Do not unconditionally invoke function 0x1B without checking for its availability, it leads to an infinite loop on some firmware. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=104791 Fixes: 5addcf0a ("nouveau: add runtime PM support (v0.9)") Reviewed-by:

Return the set of supported functions to the caller. No functional changes. Reviewed-by:

Peter Wu authored
Ensure that the returned set of supported DSM functions (MUX, Optimus) match the ACPI handle that is set in nouveau_dsm_pci_probe. As there are no machines with a MUX function on just one PCI device and an Optimus on another, there should not be a functional impact. This change however makes this implicit assumption more obvious. Convert int to bool and rename has_dsm to has_mux while at it. Let the caller set nouveau_dsm_priv.dhandle as needed. v2: pass dhandle to the caller. Reviewed-by:

The patch f045f459 ("drm/nouveau/fbcon: fix out-of-bounds memory accesses") tries to fix some out of memory accesses. Unfortunatelly, the patch breaks the display when using fonts with width that is not divisiable by 8. The monochrome bitmap for each character is stored in memory by lines from top to bottom. Each line is padded to a full byte. For example, for 22x11 font, each line is padded to 16 bits, so each character is consuming 44 bytes total, that is 11 32-bit words. The patch f045f459 changed the logic to "dsize = ALIGN(image->width * image->height, 32) >> 5", that is just 8 words - this is incorrect and it causes display corruption. This patch adds the necesary padding of lines to 8 bytes. This patch should be backported to stable kernels where f045f459 was backported. Signed-off-by:

This is an update to the previous drm bridge pull request. The ADV7511 driver's conversion from slave encoder to bridge meant that its users (the rcar-du kms driver) should use the bridge interface too. This pull request now also contains a commit that updates the rcar-du's hdmi encoder interface from slave encoder to bridge. The other updates are as before: - Converts the ADV7511 i2c slave encoder driver to a bridge driver. Adds support for the ADV7533 bridge chip. - Add bridge driver for TC358767 (DSI/DPI to eDP) encoder chips. * 'drm_bridge_for_4.8' of https://github.com/boddob/linux: drm: rcar-du: Remove i2c slave encoder interface for hdmi encoder drm/bridge: tc358767: Add DPI to eDP bridge driver dt-bindings: tc358767: add DT documentation dt-bindings: drm/bridge: Update bindings for ADV7533 drm/bridge: adv7533: Change number of DSI lanes dynamically drm/bridge: adv7533: Use internal timing generator drm/bridge: adv7533: Create a MIPI DSI device drm/bridge: adv7533: Initial support for ADV7533 drm/bridge: adv7511: Fix mutex deadlock when interrupts are disabled drm/i2c: adv7511: Move to bridge folder drm/i2c: adv7511: Convert to drm_bridge

This time, a bunch of cleanups and refactoring work so that we can get dt bindings upstream. In general, we keep compatibility with existing downstream bindings as much as possible, to make backports to device kernels easier, but now we have cleaner upstream bindings so that we can start landing gpu/display support in upstream dts files. Plus shrinker and madvise support, which has been on my todo list for a long time. And support for arbitrary # of cmd bufs in submit ioctl (I've got libdrm+mesa userspace for this on branches) to enable some of the mesa batch/reorder stuff I'm working on. Userspace decides whether this is supported based on advertised driver version. For the interesting userspace bits, see: https://github.com/freedreno/libdrm/commit/1baf03ac6e77049d9c8be1e3d5164283ce82c9db Plus support for ASoC hdmi audio codec, and few other random other cleanups. * 'msm-next' of git://people.freedesktop.org/~robclark/linux: (52 commits) drm/msm: Delete an unnecessary check before drm_gem_object_unreference() drm/msm: Delete unnecessary checks before drm_gem_object_unreference_unlocked() drm/msm/hdmi: Delete an unnecessary check before the function call "kfree" drm/msm: return -EFAULT instead of bytes remaining drm/msm/hdmi: use PTR_ERR_OR_ZERO() to simplify the code drm/msm: add missing of_node_put after calling of_parse_phandle drm/msm: Replace drm_fb_get_bpp_depth() with drm_format_plane_cpp() drm/msm/dsi: Fix return value check in msm_dsi_host_set_display_mode() drm: msm: Add ASoC generic hdmi audio codec support. drm/msm/rd: add module param to dump all bo's drm/msm/rd: split out snapshot_buf helper drm/msm: bump kernel api version drm/msm: deal with arbitrary # of cmd buffers drm/msm: wire up vmap shrinker drm/msm: change gem->vmap() to get/put drm/msm: shrinker support drm/msm: add put_iova() helper drm/msm: add madvise ioctl drm/msm: use mutex_lock_interruptible for submit ioctl dt-bindings: msm/mdp: Provide details on MDP interface ports ...

The hdmi output in rcar-du uses the i2c slave encoder interface to link to the adv7511 encoder chip. The kms driver creates encoder and connector entities that internally uses the drm_encoder_slave_funcs ops provided by the slave encoder driver. Change the driver such that it expects a bridge entity instead of a slave encoder. The hdmi connector code isn't needed anymore as we expect the adv7511 bridge driver to create/manage the connector. Note that the kms driver still expects a connector node for hdmi to be present in DT. This node has no connection to the connector created by the bridge driver. Tested-by:
