2021-11-17drm/i915/driver: rename i915_drv.c to i915_driver.cJani Nikula1-1834/+0
This is more about trimming i915_drv.h than the renamed i915_driver.[ch]. Split out i915_driver.[ch] out of i915_drv.h as a feasible thing to do.

2021-11-03drm/i915: Restore memory mapping for DPT FBs across system suspend/resumeImre Deak1-0/+5
At least during hibernation the DPT mappings are lost with all stolen memory content, so suspend/resume these mappings similarly to GGTT mappings. This fixes a problem where the restoring modeset during system resume fails with pipe faults if a tiled framebuffer was active before suspend. v2: Clarify the way restore works in intel_dpt_resume()'s Docbook entry.

2021-09-24drm/i915 Implement LMEM backup and restore for suspend / resumeThomas Hellström1-3/+1
Just evict unpinned objects to system. For pinned LMEM objects, make a backup system object and blit the contents to that. Backup is performed in three steps, 1: Opportunistically evict evictable objects using the gpu blitter. 2: After gt idle, evict evictable objects using the gpu blitter. This will be modified in an upcoming patch to backup pinned objects that are not used by the blitter itself. 3: Backup remaining pinned objects using memcpy. Also move uC suspend to after 2) to make sure we have a functional GuC during 2) if using GuC submission. v2: - Major refactor to make sure gem_exec_suspend@hang-SX subtests work, and suspend / resume works with a slightly modified GuC submission enabling patch series. v3: - Fix a potential use-after-free (Matthew Auld) - Use i915_gem_object_create_shmem() instead of i915_gem_object_create_region (Matthew Auld) - Minor simplifications (Matthew Auld) - Fix up kerneldoc for i195_ttm_restore_region(). - Final lmem_suspend() call moved to i915_gem_backup_suspend from i915_gem_suspend_late, since the latter gets called at driver unload and we don't unnecessarily want to run it at that time. v4: - Interface change of ttm- & lmem suspend / resume functions to use flags rather than bools.

UAPI Changes: - Add I915_MMAP_OFFSET_FIXED On devices with local memory `I915_MMAP_OFFSET_FIXED` is the only valid type. On devices without local memory, this caching mode is invalid. As caching mode when specifying `I915_MMAP_OFFSET_FIXED`, WC or WB will be used, depending on the object placement on creation. WB will be used when the object can only exist in system memory, WC otherwise. Userspace: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/11888 - Reinstate the mmap ioctl for (already released) integrated Gen12 platforms Rationale: Otherwise media driver breaks eg. for ADL-P. Long term goal is still to sunset the IOCTL even for integrated and require using mmap_offset. - Reject caching/set_domain IOCTLs on discrete Expected to become immutable property of the BO - Disallow changing context parameters after first use on Gen12 and earlier - Require setting context parameters at creation on platforms after Gen12 Rationale (for both): Allow less dynamic changes to the context to simplify the implementation and avoid user shooting theirselves in the foot. - Drop I915_CONTEXT_PARAM_RINGSIZE Userspace PR for compute-driver has not been merged - Drop I915_CONTEXT_PARAM_NO_ZEROMAP Userspace PR for libdrm / Beignet was never landed - Drop CONTEXT_CLONE API Userspace PR for Mesa was never landed - Drop getparam support for I915_CONTEXT_PARAM_ENGINES Only existed for symmetry wrt. setparam, never used. - Disallow bonding of virtual engines Drop the prep work, no hardware has been released needing it. - (Implicit) Disable gpu relocations Media userspace was the last userspace to still use them.

2021-07-28drm/i915: dgfx cards need to wait on pcode's uncore init doneBadal Nilawar1-1/+7
In discrete cards, the graphics driver shouldn't proceed with the probe or resume unless PCODE indicated everything is done, including memory training and gt bring up. For this reason, the driver probe and resume paths needs to be blocked until PCODE indicates it is done. Also, it needs to aborted if the notification never arrives. In general, the few miliseconds would be enough and the regular PCODE recommendation for the timeout was 10 seconds. However there are some rare cases where this initialization can take up to 1 minute. So, PCODE has increased the recommendation to 3 minutes so we don't fully block the device utilization when something just got delayed for whatever reason. To be on the safest side, let's accept this recommendation, since on the regular case it won't delay or block the driver initialization and resume flows Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Badal Nilawar <badal.nilawar@intel.com> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210727173338.901264-1-badal.nilawar@intel.com

2021-07-14drm/i915/icl: Use revid->stepping tablesMatt Roper1-0/+1
Switch ICL to use a revid->stepping table as we're trying to do on all platforms going forward. While we're at it, let's include some additional steppings that have popped up, even if we don't yet have any workarounds tied to those steppings (we probably need to audit our workaround list soon to see if any of the bounds have moved or if new workarounds have appeared). Note that the current bspec table is missing information about how to map PCI revision ID to GT/display steppings; it only provides an SoC stepping. The mapping to GT/display steppings (which aren't always the same as the SoC stepping) used to be in the bspec, but was apparently dropped during an update in Nov 2019; I've made my changes here based on an older bspec snapshot that still had the necessary information. We've requested that the missing information be restored. I'm only including the production revids in the table here since we're past the point at which we usually stop trying to support pre-production hardware.

This also fixes theoretical out of bounds access to kbl_revids array. v3: upgrade dbg to warn on unknown revid (José) v2: Rename stepping->step Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/79b6c48211c6b214165391d350d556bad748f747.1616764798.git.jani.nikula@intel.com
2021-03-24drm/i915: give stolen system memory its own classMatthew Auld1-1/+1
In some future patches we will need to also support a stolen region carved from device local memory, on platforms like DG1. To handle this we can simply describe each in terms of its own memory class.

2021-03-24drm/i915: make local-memory probing a GT operationMatthew Auld1-0/+4
Device local memory is very much a GT thing, therefore it should be the responsibility of the GT to setup the device local memory region.

2021-03-18drm/i915/gem: Drop legacy execbuffer support (v2)Jason Ekstrand1-1/+1
libdrm has supported the newer execbuffer2 ioctl and using it by default when it exists since libdrm commit b50964027bef which landed Mar 2, 2010. The i915 and i965 drivers in Mesa at the time both used libdrm and so did the Intel X11 back-end. The SNA back-end for X11 has always used execbuffer2. v2 (Jason Ekstrand): - Add a comment saying what Linux version it's being removed in.

2021-02-13drm/i915: move intel_init_audio_hooks inside displayLucas De Marchi1-2/+0
intel_init_audio_hooks() sets up hooks in the display struct and only makes sense when we have display. Move it inside intel_init_display_hooks() so it isn't called when we don't have display.

2021-02-13drm/i915/display: move register functions to display/Lucas De Marchi1-43/+2
Now that all display-related functions are grouped in i915_driver_register(), move them to display/ so we reduce the amount of display calls from the rest of the driver.

2021-02-13drm/i915: group display-related register callsLucas De Marchi1-30/+34
intel_gt_driver_register() may be called earlier than intel_opregion_register() and acpi_video_register(), so move it up. intel_display_debugfs_register() may be called later, together with the other display-related initializations. There is a slight change in behavior that sysfs files will show up before the display-related debugfs files, but that shouldn't be a problem - userspace shouldn't be relying in debugfs. This allows us to group all the display-related calls under a single check for "HAS_DISPLAY()" that can be later moved to a better place.
