drm/i915/pfit: Extract intel_pfit.c

2024-10-23T15:22:37+00:00

The panel fitter code doesn't really have much to do with the
rest of intel_panel.c, so extract it all into its own file.

Merge drm/drm-next into drm-intel-next

2024-10-17T16:52:05+00:00

Needed to bring some KVM changes to be able to include a fix in our Kconfig.

drm/xe/guc: Prepare GuC register list and update ADS size for error capture

2024-10-08T16:34:04+00:00

Add referenced registers defines and list of registers.
Update GuC ADS size allocation to include space for
the lists of error state capture register descriptors.

Then, populate GuC ADS with the lists of registers we want
GuC to report back to host on engine reset events. This list
should include global, engine-class and engine-instance
registers for every engine-class type on the current hardware.

Ensure we allocate a persistent storage for the register lists
that are populated into ADS so that we don't need to allocate
memory during GT resets when GuC is reloaded and ADS population
happens again.

drm/i915/bios: Extract soc/intel_rom.c

2024-10-01T14:30:58+00:00

Abstract away the nuts and bolts of the SPI vs. PCI ROM
stuff, and hide it all in soc/intel_rom.c so that the
VBT code doesn't have to care about this stuff.

This leaves intel_bios.c with a single codepath that
can focus on the details related to the VBT layout.

This should have no functional changes.

v2: Rebase due to vbt_signature changes
    Drop unnecessary cast (Jani)

drm/i915/dp: split out intel_dp_test.[ch] to a dedicated file

2024-09-23T06:54:15+00:00

intel_dp.c has become huge, over 7k lines. Split out the fairly well
isolated chunk of DP test code to a dedicated file intel_dp_test.[ch].

drm/xe: eradicate -Ddrm_i915_gem_object=xe_bo

2024-09-19T13:37:21+00:00

We've now completely stopped using drm_i915_gem_object in display code
that gets built for xe. Kill off the -Ddrm_i915_gem_object=xe_bo
hack. Good riddance.

drm/i915/display: start a buffer object abstraction layer

2024-09-19T13:18:35+00:00

The display code needs to deal with gem objects, and mostly uses struct
drm_i915_gem_object. That's not great, because for xe we need to
redefine it struct xe_bo during build.

Start a common interface using struct drm_gem_object, with separate
implementations for i915 and xe. For starters, convert i9xx_wm.c to use
it.

drm/xe/pf: Add functions to save and restore VF GuC state

2024-09-16T11:00:22+00:00

To successfully migrate a VM with attached GPU VF we also need to
migrate VF's GuC state. Add necessary functions that interacts with
GuC to save and restore a VF GuC state. We will start using them in
upcoming patches.

Since VF migration requires many more changes in the driver, enable
those functions only under debug config.

drm/xe/hw_engine_group: Introduce xe_hw_engine_group

2024-08-18T01:31:47+00:00

A xe_hw_engine_group is a group of hw engines. Two hw engines belong to
the same xe_hw_engine_group if one hw engine cannot make progress while
the other is stuck on a page fault.

Typically, hw engines of the same group share some resources such as EUs,
but this really depends on the hardware configuration of the platforms.
The simple engines partitioning proposed here might be too conservative
but is intended to work for existing platforms. It can be optimized later
if more sets of independent engines are identified.

The hw engine groups are intended to be used in the context of faulting
long-running jobs submissions.

v2: Move to own files, improve error handling (Matt Brost)
