2024-08-26drm/i915: ARL requires a newer GSC firmwareJohn Harrison1-0/+7
ARL and MTL share a single GSC firmware blob. However, ARL requires a newer version of it. So add differentiate of the PCI ids for ARL from MTL and create ARL as a sub-platform of MTL. That way, all the existing workarounds and such still treat ARL as MTL exactly as before. However, now the GSC code can check for ARL and do an extra version check on the firmware before committing to it. Also, the version extraction code has various ways of failing but the return code was being ignore and so the firmware load would attempt to continue anyway. Fix that by propagating the return code to the next level out.

Move the stepping related macros over to display. We can proceed to remove the compat macros from xe. Note: Looks like we've failed to actually initialize the display stepping for GMD ID based platforms in the xe driver. It does get set in display runtime info, but until now the compat macro used xe->info.step.display which was not set for GMD ID.

2023-08-21drm/i915/mtl: Eliminate subplatformsMatt Roper1-14/+0
Now that we properly match the Xe_LPG IP versions associated with various workarounds, there's no longer any need to define separate MTL subplatform in the driver. Nothing in the code is conditional on MTL-M or MTL-P base platforms. Furthermore, I'm not sure the "M" and "P" designations are even an accurate representation of which specific platforms would have which IP versions; those were mostly just placeholders from a long time ago. The reality is that the IP version present on a platform gets read from a fuse register at driver init; we shouldn't be trying to guess which IP is present based on PCI ID anymore.

2023-05-24drm/i915/display: Handle GMD_ID identification in display codeMatt Roper1-4/+9
For platforms with GMD_ID support (i.e., everything MTL and beyond), identification of the display IP present should be based on the contents of the GMD_ID register rather than a PCI devid match. Note that since GMD_ID readout requires access to the PCI BAR, a slight change to the driver init sequence is needed --- pci_enable_device() is now called before i915_driver_create(). v2: - Fix use of uninitialized i915 pointer in error path if pci_enable_device() fails before the i915 device is created. (lkp) - Use drm_device parameter to intel_display_device_probe. This goes against i915 conventions, but since the primary goal here is to make it easy to call this function from other drivers (like Xe) and since we don't need anything from the i915 structure, this seems like an exception where drm_device is a more natural fit. v3: - Go back do drm_i915_private for intel_display_device_probe.

2023-04-14drm/i915: hide mkwrite_device_info() betterJani Nikula1-0/+29
The goal has been to just make device info a pointer to static const data, i.e. the static const structs in i915_pci.c. See [1]. However, there were issues with intel_device_info_runtime_init() clearing the display sub-struct of device info on the !HAS_DISPLAY() path, which consequently disables a lot of display functionality, like it should. Looks like we'd have to cover all those paths, and maybe sprinkle HAS_DISPLAY() checks in them, which we haven't gotten around to. In the mean time, hide mkwrite_device_info() better within intel_device_info.c by adding a intel_device_info_driver_create() for the very early initialization of the device info and initial runtime info. This also lets us declutter i915_drv.h a bit, and stops promoting mkwrite_device_info() as something that could be used.

2023-01-25drm/i915/display: add intel_display_limits.h for key enumsJani Nikula1-0/+1
Move a handful of key enums to a new file intel_display_limits.h. These are the enum types, and the MAX/NUM enumerations within them, that are used in other headers. Otherwise, there's no common theme between them. Replace intel_display.h include with intel_display_limit.h where relevant, and add the intel_display.h include directly in the .c files where needed. Since intel_display.h is used almost everywhere in display/, include it from intel_display_types.h to avoid massive changes across the board. There are very few files that would need intel_display_types.h but not intel_display.h so this is neglible, and further cleanup between these headers can be left for the future. Overall this change drops the direct and indirect dependencies on intel_display.h from about 300 to about 100 compilation units, because we can drop the include from i915_drv.h.

2022-11-11drm/i915: stop including i915_irq.h from i915_trace.hJani Nikula1-1/+2
Turns out many of the files that need i915_reg.h get it implicitly via {display/intel_de.h, gt/intel_context.h} -> i915_trace.h -> i915_irq.h -> i915_reg.h. Since i915_trace.h doesn't actually need i915_irq.h, makes sense to drop it, but that requires adding quite a few new includes all over the place. Prefer including i915_reg.h where needed instead of adding another implicit include, because eventually we'll want to split up i915_reg.h and only include the specific registers at each place. Also some places actually needed i915_irq.h too.

Currently we do the DRIVER_ATOMIC disable as almost the first thing during pci probe. That involves the use of DISPLAY_VER() which is perhaps a bit sketchy now that we may need to read that out from the hardware itself. Looks like we do populate a default value for it anyway so the current does at least still work. But let's make this safer anyway and move the code into intel_device_info_runtime_init() where we also handle the same thing for the !HAS_DISPLAY case.

2022-09-26drm/i915: fix device info for devices without displayJani Nikula1-0/+6
Commit 00c6cbfd4e8a ("drm/i915: move pipe_mask and cpu_transcoder_mask to runtime info") moved the pipe_mask member from struct intel_device_info to intel_runtime_info, but overlooked some of our platforms initializing device info .display = {}. This is significant, as pipe_mask is the single point of truth for a device having a display or not; the platforms in question left pipe_mask to whatever was set for the platforms they "inherit" from in the complex macro scheme we have. Add new NO_DISPLAY macro initializing .__runtime.pipe_mask = 0, which will cause the device info .display sub-struct to be zeroed in intel_device_info_runtime_init(). A better solution (or simply audit of proper use of HAS_DISPLAY() checks) is required before moving forward with [1]. Also clear all the display related members in runtime info if there's no display. The latter is a bit tedious, but it's for completeness at this time, to ensure similar functionality as before.
