The SDE interrupt bits 25, 26 and 27 are either reserved or meant for DDI E hotplug in SPT+. These bits are meant for AUX channels only in LPT and CPT, so add the appropriate checks.

Min brightness value from vbt was missing for BXT platform. This setting have to refer backlight ic spec to restrict min backlight output.

During IGT testing it has been shown that the specification defined polling time of 1 us for FCLK_DONE, is sometimes not enough. The issue is still reproducible while disabling C-states through the PM QoS framework and also while disabling preemtion. From this the most plausible explanation is that the issue is due to a firmware flaw. As a workaround, it is better to wait a little bit longer for the FCLK_DONE to come around, than to leave with an DRM_ERROR and having FCLK_DONE at a randome time after. While spinning a list of igt tests prone to reproduce the issue the FCLK_DONE poll failed at approximately 2% of the invocations of the bdw_set_cdclk function. The longest poll time during this testing was measured to ~7us. So, the suggested new poll time of 100us is on the safe side. v2: Added more documentation about investigations done.

No functional change is expected here since at this point PSR is not allowed to go to any active state. In other words, not really enabled. However let's do in a separated patch so it gets clear on what is change and specially it can helps on bisect case if we figure something has caused changes in behaviour. But this needs to be done before we make the vfunc to enable source to be in parity with VLV implementation.

Chris Wilson authored
If we know that we will completely fill a pagetable (i.e. we are inserting a complete set of 512 pages), we can skip prefilling that PT with scratch entries. If we have to abort the insertion prior to writing the real entries, we will teardown the pagetable and remove it from the page directory (so that we will restart the allocation next time). We could do similar tricks for the PD and PDP, but the likelihood of a single insertion covering the entire 512 entries diminishes, as do the cycle savings. The saving are even greater (relatively) when we are preallocating page tables for huge pages, as then we never need to fill the page table.

Currently, we only emulate the PCI compatible Configuration Space. This is okay if we attach vGPU to PCI bus. But when we attach to a PCI Express bus (when Qemu emulates a Intel Q35 chipset which has PCIe slot), it will not work. Extended Configuration Space is required for a PCIe device. This patch extended the virtual configuration space from 256 bytes to 4KB bytes. So we are to be a *real* PCIe device. And for the Extended CapList we keep same to physical GPU.

Looking at our virtual PCI device, we can see surprising Region 4 and Region 5. 00:10.0 VGA compatible controller: Intel Corporation Sky Lake Integrated Graphics (rev 06) (prog-if 00 [VGA controller]) .... Region 0: Memory at 140000000 (64-bit, non-prefetchable) [size=16M] Region 2: Memory at 180000000 (64-bit, prefetchable) [size=1G] Region 4: Memory at <ignored> (32-bit, non-prefetchable) Region 5: Memory at <ignored> (32-bit, non-prefetchable) Expansion ROM at febd6000 [disabled] [size=2K] The fact is that we only implemented BAR0 and BAR2. Surprising Region 4 and Region 5 are shown because we report their size as 0xffffffff. They should report size 0 instead. BTW, the physical GPU has a PIO BAR. GVTg hasn't implemented PIO access, so we ignored this BAR for vGPU device. v2: fix BAR size value calculation.

Currently i915 request structure and shadow ring buffer are allocated before command scan, so it will have to restore to previous states once any error happens afterwards in the long dispatch_workload path. This patch is to introduce a reserved ring buffer created at the beginning of vGPU initialization. Workload will be coped to this reserved buffer and be scanned first, the i915 request and shadow ring buffer are only allocated after the result of scan is successful. To balance the memory usage and buffer alloc time, the coming bigger ring buffer will be reallocated and kept until more bigger buffer is coming. v2: - use kmalloc for the smaller ring buffer, realloc if required. (Zhenyu) v3: - remove the dynamically allocated ring buffer. (Zhenyu) v4: - code style polish. - kfree previous allocated buffer once kmalloc failed.

For vfio-pci, if the region support MMAP then it should support both mmap and normal file access. The user-space is free to choose which is being used. For qemu, we just need add 'x-no-mmap=on' for vfio-pci option. Currently GVTg only support MMAP for BAR2. So GVTg will not work when user turn on x-no-mmap option. This patch added file style access for BAR2, aka the GPU aperture. We map the entire aperture partition of active vGPU to kernel space when guest driver try to enable PCI Memory Space. Then we redirect the file RW operation from kvmgt to this mapped area.

Afaict, GEN9_GAMT_ECO_REG_RW_IA does not live in the context, so writing it on every context creation is overkill (and wrong). v2: Missing end parenthesis Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: Mika Kuoppala <mika.kuoppala@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Oscar Mateo <oscar.mateo@intel.com> Reviewed-by: Michał Winiarski <michal.winiarski@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/1504798809-5653-1-git-send-email-oscar.mateo@intel.comSigned-off-by: Chris Wilson <chris@chris-wilson.co.uk>

We also see the delayed GTT write issue on i915g/i915gm, so let's presume that it is a universal problem for all !llc machines, and that we just haven't yet noticed on g33, gen4 and gen5 machines. v2: Use a register that exists on all platforms Testcase: igt/gem_mmap_gtt/coherency # i915gm References: https://bugs.freedesktop.org/show_bug.cgi?id=102577Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20170907184520.5032-1-chris@chris-wilson.co.ukReviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com>

drm_pci_alloc() refuses to cooperate if the passed alignment exceeds the object size. So round up the obj size to the next power of two as well to make this actually work. Obviously things work just fine as long as the size was a power of two to begin with. However kms_cursor_crc doesn't always use power of two sizes so we hit a failure when we try to allocate the phys memory.
