2024-04-14drm/i915/guc: Remove usage of the deprecated ida_simple_xx() APIChristophe JAILLET
ida_alloc() and ida_free() should be preferred to the deprecated ida_simple_get() and ida_simple_remove(). Note that the upper limit of ida_simple_get() is exclusive, but the one of ida_alloc_range() is inclusive. So a -1 has been added when needed.

2024-04-12drm/xe: Use hmm_range_fault to populate user pagesOak Zeng
This is an effort to unify hmmptr (aka system allocator) and userptr code. hmm_range_fault is used to populate a virtual address range for both hmmptr and userptr, instead of hmmptr using hmm_range_fault and userptr using get_user_pages_fast. This also aligns with AMD gpu driver's behavior. In long term, we plan to put some common helpers in this area to drm layer so it can be re-used by different vendors. -v1 use the function with parameter to confirm whether lock is acquired by the caller or needs to be acquired in hmm_range_fault.

Advertize more suitable cursor sizes via the new SIZE_HINTS plane property. We can't really enumerate all supported cursor sizes on the platforms where the cursor height can vary freely, so for simplicity we'll just expose all square+POT sizes between each platform's min and max cursor limits. Depending on the platform this will give us one of three results: - 64x64,128x128,256x256,512x512 - 64x64,128x128,256x256 - 64x64 Cc: Simon Ser <contact@emersion.fr> Cc: Jonas Ådahl <jadahl@redhat.com> Cc: Daniel Stone <daniel@fooishbar.org> Cc: Sameer Lattannavar <sameer.lattannavar@intel.com> Cc: Sebastian Wick <sebastian.wick@redhat.com> Cc: Harry Wentland <harry.wentland@amd.com> Cc: Pekka Paalanen <pekka.paalanen@collabora.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240318204408.9687-3-ville.syrjala@linux.intel.com Reviewed-by: Juha-Pekka Heikkila <juhapekka.heikkila@gmail.com>
2024-04-11drm: Introduce plane SIZE_HINTS propertyVille Syrjälä
Add a new immutable plane property by which a plane can advertise a handful of recommended plane sizes. This would be mostly exposed by cursor planes as a slightly more capable replacement for the DRM_CAP_CURSOR_WIDTH/HEIGHT caps, which can only declare a one size fits all limit for the whole device. Currently eg. amdgpu/i915/nouveau just advertize the max cursor size via the cursor size caps. But always using the max sized cursor can waste a surprising amount of power, so a better strategy is desirable. Most other drivers don't specify any cursor size at all, in which case the ioctl code just claims that 64x64 is a great choice. Whether that is actually true is debatable. A poll of various compositor developers informs us that blindly probing with setcursor/atomic ioctl to determine suitable cursor sizes is not acceptable, thus the introduction of the new property to supplant the cursor size caps. The compositor will now be free to select a more optimal cursor size from the short list of options. Note that the reported sizes (either via the property or the caps) make no claims about things such as plane scaling. So these things should only really be consulted for simple "cursor like" use cases.

2024-04-11treewide: Use sysfs_bin_attr_simple_read() helperLukas Wunner
Deduplicate ->read() callbacks of bin_attributes which are backed by a simple buffer in memory: Use the newly introduced sysfs_bin_attr_simple_read() helper instead, either by referencing it directly or by declaring such bin_attributes with BIN_ATTR_SIMPLE_RO() or BIN_ATTR_SIMPLE_ADMIN_RO(). Aside from a reduction of LoC, this shaves off a few bytes from vmlinux (304 bytes on an x86_64 allyesconfig). No functional change intended.
