Cleanup the kfd code by removing the unused old debugger implementation. The address watch was only ever implemented in the upstream driver for GFXv7 (Kaveri). The user mode tools runtime using this API was never open-sourced. Work on the old debugger prototype that used this API has been discontinued years ago. Only a small piece of resetting wavefronts is kept and is moved to kfd_device_queue_manager.c. Signed-off-by:

[Why] Found when running igt@kms_atomic. Userspace attempts to do a TEST_COMMIT when 0 streams which calls dc_remove_stream_from_ctx. This in turn calls link_enc_unassign which ends up modifying stream->link = NULL directly, causing the global link_enc to be removed preventing further link activity and future link validation from passing. [How] We take care of link_enc unassignment at the start of link_enc_cfg_link_encs_assign so this call is no longer necessary. Fixes global state from being modified while unlocked. Reviewed-by:

As the enabled ppfeatures are just retrieved ahead. We can use that directly instead of retrieving again and again. Signed-off-by:
-
Evan Quan authored
The following scenarios make the driver cache for enabled ppfeatures outdated and invalid: - Other tools interact with PMFW to change the enabled ppfeatures. - PMFW may enable/disable some features behind driver's back. E.g. for sienna_cichild, on gfxoff entering, PMFW will disable gfx related DPM features. All those are performed without driver's notice. Also considering driver does not actually interact with PMFW such frequently, the benefit brought by such cache is very limited. Signed-off-by: -
Evan Quan authored
The supported features should be retrieved just after EnableAllDpmFeatures message complete. And the check(whether some dpm feature is supported) is only needed when we decide to enable or disable it. Signed-off-by:

[Why] pflip interrupt order are mapped 1 to 1 to otg id. e.g. if irq_src=26 corresponds to otg0 then 27->otg1, 28->otg2... Linux DM registers pflip interrupts per number of crtcs. In fused pipe case crtc numbers can be less than otg id. e.g. if one pipe out of 3(otg#0-2) is fused adev->mode_info.num_crtc=2 so DM only registers irq_src 26,27. This is a bug since if pipe#2 remains unfused DM never gets otg2 pflip interrupt (irq_src=28) That may results in gfx failure due to pflip timeout.

Bypass group programming (utcl2_harvest) aims to forbid UTCL2 to send invalidation command to harvested SE/SA. Once invalidation command comes into harvested SE/SA, SE/SA has no response and system hang. This patch is to add checking if the GART table is already allocated before invalidating TLB. The new procedure is as following: 1. Calling amdgpu_gtt_mgr_init() in amdgpu_ttm_init(). After this step GTT BOs can be allocated, but GART mappings are still ignored. 2. Calling amdgpu_gart_table_vram_alloc() from the GMC code. This allocates the GART backing store. 3. Initializing the hardware, and programming the backing store into VMID0 for all VMHUBs. 4. Calling amdgpu_gtt_mgr_recover() to make sure the table is updated with the GTT allocations done before it was allocated. Signed-off-by:
