Interrupt registers 1900xx are VF accessible but only until version 12.50 as on newer platforms VFs are using memory-based interrupts. To avoid complexity, we mark those registers with XE_REG_OPTION_VF unconditionally, as IRQ handling on newer VFs is different anyway. Signed-off-by:

Although MOCS registers became multicast in graphics version 12.50 on the primary GT, this transition did not happen until version 20 on the media GT. Considering each GT independently is mostly important for MTL/ARL where the Xe_LPM+ IP has non-MCR MOCS registers, even though Xe_LPG IP has MCR registers.

Starting on Xe2, the GSCCS engine reset is a 2-step process. When the driver or the GuC hits the GDRST register, the CS is immediately reset and a success is reported, but the GSC shim continues its reset in the background. While the shim reset is ongoing, the CS is able to accept new context submission, but any commands that require the shim will be stalled until the reset is completed. This means that we can keep submitting to the GSCCS as long as we make sure that the preemption timeout is big enough to cover any delay introduced by the reset; since the GSC preempt timeout is not tunable at runtime, we only need to check that the value set in kconfig is big enough (and increase it if it isn't). When the shim reset completes, a specific CS interrupt is triggered, in response to which we need to check the GSCI_TIMER_STATUS register to see if the reset was successful or not. Note that the GSCI_TIMER_STATUS register is not power save/restored, so it gets reset on MC6 entry. However, a reset failure stops MC6, so in that scenario we're always guaranteed to find the correct value. Since we can't check the register within interrupt context, the existing GSC worker has been updated to handle it. The expected action to take on ER failure is to trigger a driver FLR, but we still don't support that, so for now we just print an error. A comment has been added to the code to keep track of the FLR requirement. v2: Add a check for the initial timeout value (Alan) Signed-off-by:

Doing a XE_EXEC with num_batch_buffer == 0 makes signals passed as argument to be signaled when the last real XE_EXEC is completed. But to do that it was first pinning all VMAs in drm_gpuvm_exec_lock(), this patch remove this pinning as it is not required. This change also help Mesa implementing memory over-commiting recovery as it needs to unbind not needed VMAs when the whole VM can't fit in GPU memory but it can only do the unbiding when the last XE_EXEC is completed. So with this change Mesa can get the signal it want without getting out-of-memory errors.

Matt Roper authored
For modern platforms (MTL and later), both kernel and userspace drivers are expected to apply GT programming and workarounds based on the IP version and stepping self-reported by the GT hardware via the GMD_ID registers. Since userspace drivers can't access these registers directly, pass along the version and stepping information via the GT list query. Note that the new query fields will remain 0's when running on pre-GMD_ID platforms. Userspace is expected to continue using PCI devid / revid on those older platforms. Although the hardware also has a GMD_ID register for display version/stepping, that value is intentionally *not* included anywhere in the Xe uapi. Display userspace should be using platform-agnostic APIs and auto-detecting platform capabilities rather than matching specific IP versions. v2: - s/revid/rev/ (Lucas) - Fix kerneldoc copy/paste mistakes Signed-off-by:

With the current state GUC_WA_RCS_REGS_IN_CCS_REGS_LIST could in theory be removed since there is no render register being added to the list of compute WAs. However the real issue is that 18020744125 is incomplete and not setting the RING_HWSTAM on render as it should. Writing this in RTP is a little more tricky as we want to write to another's engine base when the match happens: first compute engine and no render present. So use RING_HWSTAM(RENDER_RING_BASE) instead of the usual XE_RTP_ACTION_FLAG(ENGINE_BASE). Reviewed-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.

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.
