Discussed with Noralf on the list a bit. An open question is tinydrm vs. drm_panel, but until we have a clear idea what's really needed in that space, I think it's best to just move forward with what we have. Cc: Noralf Trønnes <noralf@tronnes.org> Acked-by:

drm_dp_mst_allocate_vcpi() apart from setting up the vcpi structure, also finds if there are enough slots available. This check is a duplicate of that implemented in drm_dp_mst_find_vcpi_slots(). Let's move this check out and reuse the existing drm_dp_mst_find_vcpi_slots() function to check if there are enough vcpi slots before allocating them. This brings the check to one place. Additionally drivers that will use MST state tracking for atomic modesets can use the atomic version of find_vcpi_slots() and reuse drm_dp_mst_allocate_vcpi() Signed-off-by:

The total vcpi time slots is always 63 and does not depend on the link BW, remove total_slots from MST topology manager struct. The next change is to remove total_pbn which is hardcoded to 2560. The total PBN that the topology manager allocates from depends on the link rate and is not a constant. So, fix this by removing the total_pbn member itself.

Allow framebuffers dimesions to be misaligned w.r.t. the subsampling factors. No real reason the core should have to enforce this, and it definitely starts to cause us issues with the i915 CCS support. So let's just lift the restriction. Let's start to round up when computing the color plane dimesions so that we'll not end up with too low an estimate for the memory requirements and whatnot.

This patch does following: - Adds a new structure (drm_hdmi_info) in drm_display_info. This structure will be used to save and indicate if sink supports advanced HDMI 2.0 features - Adds another structure drm_scdc within drm_hdmi_info, to reflect scdc support and capabilities in connected HDMI 2.0 sink. - Checks the HF-VSDB block for presence of SCDC, and marks it in scdc structure - If SCDC is present, checks if sink is capable of generating SCDC read request, and marks it in scdc structure. V2: Addressed review comments Thierry: - Fix typos in commit message and make abbreviation consistent across the commit message. - Change structure object name from hdmi_info -> hdmi - Fix typos and abbreviations in description of structure drm_hdmi_info end the description with a full stop. - Create a structure drm_scdc, and keep all information related to SCDC register set (supported, read request supported) etc in it.

imx-drm PRE/PRG support, deferred plane disabling, separate alpha support - Initial support for the Prefetch Resolve Engine/Gasket on i.MX6QP, improving linear scanout buffer memory bandwidth utilization. This will in the future grow reordering support and allow direct scanout of Vivante tiled renderbuffers from the GPU. - Deferred plane disabling gets rid of some busy waiting in the atomic plane disable and crtc disable paths that lead to wait_for_vblank timeouts. - Add support for RGBA formats with a separate alpha plane, that can reduce memory bandwidth utilization for mostly transparent overlay planes by skipping color reads for completely transparent regions. - Allow moving an active overlay plane without enforcing a modeset. - Add 8-bit and 16-bit bayer formats to ipu_cpmem_set_image. - Set the base address in ipu_cpmem_set_image even for invalid formats to increase robustness against errors. - Use drm_plane_helper_check_state in plane atomic_check. - Some cleanup. * tag 'imx-drm-next-2017-03-17' of git://git.pengutronix.de/git/pza/linux: (22 commits) drm/imx: Remove unneeded definition for structure imx_drm_component drm/imx: use PRG/PRE when possible drm/imx: enable/disable PRG on CRTC enable/disable gpu: ipu-v3: only set non-zero AXI ID for IC when PRG is absent gpu: ipu-v3: hook up PRG unit gpu: ipu-v3: document valid IPUv3 compatibles and extend for i.MX6 QuadPlus gpu: ipu-v3: add driver for Prefetch Resolve Gasket gpu: ipu-v3: add DT binding for the Prefetch Resolve Gasket gpu: ipu-v3: add driver for Prefetch Resolve Engine gpu: ipu-v3: add DT binding for the Prefetch Resolve Engine drm/imx: ipuv3-plane: add support for separate alpha planes drm/imx: extend drm_plane_state_to_eba for separate channel support gpu: ipu-v3: add support for separate alpha channels drm: add RGB formats with separate alpha plane drm/imx: add deferred plane disabling drm/imx: don't wait for vblank and stop calling cleanup_planes in commit_tail gpu: ipu-v3: add unsynchronised DP channel disabling gpu: ipu-v3: remove IRQ dance on DC channel disable gpu: ipu-cpmem: add bayer formats to ipu_cpmem_set_image gpu: ipu-cpmem: set image base address even for incorrect formats ...

This BUG_ON() triggered for me once at shutdown, and I don't see a reason for the check. The code correctly checks whether the swap slot cache is usable or not, so an uninitialized swap slot cache is not actually problematic afaik. I've temporarily just switched the BUG_ON() to a WARN_ON_ONCE(), since I'm not sure why that seemingly pointless check was there. I suspect the real fix is to just remove it entirely, but for now we'll warn about it but not bring the machine down.

Pull parisc fixes from Helge Deller: - Mikulas Patocka added support for R_PARISC_SECREL32 relocations in modules with CONFIG_MODVERSIONS. - Dave Anglin optimized the cache flushing for vmap ranges. - Arvind Yadav provided a fix for a potential NULL pointer dereference in the parisc perf code (and some code cleanups). - I wired up the new statx system call, fixed some compiler warnings with the access_ok() macro and fixed shutdown code to really halt a system at shutdown instead of crashing & rebooting. * 'parisc-4.11-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: parisc: Fix system shutdown halt parisc: perf: Fix potential NULL pointer dereference parisc: Avoid compiler warnings with access_ok() parisc: Wire up statx system call parisc: Optimize flush_kernel_vmap_range and invalidate_kernel_vmap_range parisc: support R_PARISC_SECREL32 relocation in modules

Pull SCSI target fixes from Nicholas Bellinger: "The bulk of the changes are in qla2xxx target driver code to address various issues found during Cavium/QLogic's internal testing (stable CC's included), along with a few other stability and smaller miscellaneous improvements. There are also a couple of different patch sets from Mike Christie, which have been a result of his work to use target-core ALUA logic together with tcm-user backend driver. Finally, a patch to address some long standing issues with pass-through SCSI export of TYPE_TAPE + TYPE_MEDIUM_CHANGER devices, which will make folks using physical (or virtual) magnetic tape happy" * git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (28 commits) qla2xxx: Update driver version to 9.00.00.00-k qla2xxx: Fix delayed response to command for loop mode/direct connect. qla2xxx: Change scsi host lookup method. qla2xxx: Add DebugFS node to display Port Database qla2xxx: Use IOCB interface to submit non-critical MBX. qla2xxx: Add async new target notification qla2xxx: Export DIF stats via debugfs qla2xxx: Improve T10-DIF/PI handling in driver. qla2xxx: Allow relogin to proceed if remote login did not finish qla2xxx: Fix sess_lock & hardware_lock lock order problem. qla2xxx: Fix inadequate lock protection for ABTS. qla2xxx: Fix request queue corruption. qla2xxx: Fix memory leak for abts processing qla2xxx: Allow vref count to timeout on vport delete. tcmu: Convert cmd_time_out into backend device attribute tcmu: make cmd timeout configurable tcmu: add helper to check if dev was configured target: fix race during implicit transition work flushes target: allow userspace to set state to transitioning target: fix ALUA transition timeout handling ...
