There is bug in DG2 where if the CCS contexts switches out while the RCS is running it can cause memory corruption. To workaround this add an atomic to a memory address with a value 1 and semaphore wait to the same address for a value of 0. The GuC firmware is responsible for writing 0 to the memory address when it is safe for the context to switch out.

There are some workarounds for DG2 that are implemented in the GuC firmware. However, the KMD is required to enable these by setting the appropriate flag as GuC does not know what platform it is running on.

Initiating a reset when the command streamer is not idle or in the middle of executing an MI_FORCE_WAKE can result in a hang. Multiple command streamers can be part of a single reset domain, so resetting one would mean resetting all command streamers in that domain. To workaround this, before initiating a reset, ensure that all command streamers within that reset domain are either IDLE or are not executing a MI_FORCE_WAKE. Enable GuC PRE_PARSER WA bit so that GuC follows the WA sequence when initiating engine-resets. For gt-resets, ensure that i915 applies the WA sequence. Opens to address in future patches: - The part of the WA to wait for pending forcewakes is also applicable to execlists backend. - The WA also needs to be applied for gen11 Signed-off-by: Umesh Nerlige Ramappa <umesh.nerlige.ramappa@intel.com> Reviewed-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Signed-off-by: John Harrison <John.C.Harrison@Intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220415224025.3693037-3-umesh.nerlige.ramappa@intel.com

Newer platforms have DSS that aren't necessarily available for both geometry and compute, two queries will need to exist. This introduces the first, when passing a valid engine class and engine instance in the flags returns a topology describing geometry. Based on past discussion, we currently only support this new query item on Xe_HP and beyond; earlier platforms do not need to worry about geometry and compute pipelines having access to different topology and should continue to use the existing topology query. v2: fix white space errors v3: change flags from hosting 2 8 bit numbers to holding a i915_engine_class_instance struct v4: add error if non rcs engine passed. v5 (by MattR): - Improve kerneldoc and cross references to related structs/enums.

The latest GuC firmware drops the context descriptor pool in favour of passing all creation data in the create H2G. It also greatly simplifies the work queue and removes the process descriptor used for multi-LRC submission. So, remove all mention of LRC and process descriptors and update the registration code accordingly. Unfortunately, the new API also removes the ability to set default values for the scheduling policies at context registration time. Instead, a follow up H2G must be sent. The individual scheduling policy update H2G commands are also dropped in favour of a single KLV based H2G. So, change the update wrappers accordingly and call this during context registration.. Of course, this second H2G per registration might fail due to being backed up. The registration code has a complicated state machine to cope with the actual registration call failing. However, if that works then there is no support for unwinding if a further call should fail. Unwinding would require sending a H2G to de-register - but that can't be done because the CTB is already backed up. So instead, add a new flag to say whether the context has a pending policy update. This is set if the policy H2G fails at registration time. The submission code checks for this flag and retries the policy update if set. If that call fails, the submission path early exists with a retry error. This is something that is already supported for other reasons.

When we are swapping out the local memory obj on flat-ccs capable platform, we need to capture the ccs data too along with main meory and we need to restore it when we are swapping in the content. When lmem object is swapped into a smem obj, smem obj will have the extra pages required to hold the ccs data corresponding to the lmem main memory. So main memory of lmem will be copied into the initial pages of the smem and then ccs data corresponding to the main memory will be copied to the subsequent pages of smem. ccs data is 1/256 of lmem size. Swapin happens exactly in reverse order. First main memory of lmem is restored from the smem's initial pages and the ccs data will be restored from the subsequent pages of smem. Extracting and restoring the CCS data is done through a special cmd called XY_CTRL_SURF_COPY_BLT v2: Fixing the ccs handling v3: Handle the ccs data at same loop as main memory [Thomas] v4: changes for emit_copy_ccs v5: handle non-flat-ccs scenario Signed-off-by: Ramalingam C <ramalingam.c@intel.com> Reviewed-by: Thomas Hellstrom <thomas.hellstrom@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220405150840.29351-10-ramalingam.c@intel.com

On Xe-HP and later devices, dedicated compression control state (CCS) stored in local memory is used for each surface, to support the 3D and media compression formats. The memory required for the CCS of the entire local memory is 1/256 of the local memory size. So before the kernel boot, the required memory is reserved for the CCS data and a secure register will be programmed with the CCS base address So when an object is allocated in local memory, dont need to explicitly allocate the space for ccs data. But when the obj is evicted into the smem, to hold the compression related data along with the obj extra space is needed in smem. i.e obj_size + (obj_size/256). Hence when a smem pages are allocated for an obj with lmem placement possibility we create with the extra pages required for the ccs data for the obj size. v2: Used imperative wording [Thomas] v3: Inflate the pages only when obj's placement is lmem only v4: GEM_BUG_ON if the ttm->num_pages > obj page size [Thomas] Signed-off-by: Ramalingam C <ramalingam.c@intel.com> cc: Christian Koenig <christian.koenig@amd.com> cc: Hellstrom Thomas <thomas.hellstrom@intel.com> Reviewed-by: Thomas Hellstrom <thomas.hellstrom@linux.intel.com> Reviewed-by: Nirmoy Das <nirmoy.das@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220405150840.29351-9-ramalingam.c@intel.com
