2018-10-04drm/i915/guc: init GuC descriptors after GuC loadDaniele Ceraolo Spurio
GuC stores some data in there, which might be stale after a reset. We already reset the WQ head and tail, but more things are being moved to the descriptor with the interface updates. Instead of trying to track them one by one, always memset and init the descriptors from scratch after GuC is loaded. The code is also reorganized so that the above operations and the doorbell creation are grouped as "client enabling" v2: add proc_desc_fini for symmetry (Daniele), remove unneeded var init, add guc_is_alive() (Michal) Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Reviewed-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20181002215430.15049-1-daniele.ceraolospurio@intel.com
2018-05-02drm/i915/firmware: Correct URL for firmwareAnusha Srivatsa
Replace 01.org URL with upstream linux-firmware repo URL. We no longer release firmware to 01.org. linux-firmware.git is the ultimate place to find the i915 firmwares.

2018-03-14drm/i915: Implement dynamic GuC WOPCM offset and size calculationJackie Li
Hardware may have specific restrictions on GuC WOPCM offset and size. On Gen9, the value of the GuC WOPCM size register needs to be larger than the value of GuC WOPCM offset register + a Gen9 specific offset (144KB) for reserved GuC WOPCM. Fail to enforce such a restriction on GuC WOPCM size will lead to GuC firmware execution failures. On the other hand, with current static GuC WOPCM offset and size values (512KB for both offset and size), the GuC WOPCM size verification will fail on Gen9 even if it can be fixed by lowering the GuC WOPCM offset by calculating its value based on HuC firmware size (which is likely less than 200KB on Gen9), so that we can have a GuC WOPCM size value which is large enough to pass the GuC WOPCM size check. This patch updates the reserved GuC WOPCM size for RC6 context on Gen9 to 24KB to strictly align with the Gen9 GuC WOPCM layout. It also adds support to verify the GuC WOPCM size aganist the Gen9 hardware restrictions. To meet all above requirements, let's provide dynamic partitioning of the WOPCM that will be based on platform specific HuC/GuC firmware sizes. v2: - Removed intel_wopcm_init (Ville/Sagar/Joonas) - Renamed and Moved the intel_wopcm_partition into intel_guc (Sagar) - Removed unnecessary function calls (Joonas) - Init GuC WOPCM partition as soon as firmware fetching is completed v3: - Fixed indentation issues (Chris) - Removed layering violation code (Chris/Michal) - Created separat files for GuC wopcm code (Michal) - Used inline function to avoid code duplication (Michal) v4: - Preset the GuC WOPCM top during early GuC init (Chris) - Fail intel_uc_init_hw() as soon as GuC WOPCM partitioning failed v5: - Moved GuC DMA WOPCM register updating code into intel_wopcm.c - Took care of the locking status before writing to GuC DMA Write-Once registers.
