2018-07-05drm: mali-dp: Add debugfs file for reporting internal errorsAlexandru Gheorghe
Status register contains a lot of bits for reporting internal errors inside Mali DP. Currently, we just silently ignore all of the errors, that doesn't help when we are investigating different bugs, especially on the FPGA models which have a lot of constraints, so we could easily end up in AXI or underrun errors. Add a new file called debug that contains an aggregate of the errors reported by the Mali DP hardware. E.g: [root@alarm ~]# cat /sys/kernel/debug/dri/1/debug [DE] num_errors : 167 [DE] last_error_status : 0x00000001 [DE] last_error_vblank : 385 [SE] num_errors : 3 [SE] last_error_status : 0x00e23001 [SE] last_error_vblank : 201 Changes since v2: - Add lock to protect the errors stats. - Add possibility to reset the error stats by writing anything to the debug file.

2018-07-05drm/mali-dp: Improve writeback handling for DP500.Liviu Dudau
Mali DP500 operates in continuous writeback mode (writes frame content until stopped) and it needs special handling in order to behave like a one-shot writeback engine. The original state machine added for DP500 was a bit fragile, as it did not handle correctly cases where a new atomic commit was in progress when the SE IRQ happens and it would commit some partial updates. Improve the handling by adding a parameter to the set_config_valid() function to clear the config valid bit in hardware before starting a new commit and by introducing a MW_RESTART state in the writeback state machine to cater for the case where a new writeback commit gets submitted while the last one is still being active.

2018-07-05drm: mali-dp: Add writeback connectorBrian Starkey
Mali-DP has a memory writeback engine which can be used to write the composition result to a memory buffer. Expose this functionality as a DRM writeback connector on supported hardware. Changes since v1: Daniel Vetter: - Don't require a modeset when writeback routing changes - Make writeback connector always disconnected Changes since v2: - Rebase onto new drm_writeback_connector - Add reset callback, allocating subclassed state Daniel Vetter: - Squash out-fence support into this commit Gustavo Padovan: - Don't signal fence directly from driver (and drop malidp_mw_job) Changes since v3: - Modifications to fit with Mali-DP commit tail changes Signed-off-by: Brian Starkey <brian.starkey@arm.com> [rebased and fixed conflicts] Signed-off-by: Mihail Atanassov <mihail.atanassov@arm.com> Signed-off-by: Liviu Dudau <liviu.dudau@arm.com>

2018-07-05drm/mali-dp: Add writeback support for DP500.Liviu Dudau
Mali DP500 behaves differently from the rest of the Mali DP IP, in that it does not have a one-shot mode and keeps writing the content of the current frame to the provided memory area until stopped. As a way of emulating the one-shot behaviour, we are going to use the CVAL interrupt that is being raised at the start of each frame, during prefetch phase, to act as End-of-Write signal, but with a twist: we are going to disable the memory write engine right after we're notified that it has been enabled, using the knowledge that the bit controlling the enabling will only be acted upon on the next vblank/prefetch. CVAL interrupt will fire durint the next prefetch phase every time the global CVAL bit gets set, so we need a state byte to track the memory write enabling. We also need to pay attention during the disabling of the memory write engine as that requires the CVAL bit to be set in the control register, but we don't want to do that during an atomic commit, as it will write into the hardware a partial state.

The transitional helpers are supposed to be directly plugged in as implementations of these methods, but doing so generates a warning. Add the missing argument.

2018-07-01drm/pl111: Support Nomadik LCDC variantLinus Walleij
The Nomadik has a variant of the PL110 known as "Color LCD Controller" LCDC. This variant has the same bit ordering as the DRM subsystem (in difference from the other variants) and adds a few bits for the control of 5551, 565 etc in the control register. Notably it also adds a packed RGB888 24BPP mode. We add support by detecting this variant and also adding a small plug-in that will mux the LCDC out if the ASIC happens to be muxed to the other graphics controller (they are mutually exclusive).

Pull block fixes from Jens Axboe: "Small set of fixes for this series. Mostly just minor fixes, the only oddball in here is the sg change. The sg change came out of the stall fix for NVMe, where we added a mempool and limited us to a single page allocation. CONFIG_SG_DEBUG sort-of ruins that, since we'd need to account for that. That's actually a generic problem, since lots of drivers need to allocate SG lists. So this just removes support for CONFIG_SG_DEBUG, which I added back in 2007 and to my knowledge it was never useful. Anyway, outside of that, this pull contains: - clone of request with special payload fix (Bart) - drbd discard handling fix (Bart) - SATA blk-mq stall fix (me) - chunk size fix (Keith) - double free nvme rdma fix (Sagi)" * tag 'for-linus-20180629' of git://git.kernel.dk/linux-block: sg: remove ->sg_magic member drbd: Fix drbd_request_prepare() discard handling blk-mq: don't queue more if we get a busy return block: Fix cloning of requests with a special payload nvme-rdma: fix possible double free of controller async event buffer block: Fix transfer when chunk sectors exceeds max
2018-06-29drm/vc4: Make DSI call into the bridge after the DSI link is enabled.Eric Anholt
This allows panels or bridges that need to send DSI commands during pre_enable() to successfully send them. We delay DISP0 (aka the actual display) enabling until after pre_enable so that pixels aren't streaming before then. v2: Just clear out the encoder->bridge value to disable the midlayer calls (idea by Andrzej Hajda).
