This reverts commit 1f61f065. Now we are supporting selective fetch for biplanar formats. We can revert WA patch which forced using full fetch for biplanar formats. Signed-off-by:

Biplanar formats are using two planes (Y and UV). This patch adds handling of Y selective fetch area by utilizing existing linked plane mechanism. Also UV plane Y offset configuration is modified according to Bspec. Signed-off-by:

By using the modifier plane capability flags to encode the modifiers' CCS type and tiling attributes, it becomes simpler to the check for any of these capabilities when providing the list of supported modifiers. This also allows distinguishing modifiers on future platforms where platforms with the same display version support different modifiers. An example is DG2 and ADLP, both being D13, where DG2 supports only F and X tiling, while ADLP supports only Y and X tiling. With the INTEL_PLANE_CAP_TILING_* flags added in this patch we can provide the correct modifiers for each platform. v2: - Define PLANE_HAS_* with macros instead of an enum. (Jani) - Rename PLANE_HAS_*_ANY to PLANE_HAS_*_MASK. (Jani) - Rename PLANE_HAS_* to INTEL_PLANE_CAP_*. - Set the CCS_RC_CC cap only for DISPLAY_VER >= 12. - Set the TILING_Y cap only for DISPLAY_VER < 13 || ADLP. - Simplify the SKL plane cap display version checks and move them to a separate function.

Our lane power down defines already include the necessary shift, don't shift them a second time. Fortunately we masked off the correct bits, so we accidentally left all lanes powered up all the time. Bits 8-11 where we end up writing our misdirected lane mask are documented as MBZ, but looks like you can actually write there so they're not read only bits. No idea what side effect the bogus register write might have. Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/4151Signed-off-by:

Looks like we never updated intel_bios_is_port_dp_dual_mode() when the VBT port mapping became erratic on modern platforms. This is causing us to look up the wrong child device and thus throwing the heuristic off (ie. we might end looking at a child device for a genuine DP++ port when we were supposed to look at one for a native HDMI port). Fix it up by not using the outdated port_mapping[] in intel_bios_is_port_dp_dual_mode() and rely on intel_bios_encoder_data_lookup() instead. Cc: stable@vger.kernel.org Tested-by:

Add FourCCs for 10- and 12-bit red formats with padding to 16 bits. They correspond to the V4L2 10- and 12-bit greyscale (V4L2_PIX_FMT_Y10 and V4L2_PIX_FMT_Y12) formats, as well as the Bayer formats with the same bit depth (V4L2_PIX_FMT_SBGGR{10,12} and all other Bayer pattern permutations). These formats are not used by any kernel driver at this point, but need to be exposed to applications by libcamera, which uses DRM FourCCs for pixel formats.

Now that the bigjoiner state readout/computation has been made to do the right thing nuke the related state checker quirk. Reviewed-by:

Ville Syrjälä authored
Try to make bigjoiner pipes less special. The main things here are that each pipe now does full clock computation/readout with its own shared_dpll reference. Also every pipe's cpu_transcoder always points correctly at the master transcoder. Due to the above changes state readout is now complete and all the related hacks can go away. The actual modeset sequence code is still a mess, but I think in order to clean that up properly we're probably going to have to redesign the modeset logic to treat transcoders vs. pipes separately. That is going to require significant amounts of work. Reviewed-by:

Let's disable planes on all pipes affected by the modeset before we start doing the actual modeset. This means we have less random planes enabled during the modeset, and it also mirrors what we already do when enabling pipes on skl+ since we enable planes on all pipes as the very last step. As a bonus we also nuke a bunch og bigjoiner special casing. I've occasionally pondered about going even furher here and doing the pre_plane_update() stuff for all pipes first, then actually disabling the planes, and finally running the rest of the modeset sequence. This would potentially allow parallelizing all the extra vblank waits across multiple pipes, and would make the plane disable even more atomic. But let's go one step a time here.

Disabling planes in the middle of the modeset seuqnece does not make sense since userspace can anyway disable planes before the modeset even starts. So when the modeset seuqence starts the set of enabled planes is entirely arbitrary. Trying to sprinkle the plane disabling into the modeset sequence just means more randomness and potential for hard to reproduce bugs. So it makes most sense to just disable all planes first so that the rest of the modeset sequence remains identical regardless of which planes happen to be enabled by userspace at the time. This reverts commit 84030adb. Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by:

Ville Syrjälä authored
PSR2 apparently requires some planes to be enabled for some silly reason, and so we are now trying to turn PSR off before planes go off. Except during a full modeset that is handled less clearly through reorganization of the modeset sequence. That is not great as it makes the code mode complex, and prevents us from doing nice things such as just turning off all the planes at the very start of the modeset. So let's move the PSR pre_plane_update() thing to a spot where it will handle both full modesets and everything else. Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by:

Alderlake-P was getting 'max time under evasion' messages when PSR2 is enabled, this is due PIPE_SCANLINE/PIPEDSL returning 0 over a period of time longer than VBLANK_EVASION_TIME_US. For PSR1 we had the same issue so intel_psr_wait_for_idle() was implemented to wait for PSR1 to get into idle state but nothing was done for PSR2. For PSR2 we can't only wait for idle state as PSR2 tends to keep into sleep state(ready to send selective updates). Waiting for any state below deep sleep proved to be effective in avoiding the evasion messages and also not wasted a lot of time. v2: - dropping the additional wait_for loops, only the _wait_for_atomic() is necessary - waiting for states below EDP_PSR2_STATUS_STATE_DEEP_SLEEP v3: - dropping intel_wait_for_condition_atomic() function Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Signed-off-by:

Commit 11086054 ("mm/secretmem: use refcount_t instead of atomic_t") attempted to fix the problem of secretmem_users wrapping to zero and allowing suspend once again. But it was reverted in commit 87066fdd ("Revert 'mm/secretmem: use refcount_t instead of atomic_t'") because of the problems it caused - a refcount_t was not semantically the right type to use. Instead prevent secretmem_users from wrapping to zero by forbidding new users if the number of users has wrapped from positive to negative. This stops a long way short of reaching the necessary 4 billion users where it wraps to zero again, so there's no need to be clever with special anti-wrap types or checking the return value from atomic_inc().

Commit efafec27 ("spi: Fix tegra20 build with CONFIG_PM=n") already fixed the build without PM support once. There was an alternative fix by Guenter in commit 2bab9409 ("spi: tegra20-slink: Declare runtime suspend and resume functions conditionally"), and Mark then merged the two correctly in ffb1e76f ("Merge tag 'v5.15-rc2' into spi-5.15"). But for some inexplicable reason, Mark then merged things _again_ in commit 59c4e190 ("Merge tag 'v5.15-rc3' into spi-5.15"), and screwed things up at that point, and the __maybe_unused attribute on tegra_slink_runtime_resume() went missing. Reinstate it, so that alpha (and other architectures without PM support) builds cleanly again. Btw, this is another prime example of how random back-merges are not good. Just don't do them. Subsystem developers should not merge my tree in any normal circumstances. Both of those merge commits pointed to above are bad: even the one that got the merge result right doesn't even mention _why_ it was done, and the one that got it wrong is obviously broken.
