2020-04-03drm/hisilicon: Enforce 128-byte stride alignment to fix the hardware limitationTian Tao3-7/+8
because the hardware limitation,The initial color depth must set to 32bpp and must set the FB Offset of the display hardware to 128Byte alignment, which is used to solve the display problem at 800x600 and 1440x900 resolution under 16bpp. Signed-off-by: Tian Tao <tiantao6@hisilicon.com> Signed-off-by: Gong junjie <gongjunjie2@huawei.com> Acked-by: Xinliang Liu <xinliang.liu@linaro.org> Signed-off-by: Xinliang Liu <xinliang.liu@linaro.org> Link: https://patchwork.freedesktop.org/patch/msgid/1583466184-7060-4-git-send-email-tiantao6@hisilicon.com

2020-03-31drm/qxl: Use correct notify port address when creating cursor ringHuacai Chen1-1/+1
The command ring and cursor ring use different notify port addresses definition: QXL_IO_NOTIFY_CMD and QXL_IO_NOTIFY_CURSOR. However, in qxl_device_init() we use QXL_IO_NOTIFY_CMD to create both command ring and cursor ring. This doesn't cause any problems now, because QEMU's behaviors on QXL_IO_NOTIFY_CMD and QXL_IO_NOTIFY_CURSOR are the same. However, QEMU's behavior may be change in future, so let's fix it. P.S.: In the X.org QXL driver, the notify port address of cursor ring is correct.

2020-03-30drm: rework SET_MASTER and DROP_MASTER perm handlingEmil Velikov2-2/+69
This commit reworks the permission handling of the two ioctls. In particular it enforced the CAP_SYS_ADMIN check only, if: - we're issuing the ioctl from process other than the one which opened the node, and - we are, or were master in the past This ensures that we: - do not regress the systemd-logind style of DRM_MASTER arbitrator - allow applications which do not use systemd-logind to drop their master capabilities (and regain them at later point) ... w/o running as root. See the comment above drm_master_check_perm() for more details. v1: - Tweak wording, fixup all checks, add igt test v2: - Add a few more comments, grammar nitpicks.

Most platforms with a Mali-400 or Mali-450 GPU also have support for changing the GPU clock frequency. Add devfreq support so the GPU clock rate is updated based on the actual GPU usage when the "operating-points-v2" property is present in the board.dts. The actual devfreq code is taken from panfrost_devfreq.c and modified so it matches what the lima hardware needs: - a call to dev_pm_opp_set_clkname() during initialization because there are two clocks on Mali-4x0 IPs. "core" is the one that actually clocks the GPU so we need to control it using devfreq. - locking when reading or writing the devfreq statistics because (unlike than panfrost) we have multiple PP and GP IRQs which may finish jobs concurrently.

2020-03-27drm/dp_mst: Remove single tx msg restriction.Sean Paul1-12/+2
Now that we can support multiple simultaneous replies, remove the restrictions placed on sending new tx msgs. This patch essentially just reverts commit 5a64967a2f3b ("drm/dp_mst: Have DP_Tx send one msg at a time") now that the problem is solved in a different way.

2020-03-27drm/mst: Support simultaneous down repliesSean Paul1-32/+48
Currently we have one down reply message servicing the mst manager, so we need to serialize all tx msgs to ensure we only have one message in flight at a time. For obvious reasons this is suboptimal (but less suboptimal than the free-for-all we had before serialization). This patch removes the single down_rep_recv message from manager and adds 2 replies in the branch structure. The 2 replies mirrors the tx_slots which we use to rate-limit outgoing messages and correspond to seqno in the packet headers.

2020-03-27drm/mst: Separate sideband packet header parsing from message buildingSean Paul1-45/+57
In preparation of per-branch device down message handling, separate header parsing from message building. This will allow us to peek at figure out which branch device the message is from before starting to parse the message contents.

2020-03-27drm/fb-helper: Add TODO for making drm_fb_helper_alloc_fbi fill aperturesHans de Goede1-0/+8
Currently drivers using drm_fbdev_generic_setup() end up with a single empty aperture in their fb_info struct. Not having the proper info in the apertures list causes register_framebuffer to not remove conflicting framebuffers, which some drivers currently workaround by manually calling drm_fb_helper_remove_conflicting_pci_framebuffers(). Add a TODO as a reminder that we need to fix this.
