This patch add gvt resume wrapper into i915_drm_resume(). GVT relies on i915 so resume gvt at last. V2: - Direct call into gvt suspend/resume wrapper in intel_gvt.h/intel_gvt.c. The wrapper and implementation will check and call gvt routine. (zhenyu) V3: Refresh. V4: Rebase. V5: Fail intel_gvt_suspend() if fail to save GGTT. V6: Save host entry to per-vGPU gtt.ggtt_mm on each host_entry update so only need the resume routine. V7: Refresh. Reviewed-by:

This patch save/restore necessary GVT info during i915 suspend/resume so that GVT enabled QEMU VM can continue running. Only GGTT and fence regs are saved/restored now. GVT will save GGTT entries on each host_entry update, restore the saved dirty entries and re-init fence regs in resume routine. V2: - Change kzalloc/kfree to vzalloc/vfree since the space allocated from kmalloc may not enough for all saved GGTT entries. - Keep gvt suspend/resume wrapper in intel_gvt.h/intel_gvt.c and move the actual implementation to gvt.h/gvt.c. (zhenyu) - Check gvt config on and active with intel_gvt_active(). (zhenyu) V3: (zhenyu) - Incorrect copy length. Should be num entries * entry size. - Use memcpy_toio()/memcpy_fromio() instead of memcpy for iomem. - Add F_PM_SAVE flags to indicate which MMIOs to save/restore for PM. V4: Rebase. V5: Fail intel_gvt_save_ggtt as -ENOMEM if fail to alloc memory to save ggtt. Free allocated ggtt_entries on failure. V6: Save host entry to per-vGPU gtt.ggtt_mm on each host_entry update. V7: Restore GGTT entry based on present bit. Split fence restore and mmio restore in different functions. Reviewed-by:

If the VBT assigned tc->legacy_port mismatches the live_status indicator for the connector, we ignore the VBT directive and switch over to the HW setting. This is not a driver error, unless we happen to misparse the VBT or the live_status registers. However, for the system in CI where the error is only reported on 1 port out of 4, the evidence indicates the VBT is wrong. Stop flaging this as an error since the cause is beyond our control, fixup the mistake and continue on. Signed-off-by:

ibx_irq_pre_postinstall() looks totally pointless. We can just init both SDEIMR and SDEIER at the same time before enabling the master interrupt. It's equally racy as the other order due to doing all of this from the postinstall stage with the interrupt handler already in place. That is, safe with MSI but racy with shared legacy interrupts. Fortunately we should have MSI on all ilk+. Signed-off-by:

No reason that I can see why we should enable the hpd detection logic already during irq postinstall phase. We don't even do this on all the platforms. We just need it before we actually enable the hotplug interrupts in .hpd_irq_setup(), and in fact we already do it there as well. Let's just eliminate the redundant early setup. Signed-off-by:

Let's pimp the DDI encoder->name to reflect what the spec calls them. Ie. on pre-tgl DDI A-F, on tgl+ DDI A-C or DDI TC1-6. Also since each encoder is really a combination of the DDI and the PHY we include the PHY name as well. ICL is a bit special since it already has the two different types of DDIs (combo or TC) but it still calls them just DDI A-F regarless of the type. For that let's add an extra "(TC)" note to remind is which type of DDI it really is. The code is darn ugly, but not sure there's much we can do about it. Reviewed-by:

The atomic check hooks must look up the encoder to be used with a connector from the connector's atomic state, and not assume that it's the connector's current attached encoder. The latter one can change under the atomic check func, or can be unset yet as in the case of MST connectors.

Writes to CURSURFLIVE in TGL are causing IOMMU errors and visual glitches that are often reproduced when executing CPU intensive workloads while a eDP 4K panel is attached. Manually exiting PSR causes the frontbuffer to be updated without glitches and the IOMMU errors are also gone but this comes at the cost of less time with PSR active. So using this workaround until this issue is root caused and a better fix is found. The current code is already ready to enable PSR after this exit if there is not other frontbuffer modifications. Adding a new if block in psr_force_hw_tracking_exit() instead of reuse the else/gen8- block because the plan is to revert this workaround as soon as a better solution is found.

There is no GEN6_RPSTAT1 on ILK. Instead of reading that let's try to get the same information from MEMSTAT_ILK. At least it seems to track MEMSWCTL frequency request perfectly on my ILK. It needs the same invert trick as the request value. We don't want to put the invert thing into intel_gpu_freq() and intel_freq_opcode() because that would incorrectly invert the min/max/etc frequencies also. One day someone might want to reverse engineer the formula for converting these numbers to Hz, but for now we'll just report them raw. Signed-off-by:

Restore RPS for ILK-M. We lost it when an extra HAS_RPS() check appeared in intel_rps_enable(). Unfortunaltey this just makes the performance worse on my ILK because intel_ips insists on limiting the GPU freq to the minimum. If we don't do the RPS init then intel_ips will not limit the frequency for whatever reason. Either it can't get at some required information and thus makes wrong decisions, or we mess up some weights/etc. and cause it to make the wrong decisions when RPS init has been done, or the entire thing is just wrong. Would require a bunch of reverse engineering to figure out what's going on.
