the panel's dependency on
deprecated MIPI functions.

Use the new mipi_dsi_dual macro to reduce code duplication.

Subject: drm: bridge: Add support for Solomon SSD2825 RGB/DSI bridge

SSD2825 is a cost-effective MIPI Bridge Chip solution targeting mainly
smartphones. It can convert 24bit RGB interface into 4-lane MIPI-DSI
interface to drive display modules of up to 800 x 1366, while supporting
AMOLED, a-si LCD or LTPS panel technologies for smartphone applications.

Subject: drm/vkms: Add writeback encoders as possible clones
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since commit 41b4b11da0215 ("drm: Add valid clones check") setting
the `possible_clones` values is a hard requirement for cloning.
`vkms` supports cloning for writeback connectors in order to capture
CRTC content, however that broke with said commit.

Writeback connectors are created on a per-CRTC basis, thus mark
every non-writeback connector that is compatible with a given CRTC
as possible clone - and vice-versa.

Using a default configuration, the corresponding `drm_info` output
changes from:

Subject: drm/panel-edp: Add edp panels used by mt8189 Chromebooks

Add a few generic edp panels used by mt8189 chromebooks, most of
them use the same general enable timing 50ms. For BOE-NV116WHM-N4B and
BOE-NV116WHM-T01 CMN-N140JCA-ELP the enable timing required 80ms. For
CMN-N116BCA-EAK, the enable timing required 200ms and disable timing
required 50ms. For CMN-N116BCL-EAK and CMN-N122JCA-ENK the enable timing
required 80ms and disable timing required 50ms. For TMA-TL140VDMS03-01,
the enable timing required 50ms and the disable timing required 100ms.

Subject: drm: panel: add support for Samsung AMS561RA01 panel with S6E8AA5X01
 controller

Samsung AMS561RA01 is an AMOLED panel, using the Samsung S6E8AA5X01 MIPI
DSI controller. Implement a basic panel driver for such panels.

The driver also initializes a backlight device, which works by changing
the panel's gamma values and aid brightness levels appropriately, with
the help of look-up tables acquired from downstream kernel sources.

Fix bug in nt35560_set_brightness() which causes the function to
erroneously report an error. mipi_dsi_dcs_write() returns either a
negative value when an error occurred or a positive number of bytes
written when no error occurred. The buggy code reports an error under
either condition.

Waveshare touchscreen consists of a DPI panel and a driver board.
The waveshare driver board consists of ICN6211 and a MCU to
convert DSI to DPI and control the backlight.
This driver treats the MCU and ICN6211 board as a whole unit.
It can support all resolution waveshare DSI2DPI based panel,
the timing table should come from 'panel-dpi' panel in the device tree.

Subject: drm/omap: Pass along the format info from .fb_create() to
 drm_helper_mode_fill_fb_struct()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Plumb the format info from .fb_create() all the way to
drm_helper_mode_fill_fb_struct() to avoid the redundant
lookup.

For the fbdev case a manual drm_get_format_info() lookup
is needed.

The patch is based on the driver parts of the patchset at Link:
below, which missed converting the omap driver.

Due to the absence of this change in the patchset at Link:, after the
Fixed: commit below, omap_framebuffer_init() ->
drm_helper_mode_fill_fb_struct() set drm_framebuffer::format incorrectly
to NULL, which lead to the !fb->format WARN() in drm_framebuffer_init()
and causing framebuffer creation to fail. This patch fixes both of these
issues.

v2: Amend the commit log mentioning the functional issues the patch
    fixes. (Tomi)

Subject: drm/nouveau: replace snprintf() with scnprintf() in nvkm_snprintbf()

snprintf() returns the number of characters that *would* have been
written, which can overestimate how much you actually wrote to the
buffer in case of truncation. That leads to 'data += this' advancing
the pointer past the end of the buffer and size going negative.

Switching to scnprintf() prevents potential buffer overflows and ensures
consistent behavior when building the output string.

Subject: drm/nouveau: Remove surplus struct member

struct nouveau_channel contains the member 'accel_done' and a forgotten
TODO which hints at that mechanism being removed in the "near future".
Since that variable is read nowhere anymore, this "near future" is now.

Remove the variable and the TODO.

Subject: drm/gud: Remove unnecessary logging

The debug logging in gud_disconnect() adds zero detail and is
unnecessary, as it only prints the function name.

The same functionality can be achieved by using ftrace, and is
highlighted by checkpatch, stating the same.

This patch removes the debug log in the gud_disconnect() function.

Subject: drm/repaper: Do not access GEM-DMA vaddr directly

Use DRM's shadow-plane helper to map and access the GEM object's buffer
within kernel address space. Encapsulates the vmap logic in the GEM-DMA
helpers.

The repaper driver currently reads the vaddr field from the GME buffer
object directly. This only works because GEM code 'automagically' sets
vaddr.

Shadow-plane helpers perform the same steps, but with correct abstraction
behind drm_gem_vmap(). The shadow-plane state provides the buffer address
in kernel address space and the format-conversion state.

Subject: drm/nouveau: always set RMDevidCheckIgnore for GSP-RM

Always set the RMDevidCheckIgnore registry key for GSP-RM so that it
will continue support newer variants of already supported GPUs.

GSP-RM maintains an internal list of PCI IDs of GPUs that it supports,
and checks if the current GPU is on this list.  While the actual GPU
architecture (as specified in the BOOT_0/BOOT_42 registers) determines
how to enable the GPU, the PCI ID is used for the product name, e.g.
"NVIDIA GeForce RTX 5090".

Unfortunately, if there is no match, GSP-RM will refuse to initialize,
even if the device is fully supported.  Nouveau will get an error
return code, but by then it's too late.  This behavior may be corrected
in a future version of GSP-RM, but that does not help Nouveau today.

Fortunately, GSP-RM supports an undocumented registry key that tells it
to ignore the mismatch.  In such cases, the product name returned will
be a blank string, but otherwise GSP-RM will continue.

Unlike Nvidia's proprietary driver, Nouveau cannot update to newer
firmware versions to keep up with every new hardware release.  Instead,
we can permanently set this registry key, and GSP-RM will continue
to function the same with known hardware.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As per the wa_18038517565, we need to disable FBC compressor
clock gating before enabling FBC and enable after disabling
FBC. Placing the enabling of clock gating in the fbc deactivate
function can make the above wa logic go wrong in case of
frontbuffer rendering FBC mechanism. FBC deactivate can get
called during fb invalidate and then the corresponding FBC
activate can get called without properly disabling the clock
gating and can result in compression stalled. So move the
enable clock gating at the end of one FBC session after FBC
is completely disabled for a pipe.

Subject: drm/i915/psr: Do not trigger Frame Change events from frontbuffer
 flush
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We want to get rid of triggering "Frame Change" events from
frontbuffer flush calls. We are about to move using TRANS_PUSH
register for this on LunarLake and onwards. Touching TRANS_PUSH
register from fronbuffer flush would be problematic as it's written by
DSB as well.

Fix this by using intel_psr_exit when flush or invalidate is done on
LunarLake and onwards. This is not possible on AlderLake and
MeteorLake due to HW bug in PSR2 disable.

This patch is also fixing problems with cursor plane where cursor is
disappearing or duplicate cursor is seen on the screen.

Subject: drm/xe/migrate: prevent infinite recursion

If the buf + offset is not aligned to XE_CAHELINE_BYTES we fallback to
using a bounce buffer. However the bounce buffer here is allocated on
the stack, and the only alignment requirement here is that it's
naturally aligned to u8, and not XE_CACHELINE_BYTES. If the bounce
buffer is also misaligned we then recurse back into the function again,
however the new bounce buffer might also not be aligned, and might never
be until we eventually blow through the stack, as we keep recursing.

Instead of using the stack use kmalloc, which should respect the
power-of-two alignment request here. Fixes a kernel panic when
triggering this path through eudebug.

v2 (Stuart):
 - Add build bug check for power-of-two restriction
 - s/EINVAL/ENOMEM/

Subject: drm/xe/migrate: don't overflow max copy size

With non-page aligned copy, we need to use 4 byte aligned pitch, however
the size itself might still be close to our maximum of ~8M, and so the
dimensions of the copy can easily exceed the S16_MAX limit of the copy
command leading to the following assert:

xe 0000:03:00.0: [drm] Assertion `size / pitch <= ((s16)(((u16)~0U) >> 1))` failed!

WARNING: CPU: 23 PID: 10605 at drivers/gpu/drm/xe/xe_migrate.c:673 emit_copy+0x4b5/0x4e0 [xe]

To fix this account for the pitch when calculating the number of current
bytes to copy.

Subject: drm/xe/migrate: prevent potential UAF

If we hit the error path, the previous fence (if there is one) has
already been put() prior to this, so doing a fence_wait could lead to
UAF. Tweak the flow to do to the put() until after we do the wait.

Subject: drm/xe: Defer buffer object shrinker write-backs and GPU waits
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When the xe buffer-object shrinker allows GPU waits and write-back,
(typically from kswapd), perform multiple passes, skipping
subsequent passes if the shrinker number of scanned objects target
is reached.

1) Without GPU waits and write-back
2) Without write-back
3) With both GPU-waits and write-back

This is to avoid stalls and costly write- and readbacks unless they
are really necessary.

v2:
- Don't test for scan completion twice. (Stuart Summers)
- Update tags.

Subject: drm/xe/hwmon: Add SW clamp for power limits writes

Clamp writes to power limits powerX_crit/currX_crit, powerX_cap,
powerX_max, to the maximum supported by the pcode mailbox
when sysfs-provided values exceed this limit.
Although the pcode already performs clamping, values beyond the pcode
mailbox's supported range get truncated, leading to incorrect
critical power settings.
This patch ensures proper clamping to prevent such truncation.

v2:
 - Address below review comments. (Riana)
 - Split comments into multiple sentences.
 - Use local variables for readability.
 - Add a debug log.
 - Use u64 instead of unsigned long.

v3:
 - Change drm_dbg logs to drm_info. (Badal)

v4:
 - Rephrase the drm_info log. (Rodrigo, Riana)
 - Rename variable max_mbx_power_limit to max_supp_power_limit, as
   limit is same for platforms with and without mailbox power limit
   support.

Subject: drm/amdgpu: Add PSP fw version check for fw reserve GFX command

The fw reserved GFX command is only supported starting from PSP fw
version 0x3a0e14 and 0x3b0e0d. Older versions do not support this command.

Add a version guard to ensure the command is only used when the running
PSP fw meets the minimum version requirement.

This ensures backward compatibility and safe operation across fw
revisions.

Subject: drm/nouveau: Remove DRM_NOUVEAU_GSP_DEFAULT config

This option was originally intoduced because the GSP code path was
not well tested and we wanted to leave it up to distros which code path
they shipped by default. By now though, the GSP path is probably better
tested than the old firmware eg. Fedora ships GSP by default and we
generally run CTS on GSP. We've always been GSP-only on Ada and later.

So, this path removes the option and effectively sets the option to
always on. We still fall back to the old firmware if GSP is not found.
This change only affects Turing and Ampere.

Users can still set nouveau.config=NvGspRm=0 on the kernel command line
to force using the old firmware on Turing/Ampere.

Subject: drm/nouveau: Improve message for missing firmware

This is inteded to address concerns that users might get cryptic error
messages or a failure to boot if they set nouveau.config=NvGspRm=0 on
the kernel command line and their gpu requires gsp (Ada or newer).
With this patch, that configuration results in error messages like this:

nouveau 0000:01:00.0: gsp: Failed to load required firmware for device.
nouveau 0000:01:00.0: gsp ctor failed: -22
nouveau 0000:01:00.0: probe with driver nouveau failed with error -22

When nouveau fails to load like this, we still fall back to the generic
framebuffer device, so users will still have limited graphical output.

Subject: drm/bridge: cdns-dsi: Fix the _atomic_check()

Use the "adjusted_mode" for the dsi configuration check, as that is the
more appropriate display_mode for validation, and later bridge enable.

Also, fix the mode_valid_check parameter from false to true, as the dsi
configuration check is taking place during the check-phase, and the
crtc_* mode values are not expected to be populated yet.

Subject: drm/bridge: cdns-dsi: Drop crtc_* code

With recent change the cdns_dsi_check_conf() is always called with
mode_valid_check = true. We can thus remove all the code related to the
"false" paths.

Subject: drm/bridge: cdns-dsi: Remove broken fifo emptying check

The driver checks if "DPI(HFP) > DSI(HSS+HSA+HSE+HBP)", and rejects the
mode if not.

However, testing shows that this doesn't hold at all. I can set the hfp
to very small values, with no errors. The feedback from the HW team also
was that the check is not right, although it's not clear if there's a
way to validate the FIFO emptying.

The check rejects quite a lot of modes, apparently for no good reason,
so drop the check.

Subject: drm/bridge: cdns-dsi: Drop checks that shouldn't be in .mode_valid()

The docs say about mode_valid():

"it is not allowed to look at anything else but the passed-in mode, and
validate it against configuration-invariant hardware constraints"

We're doing a lot more than just looking at the mode. The main issue
here is that we're doing checks based on the pixel clock, before we know
what the pixel clock from the crtc actually is.

So, drop the cdns_dsi_check_conf() call from .mode_valid().

Subject: drm/bridge: cdns-dsi: Update htotal in cdns_dsi_mode2cfg()

cdns_dsi_mode2cfg() calculates the dsi timings, but for some reason
doesn't set the htotal based on those timings. It is set only later, in
cdns_dsi_adjust_phy_config().

As cdns_dsi_mode2cfg() is the logical place to calculate it, let's move
it there. Especially as the following patch will remove
cdns_dsi_adjust_phy_config().

Subject: drm/bridge: cdns-dsi: Drop cdns_dsi_adjust_phy_config()

cdns_dsi_adjust_phy_config() is called from cdns_dsi_check_conf(), which
is called from .atomic_check(). It checks the DSI htotal and adjusts it
to align on the DSI lane boundary by changing hfp and then recalculating
htotal and HS clock rate.

This has a few problems.

First is the fact that the whole thing is not needed: we do not need to
align on the lane boundary. The whole frame is sent in HS mode, and it
is fine if the line's last byte clock tick fills, say, only 2 of the 4
lanes. The next line will just continue from there. Assuming the
DSI timing values have been calculated to match the incoming DPI stream,
and the HS clock is compatible with the DPI pixel clock, the "uneven"
DSI lines will even out when multiple lines are being sent.

But we could do the align, aligning is not a problem as such. However,
adding more bytes to the hfp, as the function currently does, makes the
DSI line time longer, so the function then adjusts the HS clock rate.
This is where things fail: we don't know what rates we can get from the
HS clock, and at least in TI K3 SoC case the rates are quite coarsely
grained. Thus small adjustment to hfp will lead to a big change in HS
clock rate, and things break down.

We could do a loop here, adjusting hfp, adjusting clock, checking clock
rate, adjusting hfp again, etc., but considering that the whole
adjustment shouldn't be needed at all, it's easier to just remove the
function.

Something like this function should be added back later, when adding
burst mode support, but that's a bigger change and I don't think this
function would help that work in any way.

The Cadence DSI requires negative syncs from the incoming video signal,
but at the moment that requirement is not expressed in any way. If the
crtc decides to use positive syncs, things break down.

Use the adjusted_mode in atomic_check to set the sync flags to negative
ones.

Subject: drm/bridge: cdns-dsi: Fix REG_WAKEUP_TIME value

The driver tries to calculate the value for REG_WAKEUP_TIME. However,
the calculation itself is not correct, and to add on it, the resulting
value is almost always larger than the field's size, so the actual
result is more or less random.

According to the docs, figuring out the value for REG_WAKEUP_TIME
requires HW characterization and there's no way to have a generic
algorithm to come up with the value. That doesn't help at all...

However, we know that the value must be smaller than the line time, and,
at least in my understanding, the proper value for it is quite small.
Testing shows that setting it to 1/10 of the line time seems to work
well. All video modes from my HDMI monitor work with this algorithm.

Hopefully we'll get more information on how to calculate the value, and
we can then update this.

Subject: drm/bridge: cdns-dsi: Use video mode and clean up cdns_dsi_mode2cfg()

The driver does all the calculations and programming with video timings
(hftp, hbp, etc.) instead of the modeline values (hsync_start, ...).
Thus it makes sense to use struct videomode instead of struct
drm_display_mode internally.

Switch to videomode and do some cleanups in cdns_dsi_mode2cfg() along
the way.

Subject: drm/bridge: cdns-dsi: Tune adjusted_mode->clock according to dsi
 needs

The driver currently expects the pixel clock and the HS clock to be
compatible, but the DPHY PLL doesn't give very finely grained rates.
This often leads to the situation where the pipeline just fails, as the
resulting HS clock is just too off.

We could change the driver to do a better job on adjusting the DSI
blanking values, hopefully getting a working pipeline even if the pclk
and HS clocks are not exactly compatible. But that is a bigger work.

What we can do easily is to see in .atomic_check() what HS clock rate we
can get, based on the pixel clock rate, and then convert the HS clock
rate back to pixel clock rate and ask that rate from the crtc. If the
crtc has a good PLL (which is the case for TI K3 SoCs), this will fix
any issues wrt. the clock rates.

If the crtc cannot provide the requested clock, well, we're no worse off
with this patch than what we have at the moment.

Subject: drm/bridge: cdns-dsi: Don't fail on MIPI_DSI_MODE_VIDEO_BURST

While the cdns-dsi does not support DSI burst mode, the burst mode is
essentially DSI event mode with more versatile clocking and timings.
Thus cdns-dsi doesn't need to fail if the DSI peripheral driver requests
MIPI_DSI_MODE_VIDEO_BURST.

In my particular use case, this allows the use of ti-sn65dsi83 driver.

Subject: drm/tidss: remove redundant assignment to variable ret

The assignment of zero to variable is redundant as the following
continue statement loops back to the start of the loop where
ret is assigned a new value from the return to the call to
get_parent_dss_vp. Remove assignment.

Convert the Renesas RZ/G2L MIPI DSI Encoder driver from
SET_RUNTIME_PM_OPS() to RUNTIME_PM_OPS() and pm_ptr().  This lets us
drop the __maybe_unused annotations from its runtime suspend and resume
callbacks, and reduces kernel size in case CONFIG_PM is disabled.

Subject: drm/xe/pf: Set VF LMEM BAR size
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

LMEM is partitioned between multiple VFs and we expect that the more
VFs we have, the less LMEM is assigned to each VF.
This means that we can achieve full LMEM BAR access without the need to
attempt full VF LMEM BAR resize via pci_resize_resource().

Always try to set the largest possible BAR size that allows to fit the
number of enabled VFs and inform the user in case the resize attempt is
not successful.

Update driver to use the "multi" variants of MIPI functions which
facilitate improved error handling and cleaner driver code.

Remove information from a comment which was made obsolete by commit
994ea402c767 ("drm/panel: Rename Sony ACX424 to Novatek NT35560"), which
determined that this driver supports the Novatek NT35560 panel
controller.

Subject: drm/panthor: Add panthor_hw and move gpu_info initialization into it

This patch introduces panthor_hw and moves the initialization of the
gpu_info struct into panthor_hw.c in preparation of handling future GPU
register and naming changes.

Future GPU support can be added by extending panthor_gpu_info_init()
with the necessary register reads behind GPU architecture version guards
if the change is minor. For more complex changes, the function can be
forked and the appropriate function will need to be called based on the
GPU architecture version.

Subject: drm/panthor: Simplify getting the GPU model name

This patch replaces the panthor_model structure with a simple switch
case based on the product_id which is in the format of:
        ((arch_major << 24) | product_major)

This simplifies comparison and allows extending of the function to
accommodate naming differences based on supported GPU features.

Subject: drm/panthor: Add support for Mali-Gx15 family of GPUs

Mali-Gx15 introduces a new GPU_FEATURES register that provides
information about GPU-wide supported features. The register value will
be passed on to userspace via gpu_info.

Additionally, Mali-Gx15 presents an 'Immortalis' naming variant
depending on the shader core count and presence of Ray Intersection
feature support.

This patch adds:
- support for correctly identifying the model names for Mali-Gx15 GPUs.
- arch 11.8 FW binary support

In certain scenarios, it is possible for multiple cache flushes to be
requested before the previous one completes. This patch introduces the
cache_flush_lock mutex to serialize these operations and ensure that
any requested cache flushes are completed instead of dropped.

Subject: drm/panthor: Make MMU cache maintenance use FLUSH_CACHES command

As the FLUSH_MEM and FLUSH_PT MMU_AS commands are deprecated in GPUs
from Mali-Gx20 onwards, this patch adds support for performing cache
maintenance via the FLUSH_CACHES command in GPU_COMMAND in place of
FLUSH_MEM and FLUSH_PT commands.

Mali-Gx10 and Mali-Gx15 GPUs also has support for the FLUSH_CACHES
command and will also use this by default going forward.

Subject: drm/panfrost: Remove redundant pm_runtime_mark_last_busy() calls

pm_runtime_put_autosuspend(), pm_runtime_put_sync_autosuspend(),
pm_runtime_autosuspend() and pm_request_autosuspend() now include a call
to pm_runtime_mark_last_busy(). Remove the now-reduntant explicit call to
pm_runtime_mark_last_busy().

Subject: drm/bridge: display-connector: don't set OP_DETECT for DisplayPorts

Detecting the monitor for DisplayPort targets is more complicated than
just reading the HPD pin level: it requires reading the DPCD in order to
check what kind of device is attached to the port and whether there is
an actual display attached.

In order to let DRM framework handle such configurations, disable
DRM_BRIDGE_OP_DETECT for dp-connector devices, letting the actual DP
driver perform detection. This still keeps DRM_BRIDGE_OP_HPD enabled, so
it is valid for the bridge to report HPD events.

Currently inside the kernel there are only two targets which list
hpd-gpios for dp-connector devices: arm64/qcom/qcs6490-rb3gen2 and
arm64/qcom/sa8295p-adp. Both should be fine with this change.

Subject: drm/gpuvm: Pass map arguments through a struct

We are about to pass more arguments to drm_gpuvm_sm_map[_ops_create](),
so, before we do that, let's pass arguments through a struct instead
of changing each call site every time a new optional argument is added.

Subject: drm/gpuvm: Kill drm_gpuva_init()

drm_gpuva_init() only has one internal user, and given we are about to
add new optional fields, it only add maintenance burden for no real
benefit, so let's kill the thing now.

Subject: drm/gpuvm: Introduce drm_gpuvm_madvise_ops_create

This ops is used to iterate over GPUVA's in the user-provided range
and split the existing sparse VMA's if the start or end of the input
range lies within it. The operations can create up to 2 REMAPS and 2 MAPs.

The primary use case is for drivers to assign attributes to GPU VAs in
the specified range without performing unmaps or merging mappings,
supporting fine-grained control over sparse va's.

+ *               remap   map      remap
+ *
+ * one REMAP and one MAP : Same behaviour as SPLIT and MERGE
+ *
+ * 2) The requested range spans multiple drm_gpuva regions. The logic traverses
+ * across boundaries, remapping the start and end segments, and inserting two
+ * map operations to cover the full range.

+ * are generated to update the affected portion.

+ *
+ * 5) No existing drm_gpuvas. No operations.

Subject: drm/gpusvm: Make drm_gpusvm_for_each_* macros public

The drm_gpusvm_for_each_notifier, drm_gpusvm_for_each_notifier_safe and
drm_gpusvm_for_each_range_safe macros are useful for locating notifiers
and ranges within a user-specified range. By making these macros public,
we enable broader access and utility for developers who need to leverage
them in their implementations.

Subject: drm/panel: panel-samsung-s6e88a0-ams427ap24: Fix includes

Include <linux/property.h> to declare device_property_read_bool() and
<linux/mod_devicetable.h> to declare struct of_device_id. Avoids the
dependency on the backlight header to include both.

Subject: drm_bridge: register content protect property

Some bridges can update HDCP status based on userspace requests if they
support HDCP.

The HDCP property is created after connector initialization and before
registration, just like other connector properties.

Add the content protection property to the connector if a bridge
supports HDCP.
