Pull driver core updates from Greg KH: "Here is the large set of driver core changes for 6.4-rc1. Once again, a busy development cycle, with lots of changes happening in the driver core in the quest to be able to move "struct bus" and "struct class" into read-only memory, a task now complete with these changes. This will make the future rust interactions with the driver core more "provably correct" as well as providing more obvious lifetime rules for all busses and classes in the kernel. The changes required for this did touch many individual classes and busses as many callbacks were changed to take const * parameters instead. All of these changes have been submitted to the various subsystem maintainers, giving them plenty of time to review, and most of them actually did so. Other than those changes, included in here are a small set of other things: - kobject logging improvements - cacheinfo improvements and updates - obligatory fw_devlink updates and fixes - documentation updates - device property cleanups and const * changes - firwmare loader dependency fixes. All of these have been in linux-next for a while with no reported problems" * tag 'driver-core-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (120 commits) device property: make device_property functions take const device * driver core: update comments in device_rename() driver core: Don't require dynamic_debug for initcall_debug probe timing firmware_loader: rework crypto dependencies firmware_loader: Strip off \n from customized path zram: fix up permission for the hot_add sysfs file cacheinfo: Add use_arch[|_cache]_info field/function arch_topology: Remove early cacheinfo error message if -ENOENT cacheinfo: Check cache properties are present in DT cacheinfo: Check sib_leaf in cache_leaves_are_shared() cacheinfo: Allow early level detection when DT/ACPI info is missing/broken cacheinfo: Add arm64 early level initializer implementation cacheinfo: Add arch specific early level initializer tty: make tty_class a static const structure driver core: class: remove struct class_interface * from callbacks driver core: class: mark the struct class in struct class_interface constant driver core: class: make class_register() take a const * driver core: class: mark class_release() as taking a const * driver core: remove incorrect comment for device_create* MIPS: vpe-cmp: remove module owner pointer from struct class usage. ...

drm/amdkfd: Add gfx_target_version for GC 9.4.3

drm/amdkfd: Enable HW_UPDATE_RPTR on GC 9.4.3

2023-04-14T17:47:48Z

GC 9.4.3 uses the hardware to update AQL queues read pointer, so remove CP_HQD_PQ_CONTROL__NO_UPDATE_RPTR_MASK flag from MQD if it's GC 9.4.3, and keep it for other existing gfx9 ASICs. Signed-off-by: Amber Lin Acked-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Enable IH retry CAM on GFX9

2023-04-13T04:14:08Z

This patch enables the IH retry CAM on GFX9 series cards. This retry filter is used to prevent sending lots of retry interrupts in a short span of time and overflowing the IH ring buffer. This will also help reduce CPU interrupt workload. Signed-off-by: Mukul Joshi Reviewed-by: Felix Kuehling Signed-off-by: Alex Deucher

drm/amdgpu: Enable GFX11 SDMA context empty interrupt

2023-04-11T22:03:45Z

Enable SDMA queue empty context switching. SDMA context switch due to quantum programming no longer done here (as of sdma v6), so re-name sdma_v6_0_ctx_switch_enable to sdma_v6_0_ctxempty_int_enable to reflect this. Also program SDMAx_QUEUEx_SCHEDULE_CNTL for context switch due to quantum in KFD. Set to amdgpu_sdma_phase_quantum (defaults to 32 i.e. 3200us).

drm/amdkfd: Check PCIe atomics support on GFX11 to set CP_HQD_HQ_STATUS0[29]

2023-04-11T22:03:45Z

CP_HQD_HQ_STATUS0[29] bit will be used by CPFW to acknowledge whether PCIe atomics are supported. The default value of this bit is set to 0. Driver will check whether PCIe atomics are supported and set the bit to 1 if supported. This will force CPFW to use real atomic ops. If the bit is not set, CPFW will default to read/modify/write using the firmware itself. This is applicable only to GFX11 RS64 CP with MEC FW >= 509. If MEC FW < 509 and for all GFX11 F32 CP, PCIe atomics needs to be supported else it will skip the device. This commit also involves moving amdgpu_amdkfd_device_probe() function call after per-IP early_init loop in amdgpu_device_ip_early_init() function so as to check for RS64 enabled device.

drm/amdkfd: Set TG_CHUNK_SIZE for GC 9.4.3

2023-03-31T15:18:55Z

On GC 9.4.3, DW 41 in MQD is repurposed as compute_tg_chunk_size for cooperative dispatch. When it's a AQL queue, set compute_tg_chunk_size as 1 to spread work groups evenly among XCCs. If it's PM4 queue, unset compute_tg_chunk_size to disable cooperative mode. v3: set compute_tg_chunk_size as 1 instead of #CUs per XCC v2: set compute_tg_chunk_size as #CUs per XCC instead of total wave slots per XCC Signed-off-by: Amber Lin Reviewed-by: Sean Keely Signed-off-by: Alex Deucher
