Because CRAT_CU_FLAGS_IOMMU_PRESENT was not set in some BIOS crat, we need to workaround this. For future compatibility, we also overwrite the bit in capability according to the value of needs_iommu_device.

CWSR fails on Raven if the control stack is MTYPE_UC, which is used for regular GART mappings. As a workaround we map it using MTYPE_NC. The MEC firmware expects the control stack at one page offset from the start of the MQD so it is part of the MQD allocation on GFXv9. AMDGPU added a memory allocation flag just for this purpose.

For STDU individual screen target size is limited by SVGA_REG_SCREENTARGET_MAX_WIDTH/HEIGHT registers so add that limit during atomic check_modeset. An additional limit is placed in the update_layout ioctl to avoid requesting layouts that current user-space typically can't support.

During atomic check to prepare the new topology no need to check if old_crtc_state was enabled or not. This will cause atomic_check to fail because due to connector routing a crtc can be in atomic_state even if there was no change to enable status. Detected this issue with igt run.

Host prints lots of untracked MMIO at 0x4653c when creating linux guest. "gvt: vgpu 2: untracked MMIO 0004653c len 4" GEN9_CLKGATE_DIS_4 (0x4653c) is accessed by i915 for gmbus clockgating. However vgpu doesn't support any clockgating powergating operations on related mmio access trap so need add it to default handler. GEN9_CLKGATE_DIS_4 is accessed in bxt_gmbus_clock_gating() which only applies to GEN9_LP so doens't show the warning on other platforms. The solution is to add it to default handler init_bxt_mmio_info().

Recent patch fixed the call trace "ERROR Port B enabled but PHY powered down? (PHY_CTL 00000000)". but introduced another similar call trace shown as: "ERROR Port C enabled but PHY powered down? (PHY_CTL 00000200)". The call trace will appear when host and guest enabled different ports, i.e. host using PORT C or neither PORT is enabled, while guest is always using PORT B as simulated by gvt. The issue is actually covered previously before the commit and reverals now when the commit do the right thing. On BXT, some PHY registers are initialized by vbios, before i915 loaded. Later i915 will re-program some, or skip some based on the implementation. The initialized mmio for guest i915 is done by gvt, based on the snapshot taken from host. If host and guest have different PORT enabled, some DPIO PHY mmios that gvt initialized for guest i915 will not match the simualted monitor for guest, which leads to guest i915 print the calltrace when it's trying to enable PHY and PORT. The solution is to init these DPIO PHY registers to default value, then guest i915 will program them to reasonable value based on the default powerwell table and enabled PORT. Together with the old patch, all similar call trace in guest kernel on BXT can be resolved. v2: Move PHY register init to intel_vgpu_reset_mmio (Min) v3: Do not delete empty line in issue fix patch.

As pointed out by Daniel Vetter, we should be usinng drm_drv_uses_atomic_modeset() for determining whether or not we want to make the debugfs nodes for atomic instead of checking DRIVER_ATOMIC, as the former isn't an accurate representation of whether or not the driver is actually using atomic modesetting internally (even though it might not be exposing atomic capabilities).

Trond Myklebust authored
The previous fix broke recovery of delegated stateids because it assumes that if we did not mark the delegation as suspect, then the delegation has effectively been revoked, and so it removes that delegation irrespectively of whether or not it is valid and still in use. While this is "mostly harmless" for ordinary I/O, we've seen pNFS fail with LAYOUTGET spinning in an infinite loop while complaining that we're using an invalid stateid (in this case the all-zero stateid). What we rather want to do here is ensure that the delegation is always correctly marked as needing testing when that is the case. So we want to close the loophole offered by nfs4_schedule_stateid_recovery(), which marks the state as needing to be reclaimed, but not the delegation that may be backing it.
