We set the FW status to "TRANSFERRED" after the load completes and to "RUNNING"once we're done with proxy init, so do the same if we're trying to re-load the FW and it is already loaded. Note that there is no difference in driver behavior between the 2 states, but it's useful to be accurate when we dump the status for debug. Signed-off-by:

The GSC HW is only reset by driver FLR or D3cold entry. We don't support the former at runtime, while the latter is only supported on DGFX, for which we don't support GSC. Therefore, if GSC failed to load previously there is no need to try again because the HW is stuck in the error state. An assert has been added so that if we ever add DGFX support we'll know we need to handle the D3 case. v2: use "< 0" instead of "!= 0" in the FW state error check (Julia).

For non-d3cold-capable devices we'd like to be able to wake up the device from reclaim. In particular, for Lunar Lake we'd like to be able to blit CCS metadata to system at shrink time; at least from kswapd where it's reasonable OK to wait for rpm resume and a preceding rpm suspend. Therefore use a separate lockdep map for such devices and prime it reclaim-tainted. v2: - Rename lockmap acquire- and release functions. (Rodrigo Vivi). - Reinstate the old xe_pm_runtime_lockdep_prime() function and rename it to xe_rpm_might_enter_cb(). (Matthew Auld). - Introduce a separate xe_pm_runtime_lockdep_prime function called from module init for known required locking orders. v3: - Actually hook up the prime function at module init. v4: - Rebase. v5: - Don't use reclaim-safe RPM with sriov.

This optimization relied on having to clear CCS on allocations. If there is no need to clear CCS on allocations then this would mostly help in reducing CPU utilization. Revert this patch at this moment because of: 1 Currently Xe can't do clear on free and using a invalid ttm flag, TTM_TT_FLAG_CLEARED_ON_FREE which could poison global ttm pool on multi-device setup. 2 Also for LNL CPU:WB doesn't require clearing CCS as such BO will not be allowed to bind with compression PTE. Subsequent patch will disable clearing CCS for CPU:WB BOs for LNL. This reverts commit 23683061.

Setting 'nomodeset' on the kernel command line disables all graphics drivers with modesetting capabilities, leaving only firmware drivers, such as simpledrm or efifb. Most DRM drivers automatically support 'nomodeset' via DRM's module helper macros. In xe, which uses regular module_init(), manually call drm_firmware_drivers_only() to test for 'nomodeset'. Do not register the driver if set. v2: - use xe's init table (Lucas) - do NULL test for init/exit functions Signed-off-by:

In XE, display runtime suspend / resume routines are called only if d3cold is allowed. This makes the driver unable to detect any HPDs once the device goes into runtime suspend state in platforms like LNL. Update the display runtime suspend / resume routines to include HPD polling regardless of d3cold status. While xe_display_pm_suspend/resume() performs steps during runtime suspend/resume that shouldn't happen, like suspending MST and they are missing other steps like enabling DC9, this patchset is meant to keep the current behavior wrt. these, leaving the corresponding updates for a follow-up v2: have a separate function for display runtime s/r (Rodrigo) v3: better streamlining of system s/r and runtime s/r calls (Imre) v4: rebased Reviewed-by:

Defer the ggtt node removal to a thread if runtime_pm is not active. The ggtt node removal can be called from multiple places, including places where we cannot protect with outer callers and places we are within other locks. So, try to grab the runtime reference if the device is already active, otherwise defer the removal to a separate thread from where we are sure we can wake the device up. v2: - use xe wq instead of system wq (Matt and CI) - Avoid GFP_KERNEL to be future proof since this removal can be called from outside our drivers and we don't want to block if atomic is needed. (Brost) v3: amend forgot chunk declaring xe_device. v4: Use a xe_ggtt_region to encapsulate the node and remova info, wihtout the need for any memory allocation at runtime. v5: Actually fill the delayed_removal.invalidate (Brost) v6: - Ensure that ggtt_region is not freed before work finishes (Auld) - Own wq to ensures that the queued works are flushed before ggtt_fini (Brost) v7: also free ggtt_region on early !bound return (Auld) v8: Address the null deref (CI) v9: Based on the new xe_ggtt_node for the proper care of the lifetime of the object. v10: Redo the lost v5 change.

In some rare cases, the drm_mm node cannot be removed synchronously due to runtime PM conditions. In this situation, the node removal will be delegated to a workqueue that will be able to wake up the device before removing the node. However, in this situation, the lifetime of the xe_ggtt_node cannot be restricted to the lifetime of the parent object. So, this patch introduces the infrastructure so the xe_ggtt_node struct can be allocated in advance and freed when needed. By having the ggtt backpointer, it also ensure that the init function is always called before any attempt to insert or reserve the node in the GGTT. v2: s/xe_ggtt_node_force_fini/xe_ggtt_node_fini and use it internaly (Brost) v3: - Use GF_NOFS for node allocation (CI) - Avoid ggtt argument, now that we have it inside the node (Lucas) - Fix some missed fini cases (CI) v4: - Fix SRIOV critical case where config->ggtt_region was lost (Michal) - Avoid ggtt argument also on removal (missed case on v3) (Michal) - Remove useless checks (Michal) - Return 0 instead of negative errno on a u32 addr.

The xe_ggtt component uses drm_mm to manage the GGTT. The drm_mm_node is just a node inside drm_mm, but in Xe we use that only in the GGTT context. So, this patch encapsulates the drm_mm_node into a xe_ggtt's new struct. This is the first step towards limiting all the drm_mm access through xe_ggtt. The ultimate goal is to have a better control of the node insertion and removal, so the removal can be delegated to a delayed workqueue. v2: Fix includes and typos (Michal and Brost) Reviewed-by:
