2024-02-01media: atomisp: Drop is_valid_device() functionHans de Goede
Now that a single build supports both the ISP 2400 and the ISP 2401 this function is no longer necessary. The main probe() already contains a similar switch (id->device & ATOMISP_PCI_DEVICE_SOC_MASK) checking for a known device_id. Move the revision check into the main probe() and drop the is_valid_device() function. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
2024-02-01media: atomisp: Remove remaining deferred firmware loading codeHans de Goede
There is a bunch of dead code left from the deferred firmware loading support which was removed in commit 8972ed6ea7a0 ("media: atomisp: Remove deferred firmware loading support"). Remove this dead code: - Remove the skip_fwload module parameter - Remove the now always NULL fw argument from ia_css_init() - Remove the fw_explicitly_loaded boolean from sh_css.c (this was always true now) - Adjust some function kernel-doc comments to match Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
2024-02-01media: atomisp: Remove s_routing subdev callHans de Goede
sensor drivers do not implement the s_routing subdev call, so there is no use in calling it. Also the 3 0 arguments are not the arguments which a successful s_routing call is supposed to take.

2024-02-01media: atomisp: Refactor sensor crop + fmt settingHans de Goede
There are 3 code-paths all of 3 which need to do: 1. Get try or active state 2. lock state 3. Call atomisp_set_crop() 4. Call v4l2_subdev_call(input->camera, pad, set_fmt, state, fmt) 5. unlock state Change atomisp_set_crop into atomisp_set_crop_and_fmt() which does all of this and change the 3 code-paths which need this to use the new atomisp_set_crop_and_fmt() function.

2024-02-01media: atomisp: Adjust for v4l2_subdev_state handling changes in 6.8Hans de Goede
The atomisp driver emulates a standard v4l2 device, which also works for non media-controller aware applications. Part of this requires making try_fmt calls on the sensor when a normal v4l2 app is making try_fmt calls on the /dev/video# mode. With the recent v4l2_subdev_state handling changes in 6.8 this no longer works, fixing this requires 2 changes: 1. The atomisp code was using its own internal v4l2_subdev_pad_config for this. Replace the internal v4l2_subdev_pad_config with allocating a full v4l2_subdev_state for storing the full try_fmt state. 2. The paths actually setting the fmt or crop selection now need to be passed the v4l2_subdev's active state, so that sensor drivers which are using the v4l2_subdev's active state to store their state keep working.

2024-01-27mips: Call lose_fpu(0) before initializing fcr31 in mips_set_personality_nanXi Ruoyao
If we still own the FPU after initializing fcr31, when we are preempted the dirty value in the FPU will be read out and stored into fcr31, clobbering our setting. This can cause an improper floating-point environment after execve(). For example: zsh% cat measure.c #include <fenv.h> int main() { return fetestexcept(FE_INEXACT); } zsh% cc measure.c -o measure -lm zsh% echo $((1.0/3)) # raising FE_INEXACT 0.33333333333333331 zsh% while ./measure; do ; done (stopped in seconds) Call lose_fpu(0) before setting fcr31 to prevent this.

git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux Pull ata updates from Niklas Cassel: - Fix an incorrect link_power_management_policy sysfs attribute value. We were previously using the same attribute value for two different LPM policies (me) - Add a ASMedia ASM1166 quirk. The SATA host controller always reports that it has 32 ports, even though it only has six ports. Add a quirk that overrides the value reported by the controller (Conrad) - Add a ASMedia ASM1061 quirk. The SATA host controller completely ignores the upper 21 bits of the DMA address. This causes IOMMU error events when a (valid) DMA address actually has any of the upper 21 bits set. Add a quirk that limits the dma_mask to 43-bits (Lennert) * tag 'ata-6.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux: ahci: add 43-bit DMA address quirk for ASMedia ASM1061 controllers ahci: asm1166: correct count of reported ports ata: libata-sata: improve sysfs description for ATA_LPM_UNKNOWN

Pull drm fixes from Dave Airlie: "Lots going on for rc2, ivpu has a bunch of stabilisation and debugging work, then amdgpu and xe are the main fixes. i915, exynos have a few, then some misc panel and bridge fixes. Worth mentioning are three regressions. One of the nouveau fixes in 6.7 for a serious deadlock had side effects, so I guess we will bring back the deadlock until I can figure out what should be done properly. There was a scheduler regression vs amdgpu which was reported in a few places and is now fixed. There was an i915 vs simpledrm problem resulting in black screens, that is reverted also. I'll be working on a proper nouveau fix, it kinda looks like one of those cases where someone tried to use an atomic where they should have probably used a lock, but I'll see. fb: - fix simpledrm/i915 regression by reverting change scheduler: - fix regression affecting amdgpu users due to sched draining nouveau: - revert 6.7 deadlock fix as it has side effects dp: - fix documentation warning ttm: - fix dummy page read on some platforms bridge: - anx7625 suspend fix - sii902x: fix probing and audio registration - parade-ps8640: fix suspend of bridge, aux fixes - samsung-dsim: avoid using FORCE_STOP_STATE panel: - simple add missing bus flags - fix samsung-s6d7aa0 flags amdgpu: - AC/DC power supply tracking fix - Don't show invalid vram vendor data - SMU 13.0.x fixes - GART fix for umr on systems without VRAM - GFX 10/11 UNORD_DISPATCH fixes - IPS display fixes (required for S0ix on some platforms) - Misc fixes i915: - DSI sequence revert to fix GitLab #10071 and DP test-pattern fix - Drop -Wstringop-overflow (broken on GCC11) ivpu: - fix recovery/reset support - improve submit ioctl stability - fix dev open/close races on unbind - PLL disable reset fix - deprecate context priority param - improve debug buffer logging - disable buffer sharing across VPU contexts - free buffer sgt on unbind - fix missing lock around shmem vmap - add better boot diagnostics - add more debug prints around mapping - dump MMU events in case of timeout v3d: - NULL ptr dereference fix exynos: - fix stack usage - fix incorrect type - fix dt typo - fix gsc runtime resume xe: - Make an ops struct static - Fix an implicit 0 to NULL conversion - A couple of 32-bit fixes - A migration coherency fix for Lunar Lake. - An error path vm id leak fix - Remove PVC references in kunit tests" * tag 'drm-fixes-2024-01-27' of git://anongit.freedesktop.org/drm/drm: (66 commits) Revert "nouveau: push event block/allowing out of the fence context" drm: bridge: samsung-dsim: Don't use FORCE_STOP_STATE drm/sched: Drain all entities in DRM sched run job worker drm/amd/display: "Enable IPS by default" drm/amd: Add a DC debug mask for IPS drm/amd/display: Disable ips before dc interrupt setting drm/amd/display: Replay + IPS + ABM in Full Screen VPB drm/amd/display: Add IPS checks before dcn register access drm/amd/display: Add Replay IPS register for DMUB command table drm/amd/display: Allow IPS2 during Replay drm/amdgpu/gfx11: set UNORD_DISPATCH in compute MQDs drm/amdgpu/gfx10: set UNORD_DISPATCH in compute MQDs drm/amd/amdgpu: Assign GART pages to AMD device mapping drm/amd/pm: Fetch current power limit from FW drm/amdgpu: Fix null pointer dereference drm/amdgpu: Show vram vendor only if available drm/amd/pm: update the power cap setting drm/amdgpu: Avoid fetching vram vendor information drm/amdgpu/pm: Fix the power source flag error drm/amd/display: Fix uninitialized variable usage in core_link_ 'read_dpcd() & write_dpcd()' functions ...
