With dynamic load-balancing disabled on the compute side, there's no reason left to enable WA 16015675438. Drop it from both PVC and DG2. Note that this can be done because now the driver always set a fixed partition of EUs during initialization via the ccs_mode configuration.

ARL-H uses the same media and display IP as MTL, and a version 12.74 graphics IP (referred to as Xe_LPG+). From a driver point of view, we should be able to just treat the whole platform as MTL and rely on GRAPHICS_VERx100 checks to handle any spots where ARL's Xe_LPG+ needs different handling from MTL's Xe_LPG (i.e., workarounds). v2: Resolve conflict and Reorder PCI ids in sorted order v3: Append signed-off-by commiter to this commit Bspec: 55420 Signed-off-by:

With mem_access going away and pm_runtime getting called instead, we need to protect these against recursions. The put is asynchronous so there's no need to block it. However, for a proper balance, we need to ensure that the references are taken and restored regardless of the flow. So, let's convert them all to void and use some direct linux/pm_runtime functions. v2: Rebased and update commit message (Matt). Cc: Matthew Auld <matthew.auld@intel.com> Reviewed-by:

Introduce the resume and get to fulfill the display need for checking if the device was actually resumed (or it is awake) and the reference was taken. Then we can convert the remaining cases to a void function and have individual functions for individual cases. Also, already start this new function protected from the runtime recursion, since runtime_pm will need to call for display functions for a proper D3Cold flow.

i915's intel_runtime_pm_get_if_in_use actually calls the pm_runtime_get_if_active() with ign_usage_count = false, but Xe was erroneously calling it with true because of the mem_access cases. This can lead to unnecessary references getting hold here and device never getting into the runtime suspended state. Let's use directly the 'if_in_use' function provided by linux/pm_runtime. Also, already start this new function protected from the runtime recursion, since runtime_pm will need to call for display functions for a proper D3Cold flow. v2: Update commit message based on Matt's feedback.

LNCFCMOCS31[31:16] is read-only for DG2 and MTL, so it's not possible to check set it. While trying to set doesn't cause any issue, later when it's read back to check if the value got correctly recorded causes the test to fail. Now that test is reliable for an odd number of entries, reduce it so the last entry is ignored.

Refactor the mocs/l3cc kunit test to support odd number of entries. This switches out from the "check the register value" approach to check the entry value if it makes sense from the register read. This provides an easier output to reason about and cross check with bspec. Some code reordering and variable re-use was also done so the 2 functions follow more or less the same logic. Reviewed-by:

The warn-once in __init_mocs_table() to make sure there's an index set for unused entries is more a sanity check that should be done as the first thing in that function. The kunit test replicates the same check, so also move it up and turn it into a failure condition for the test. Reviewed-by:

Mesa has been issuing a single bind operation per ioctl since xe.ko changed to GPUVA due xe.ko bug #746. If I change Mesa to try again to issue every single bind operation it can in the same ioctl, it hits the MAX_BINDS assertion when running Vulkan conformance tests. Test dEQP-VK.sparse_resources.transfer_queue.3d.rgba32i.1024_128_8 issues 960 bind operations in a single ioctl, it's the most I could find in the conformance suite. I don't see a reason to keep the MAX_BINDS restriction: it doesn't seem to be preventing any specific issue. If the number is too big for the memory allocations, then those will fail. Nothing related to num_binds seems to be using the stack. Let's just get rid of it.
