drm/amdgpu: add apu flags (v2)

2020-05-22T17:41:53Z

Add some APU flags to simplify handling of different APU variants. It's easier to understand the special cases if we use names flags rather than checking device ids and silicon revisions. v2: rebase on latest code Acked-by: Evan Quan Acked-by: Christian König Signed-off-by: Alex Deucher

drm/amd/display: Add DC Debug mask to disable features for bringup

2020-05-21T16:37:19Z

[Why] At bringup we want to be able to disable various power features. [How] These features are already exposed as dc_debug_options and exercised on other OSes. Create a new dc_debug_mask module parameter and expose relevant bits, in particular * DC_DISABLE_PIPE_SPLIT * DC_DISABLE_STUTTER * DC_DISABLE_DSC * DC_DISABLE_CLOCK_GATING Signed-off-by: Harry Wentland Reviewed-by: Nicholas Kazlauskas Signed-off-by: Alex Deucher

drm/amdgpu: Add autodump debugfs node for gpu reset v8

2020-05-18T15:23:37Z

When GPU got timeout, it would notify an interested part of an opportunity to dump info before actual GPU reset. A usermode app would open 'autodump' node under debugfs system and poll() for readable/writable. When a GPU reset is due, amdgpu would notify usermode app through wait_queue_head and give it 10 minutes to dump info. After usermode app has done its work, this 'autodump' node is closed. On node closure, amdgpu gets to know the dump is done through the completion that is triggered in release(). There is no write or read callback because necessary info can be obtained through dmesg and umr. Messages back and forth between usermode app and amdgpu are unnecessary. v2: (1) changed 'registered' to 'app_listening' (2) add a mutex in open() to prevent race condition v3 (chk): grab the reset lock to avoid race in autodump_open, rename debugfs file to amdgpu_autodump, provide autodump_read as well, style and code cleanups v4: add 'bool app_listening' to differentiate situations, so that the node can be reopened; also, there is no need to wait for completion when no app is waiting for a dump. v5: change 'bool app_listening' to 'enum amdgpu_autodump_state' add 'app_state_mutex' for race conditions: (1)Only 1 user can open this file node (2)wait_dump() can only take effect after poll() executed. (3)eliminated the race condition between release() and wait_dump() v6: removed 'enum amdgpu_autodump_state' and 'app_state_mutex' removed state checking in amdgpu_debugfs_wait_dump Improve on top of version 3 so that the node can be reopened. v7: move reinit_completion into open() so that only one user can open it. v8: remove complete_all() from amdgpu_debugfs_wait_dump().

drm/amdgpu: implement TMZ accessor (v3)

2020-04-28T20:20:29Z

Implement an accessor of adev->tmz.enabled. Let not code around access it as "if (adev->tmz.enabled)" as the organization may change. Instead... Recruit "bool amdgpu_is_tmz(adev)" to return exactly this Boolean value. That is, this function is now an accessor of an already initialized and set adev and adev->tmz. Add "void amdgpu_gmc_tmz_set(adev)" to check and set adev->gmc.tmz_enabled at initialization time. After which one uses "bool amdgpu_is_tmz(adev)" to query whether adev supports TMZ. Also, remove circular header file include. v2: Remove amdgpu_tmz.[ch] as requested. v3: Move TMZ into GMC. Signed-off-by: Luben Tuikov Acked-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: add tmz feature parameter (v2)

2020-04-28T20:20:28Z

This patch adds tmz parameter to enable/disable the feature in the amdgpu kernel module. Nomally, by default, it should be auto (rely on the hardware capability). But right now, it need to set "off" to avoid breaking other developers' work because it's not totally completed. Will set "auto" till the feature is stable and completely verified. v2: add "auto" option for future use. Signed-off-by: Huang Rui Reviewed-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu: request reg_val_offs each kiq read reg

2020-04-23T19:06:41Z

According to the current kiq read register method, there will be race condition when using KIQ to read register if multiple clients want to read at same time just like the expample below: 1. client-A start to read REG-0 throguh KIQ 2. client-A poll the seqno-0 3. client-B start to read REG-1 through KIQ 4. client-B poll the seqno-1 5. the kiq complete these two read operation 6. client-A to read the register at the wb buffer and get REG-1 value Therefore, use amdgpu_device_wb_get() to request reg_val_offs for each kiq read register. v2: fix the error remove v3: fix the print typo v4: remove unused variables Signed-off-by: Yintian Tao Reviewed-by: Christian König Signed-off-by: Alex Deucher
