i915_suspend() is called from the DRM legacy S3 suspend/S4 freeze paths and the switcheroo suspend path. For switcheroo we only ever need to perform a full suspend (PM_EVENT_SUSPEND) and for the DRM legacy path we can handle the S4 freeze (PM_EVENT_FREEZE) the same way as S3 suspend. The only difference atm between suspend and freeze is that during freeze we don't disable the PCI device, but there is no reason why we can't do so. So unify the two cases to reduce complexity. Note that for the DRM legacy case the thaw event is not handled, so we disable the display before creating the hibernation image and it won't get re-enabled until reboot. We could fix this leaving the display enabled for the image creation/writing (if we care enough about UMS), but this can be done as a follow-up. Signed-off-by:

The number of DWords should be even when doing ring emits as command sequences require QWord alignment. There was some discussion about the maximum length of the MI_LRI command. Quoting Mika "I did some test with bdw: "The maximum is 128 writes, resulting the 8 bit length field of the command being 0xff, thus following the spec. The 128'th write went through. "Perhaps the max command length is then less in older gens? "Perhaps WARN_ON(x > 128) in MI_LOAD_REGISTER_IMM would be in place but one needs minor tweak to command parser a bit also then. #define I915_MAX_WA_REGS 16 keeps us safe for now atleast." Ville commented that on pre-gen6 the length field seems to be restricted to 0x3f though. So for all cases we should be ok. v2: user LRI variant that can write multiple regs in one go (Damien). We can simply insert one NOP at the end instead of one per register write. Cc: Mika Kuoppala <mika.kuoppala@intel.com> Signed-off-by:

The cursor plane also supports 180 degree rotation. Add a new "cursor-rotation" property on the crtc which controls this. Unlike sprites, the cursor has a fixed size, so if you have a small cursor image with the rest of the bo filled by transparent pixels, simply flipping the rotation property will cause the visible part of the cursor to shift. This is something to keep in mind when using cursor rotation. v2: Fix gen4/vlv by offsetting the base address appropriately v3: Removing cursor-rotation property and using rotation property on cursor plane. v4: Changing the author name back to Ville. v5 (by Matt Roper): Slight tweaking to apply against latest di-nightly codebase.

Current chv spec teels we can only use either 16 or 32 bits as precision. Although in the past VLV went from 16/32 to 32/64 and spec might not be updated, these precision values brings stability and fixes some issues Wayne was facing.

For some yet-undiscovered reason, when IPS gets enabled, the pipe CRC changes. Since hsw_enable_ips() doesn't really guarantees to enable IPS (it depends on package C-states), we can't really predict if IPS is enabled or disabled while running our CRC tests, so let's just completely disable IPS while pipe CRCs are being used. If we find a way to make IPS not change the pipe CRC result, we may want to fix IPS and then revert this patch. While this doesn't happen, let's merge this patch, so every IGT test relying on the CRCs can work on pipe A.

Some machines (like MBAs) might use a tiled framebuffer but not enable display swizzling at boot time. We want to preserve that configuration if possible to prevent a boot time mode set. On IVB+ it shouldn't affect performance anyway since the memory controller does internal swizzling anyway. For most other configs we'll be able to enable swizzling at boot time, since the initial framebuffer won't be tiled, thus we won't see any corruption when we enable it. v2: preserve swizzling if BIOS had it set (Daniel) v3: preserve swizzling only if we inherited a tiled framebuffer (Daniel) check display swizzle setting in detect_bit_6_swizzle (Daniel) use gen6 as cutoff point (Daniel) v4: fixup swizzle preserve again, had wrong init order (Daniel) Reported-by:Kristian Høgsberg <hoegsberg@gmail.com> Signed-off-by:

During S4 freeze we don't call intel_suspend_complete(), which would save the gunit HW state, but during S4 thaw/restore events we call intel_resume_prepare() which restores it, thus ending up in a corrupted HW state. Fix this by calling intel_suspend_complete() from the corresponding freeze_late event handler.

If we build the workaround list in ring initialization and decouple it from the actual writing of values, we gain the ability to decide where and how we want to apply the values.

Too many new drm driver writers seem to look at i915 for inspiration. But we have two ways to do mmap, so discourage readers from the old, ugly version.
