2024-08-14drm/xe: Move enable host l2 VRAM post MCR initTejas Upadhyay1-1/+1
xe_gt_enable_host_l2_vram() is reading the XE2_GAMREQSTRM_CTRL register that is currently missing the MCR annotation. However, just adding the annotation doesn't work as this function is called before MCR handling is initialized in xe_gt_mcr_init(). xe_gt_enable_host_l2_vram() is used to implement WA 16023588340 that needs to be done as early as possible during initialization in order to be effective since the MMIO writes impact it. In the failure scenario, driver would simply not be able to bind successfully. Moving xe_gt_enable_host_l2_vram() later, after MCR initialization is done, only incurs a few additional HW accesses, particularly when loading GuC for hwconfig. Binding/unbinding the driver 100 times in BMG still works so it should be ok to start handling the WA a little bit later. This is sufficient to allow adding the MCR annotation to XE2_GAMREQSTRM_CTRL.

2024-08-14spi: spi-cadence-quadspi: Fix OSPI NOR failures during system resumeVignesh Raghavendra1-1/+13
Its necessary to call pm_runtime_force_*() hooks as part of system suspend/resume calls so that the runtime_pm hooks get called. This ensures latest state of the IP is cached and restored during system sleep. This is especially true if runtime autosuspend is enabled as runtime suspend hooks may not be called at all before system sleeps. Without this patch, OSPI NOR enumeration (READ_ID) fails during resume as context saved during suspend path is inconsistent.

2024-08-14Revert "ata: libata-scsi: Honor the D_SENSE bit for CK_COND=1 and no error"Niklas Cassel1-2/+13
This reverts commit 28ab9769117ca944cb6eb537af5599aa436287a4. Sense data can be in either fixed format or descriptor format. SAT-6 revision 1, "10.4.6 Control mode page", defines the D_SENSE bit: "The SATL shall support this bit as defined in SPC-5 with the following exception: if the D_ SENSE bit is set to zero (i.e., fixed format sense data), then the SATL should return fixed format sense data for ATA PASS-THROUGH commands." The libata SATL has always kept D_SENSE set to zero by default. (It is however possible to change the value using a MODE SELECT SG_IO command.) Failed ATA PASS-THROUGH commands correctly respected the D_SENSE bit, however, successful ATA PASS-THROUGH commands incorrectly returned the sense data in descriptor format (regardless of the D_SENSE bit). Commit 28ab9769117c ("ata: libata-scsi: Honor the D_SENSE bit for CK_COND=1 and no error") fixed this bug for successful ATA PASS-THROUGH commands. However, after commit 28ab9769117c ("ata: libata-scsi: Honor the D_SENSE bit for CK_COND=1 and no error"), there were bug reports that hdparm, hddtemp, and udisks were no longer working as expected. These applications incorrectly assume the returned sense data is in descriptor format, without even looking at the RESPONSE CODE field in the returned sense data (to see which format the returned sense data is in). Considering that there will be broken versions of these applications around roughly forever, we are stuck with being bug compatible with older kernels.

2024-08-14drm/i915/gvt: stop using drm_edid_block_valid()Jani Nikula1-5/+13
We'll want to stop drm_edid_block_valid() usage. KVMGT is the last user. Replace with drm_edid_valid(), which unfortunately requires an allocated drm_edid. However, on the plus side, this would be required to handle the TODO comment about EDID extension block support.

2024-08-14media: videobuf2-core: attach once if multiple planes share the same dbufYunke Cao1-4/+26
When multiple planes use the same dma buf, each plane will have its own dma buf attachment and mapping. It is a waste of IOVA space. This patch adds a dbuf_duplicated boolean in vb2_plane. If a plane's dbuf is the same as an existing plane, do not create another attachment and mapping.

2024-08-14media: videobuf2-core: reverse the iteration order in __vb2_buf_dmabuf_putYunke Cao1-2/+8
This patch prepares for allowing multiple planes to share the same DMA buffer attachment. Release the planes from num_planes - 1 to 0 so that we don't leave invalid mem_priv pointers behind.

2024-08-14media: videobuf2-core: release all planes first in __prepare_dmabuf()Yunke Cao1-56/+59
In the existing implementation, validating planes, checking if the planes changed, releasing previous planes and reaquiring new planes all happens in the same for loop. Split the for loop into 3 parts 1. In the first for loop, validate planes and check if planes changed. 2. Call __vb2_buf_dmabuf_put() to release all planes. 3. In the second for loop, reaquire new planes. Signed-off-by: Yunke Cao <[email protected]> Acked-by: Tomasz Figa <[email protected]> Signed-off-by: Hans Verkuil <[email protected]>

Clear vb2_plane's memory related fields in __vb2_plane_dmabuf_put(), including bytesused, length, fd and data_offset. Remove the duplicated code in __prepare_dmabuf().

2024-08-14media: mgb4: Fixed signal frame rate limit handlingMartin Tůma3-11/+12
Change the default DV timings for the outputs to produce a better signal less "crippled" by the frame rate limiting. While the individual values are now different, the resulting signal still matches the same default display as before. Additionally fix the corner case when the frame rate limit is set to zero causing a "divide by zero" kernel panic.
