vi_mqd is only used by VI family but mqd_ptr and mqd_backup is common for all ASIC, so change the pointer to void. Signed-off-by:

v2: use in_rest to fix compute ring test failure issue which occured after FLR/gpu_reset. we need backup a clean status of MQD which was created in drv load stage, and use it in resume stage, otherwise KCQ and KIQ all may faild in ring/ib test. Signed-off-by:

Use no kiq version reg access due to: 1) better performance 2) INTR context consideration (some routine in mailbox is in INTR context e.g.xgpu_vi_mailbox_rcv_irq) Signed-off-by:

some registers are PF & VF copy, and we can safely use mmio method to access them. and sometime we are forbid to use kiq to access registers for example in INTR context. we need a MACRO that always disable KIQ for regs accessing Signed-off-by:

By using ttm_bo_init_reserved instead of the manual initialization of the reservation object, the reservation lock will be properly unlocked and destroyed when the TTM BO initialization fails. Actual deadlocks caused by the missing unlock should have been fixed by "drm/ttm: never add BO that failed to validate to the LRU list", superseding the flawed fix in commit 38fc4856 ("drm/amdgpu: fix a potential deadlock in amdgpu_bo_create_restricted()"). This change fixes remaining recursive locking errors that can be seen with lock debugging enabled, and avoids the error of freeing a locked mutex. As an additional minor bonus, buffers created with resv == NULL and the AMDGPU_GEM_CREATE_VRAM_CLEARED flag are now only added to the global LRU list after the fill commands have been issued. v2: use amdgpu_bo_unreserve instead of ttm_bo_unreserve Fixes: 12a852219583 ("drm/amdgpu: improve AMDGPU_GEM_CREATE_VRAM_CLEARED handling (v2)") Signed-off-by:

This variant of ttm_bo_init returns the validated buffer object with the reservation lock held when resv == NULL. This is convenient for callers that want to use the BO immediately, e.g. for initializing its contents. Signed-off-by:

As the comment says: callers of ttm_bo_init cannot rely on having the only reference to the BO when the function returns successfully. Signed-off-by:

This reverts commit 38fc4856, which introduces a use-after-free. The underlying bug should be properly fixed with "drm/ttm: never add BO that failed to validate to the LRU list". Cc: zhoucm1 <david1.zhou@amd.com> Signed-off-by:

Fixes a potential race condition in amdgpu that looks as follows: Task 1: attempt ttm_bo_init, but ttm_bo_validate fails Task 1: add BO to global list anyway Task 2: grabs hold of the BO, waits on its reservation lock Task 1: releases its reference of the BO; never gives up the reservation lock The patch "drm/amdgpu: fix a potential deadlock in amdgpu_bo_create_restricted()" attempts to fix that by releasing the reservation lock in amdgpu code; unfortunately, it introduces a use-after-free when this race _doesn't_ happen. This patch should fix the race properly by never adding the BO to the global list in the first place. Cc: zhoucm1 <david1.zhou@amd.com> Signed-off-by: -

read_sensor() has been recently implemented for dpm based boards which means amdgpu_sensors can now be exposed. v2: - make sure read_sensor is not NULL on dpm chips - keep sanity check for powerplay chips v3: - make sure amdgpu_dpm != 0 Cc: Tom St Denis <tom.stdenis@amd.com> Reviewed-by:Tom St Denis <tom.stdenis@amd.com> Signed-off-by:

Add the GPU temperature, the shader clock and eventually the memory clock (as well as the GPU load on CI). The main goal is to expose this info to the userspace like Radeon. v2: - add AMDGPU_PP_SENSOR_GPU_LOAD on CI - update the commit description Signed-off-by: -

This update allows sensors to return more than 1 value and indicates to the caller how many bytes are written. The debugfs interface has been updated to handle reading all of the values. Simply seek to the enum value (multiplied by 4) and then read as many bytes as the sensor provides. (v2): Don't set size to 4 before reading GPU_POWER (v3): agd: rebase Signed-off-by:

Till GFX8 we can only enable PRT support globally, but with the next hardware generation we can do this on a per page basis. Keep the interface consistent by adding PRT mappings and enable support globally on current hardware when the first mapping is made. v2: disable PRT support delayed and on all error paths v3: PRT and other permissions are mutal exclusive, PRT mappings don't need a BO. v4: update PRT mappings durign CS as well, make va_flags 64bit Signed-off-by: -
