The maximum timeout display uses in xe_pcode_request is 3 msec, add the warning in cases the function is misused with higher timeouts. Add a warning if pcode_try_request is not passed the timeout parameter greater than 0. Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by:

xe_force_wake_init_gt() is a software-only initialization and doesn't need to be called from xe_device_probe(). Move it to initialize together with the gt. Reviewed-by:

Lucas De Marchi authored
Early shall be early enough, stop doing other things with gt before it. Now that xe_gt_init_early() doesn't need forcewake and doesn't depend on the fake engine_mask initialization, move it where it belongs: it doesn't need to be after hwconfig config anymore. Reviewed-by:

Forcewake used to be needed in xe_gt_init_early() since it was calling xe_gt_topology_init(). That call was dropped in commit 4c47049d ("drm/xe/guc: Fix missing topology init"), but the forcewake calls were left behind. Remove them. Cc: Zhanjun Dong <zhanjun.dong@intel.com> Reviewed-by:

The default behavior of device atomics depends on the VM type and buffer allocation types. Device atomics are expected to function with all types of allocations for traditional applications/APIs. Additionally, in compute/SVM API scenarios with fault mode or LR mode VMs, device atomics must work with single-region allocations. In all other cases device atomics should be disabled by default also on platforms where we know device atomics doesn't on work on particular allocations types. v3: fault mode requires LR mode so only check for LR mode to determine compute API(Jose). Handle SMEM+LMEM BO's migration to LMEM where device atomics is expected to work. (Brian). v2: Fix platform checks to correct atomics behaviour on PVC.
