drm/amd/display: Fix hang when skipping modeset

2023-05-17T12:02:08+00:00

commit da5e14909776edea4462672fb4a3007802d262e7 upstream. [Why&How] When skipping full modeset since the only state change was a front porch change, the DC commit sequence requires extra checks to handle non existant plane states being asked to be removed from context.

spi: fsl-cpm: Use 16 bit mode for large transfers with even size

2023-05-17T12:02:08+00:00

commit fc96ec826bced75cc6b9c07a4ac44bbf651337ab upstream. On CPM, the RISC core is a lot more efficiant when doing transfers in 16-bits chunks than in 8-bits chunks, but unfortunately the words need to be byte swapped as seen in a previous commit. So, for large tranfers with an even size, allocate a temporary tx buffer and byte-swap data before and after transfer. This change allows setting higher speed for transfer. For instance on an MPC 8xx (CPM1 comms RISC processor), the documentation tells that transfer in byte mode at 1 kbit/s uses 0.200% of CPM load at 25 MHz while a word transfer at the same speed uses 0.032% of CPM load. This means the speed can be 6 times higher in word mode for the same CPM load. For the time being, only do it on CPM1 as there must be a trade-off between the CPM load reduction and the CPU load required to byte swap the data.

spi: fsl-spi: Re-organise transfer bits_per_word adaptation

2023-05-17T12:02:08+00:00

commit 8a5299a1278eadf1e08a598a5345c376206f171e upstream. For different reasons, fsl-spi driver performs bits_per_word modifications for different reasons: - On CPU mode, to minimise amount of interrupts - On CPM/QE mode to work around controller byte order For CPU mode that's done in fsl_spi_prepare_message() while for CPM mode that's done in fsl_spi_setup_transfer(). Reunify all of it in fsl_spi_prepare_message(), and catch impossible cases early through master's bits_per_word_mask instead of returning EINVAL later.

drm/i915: disable sampler indirect state in bindless heap

2023-05-17T12:02:05+00:00

[ Upstream commit 81900e3a37750d8c6ad705045310e002f6dd0356 ] By default the indirect state sampler data (border colors) are stored in the same heap as the SAMPLER_STATE structure. For userspace drivers that can be 2 different heaps (dynamic state heap & bindless sampler state heap). This means that border colors have to copied in 2 different places so that the same SAMPLER_STATE structure find the right data. This change is forcing the indirect state sampler data to only be in the dynamic state pool (more convenient for userspace drivers, they only have to have one copy of the border colors). This is reproducing the behavior of the Windows drivers.

drm/i915: Add _PICK_EVEN_2RANGES()

2023-05-17T12:02:04+00:00

[ Upstream commit 357513233d6456c9f99e34794897efd4ae907e83 ] It's a constant pattern in the driver to need to use 2 ranges of MMIOs based on port, phy, pll, etc. When that happens, instead of using _PICK_EVEN(), _PICK() needs to be used. Using _PICK() is discouraged due to some reasons like: 1) It increases the code size since the array is declared in each call site 2) Developers need to be careful not to incur an out-of-bounds array access 3) Developers need to be careful that the indexes match the table. For that it may be that the table needs to contain holes, making (1) even worse. Add a variant of _PICK_EVEN() that works with 2 ranges and selects which one to use depending on the index value. v2: Fix the address expansion in the example (Anusha) v3: Also rename macro to _PICK_EVEN_2RANGES() in the documentation and reword it to clarify what ranges are chosen based on the index (Jani) Signed-off-by: Lucas De Marchi Reviewed-by: Anusha Srivatsa Acked-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20230125182403.7526-1-lucas.demarchi@intel.com Stable-dep-of: 214b09db6197 ("drm/msm: fix drm device leak on bind errors") Signed-off-by: Sasha Levin
