2023-05-05drm/rockchip: vop: Leave vblank enabled in self-refreshBrian Norris1-4/+4
If we disable vblank when entering self-refresh, vblank APIs (like DRM_IOCTL_WAIT_VBLANK) no longer work. But user space is not aware when we enter self-refresh, so this appears to be an API violation -- that DRM_IOCTL_WAIT_VBLANK fails with EINVAL whenever the display is idle and enters self-refresh. The downstream driver used by many of these systems never used to disable vblank for PSR, and in fact, even upstream, we didn't do that until radically redesigning the state machine in commit 6c836d965bad ("drm/rockchip: Use the helpers for PSR"). Thus, it seems like a reasonable API fix to simply restore that behavior, and leave vblank enabled. Note that this appears to potentially unbalance the drm_crtc_vblank_{off,on}() calls in some cases, but: (a) drm_crtc_vblank_on() documents this as OK and (b) if I do the naive balancing, I find state machine issues such that we're not in sync properly; so it's easier to take advantage of (a). This issue was exposed by IGT's kms_vblank tests, and reported by KernelCI. The bug has been around a while (longer than KernelCI noticed), but was only exposed once self-refresh was bugfixed more recently, and so KernelCI could properly test it. Some other notes in: https://lore.kernel.org/dri-devel/Y6OCg9BPnJvimQLT@google.com/ Re: renesas/master bisection: igt-kms-rockchip.kms_vblank.pipe-A-wait-forked on rk3399-gru-kevin == Backporting notes: == Marking as 'Fixes' commit 6c836d965bad ("drm/rockchip: Use the helpers for PSR"), but it probably depends on commit bed030a49f3e ("drm/rockchip: Don't fully disable vop on self refresh") as well. We also need the previous patch ("drm/atomic: Allow vblank-enabled + self-refresh "disable""), of course. v3: * no update v2: * skip unnecessary lock/unlock Fixes: 6c836d965bad ("drm/rockchip: Use the helpers for PSR") Cc: <stable@vger.kernel.org> Reported-by: "kernelci.org bot" <bot@kernelci.org> Link: https://lore.kernel.org/dri-devel/Y5itf0+yNIQa6fU4@sirena.org.uk/ Signed-off-by: Brian Norris <briannorris@chromium.org> Signed-off-by: Sean Paul <seanpaul@chromium.org> Link: https://patchwork.freedesktop.org/patch/msgid/20230109171809.v3.2.Ic07cba4ab9a7bd3618a9e4258b8f92ea7d10ae5a@changeid

2023-03-09drm/rockchip: dw_hdmi: relax mode_valid hookSascha Hauer1-7/+19
The driver checks if the pixel clock of the given mode matches an entry in the mpll config table. At least for the Synopsys phy the frequencies in the mpll table are meant as a frequency range up to which the entry works, not as a frequency that must match the pixel clock. Return MODE_OK when the pixelclock is smaller than one of the mpll frequencies to allow for more display resolutions. Limit this behaviour to the Synopsys phy at the moment and keep the current behaviour of forcing exact pixelclock rates for the other phys until it has been sorted out how and if the vendor specific phys work with non standard clock rates.

2023-03-09drm/rockchip: vop: limit maximum resolution to hardware capabilitiesSascha Hauer4-5/+36
The different VOP variants support different maximum resolutions. Reject resolutions that are not supported by a specific variant. This hasn't been a problem in the upstream driver so far as 1920x1080 has been the maximum resolution supported by the HDMI driver and that resolution is supported by all VOP variants. Now with higher resolutions supported in the HDMI driver we have to limit the resolutions to the ones supported by the VOP. The actual maximum resolutions are taken from the Rockchip downstream Kernel.

The variable possible_crtcs is only initialized for primary and overlay planes. Since the VOP2 driver only supports these plane types at the moment, the current code is safe. However, in order to provide a future-proof solution, fix the initialization of the variable.

2022-11-12drm/rockchip: Use drm_mode_copy()Ville Syrjälä3-3/+3
struct drm_display_mode embeds a list head, so overwriting the full struct with another one will corrupt the list (if the destination mode is on a list). Use drm_mode_copy() instead which explicitly preserves the list head of the destination mode. Even if we know the destination mode is not on any list using drm_mode_copy() seems decent as it sets a good example. Bad examples of not using it might eventually get copied into code where preserving the list head actually matters. Obviously one case not covered here is when the mode itself is embedded in a larger structure and the whole structure is copied. But if we are careful when copying into modes embedded in structures I think we can be a little more reassured that bogus list heads haven't been propagated in. @is_mode_copy@ @@ drm_mode_copy(...) { ... } @depends on !is_mode_copy@ struct drm_display_mode *mode; expression E, S; @@ ( - *mode = E + drm_mode_copy(mode, &E) | - memcpy(mode, E, S) + drm_mode_copy(mode, E) ) @depends on !is_mode_copy@ struct drm_display_mode mode; expression E; @@ ( - mode = E + drm_mode_copy(&mode, &E) | - memcpy(&mode, E, S) + drm_mode_copy(&mode, E) ) @@ struct drm_display_mode *mode; @@ - &*mode + mode Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Sandy Huang <hjc@rock-chips.com> Cc: "Heiko Stübner" <heiko@sntech.de> Cc: linux-arm-kernel@lists.infradead.org Cc: linux-rockchip@lists.infradead.org Link: https://patchwork.freedesktop.org/patch/msgid/20221107192545.9896-7-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2022-10-29drm/rockchip: vop2: disable planes when disabling the crtcMichael Tretter1-0/+4
The vop2 driver needs to explicitly disable the planes if the crtc is disabled. Unless the planes are explicitly disabled, the address of the last framebuffer is kept in the registers of the VOP2. When re-enabling the encoder after it has been disabled by the driver, the VOP2 will start and read the framebuffer that has been freed but is still pointed to by the register. The iommu will catch these read accesses and print errors. Explicitly disable the planes when the crtc is disabled to reset the registers.

2022-10-29drm/rockchip: fix fbdev on non-IOMMU devicesJohn Keeping1-1/+4
When switching to the generic fbdev infrastructure, it was missed that framebuffers were created with the alloc_kmap parameter to rockchip_gem_create_object() set to true. The generic infrastructure calls this via the .dumb_create() driver operation and thus creates a buffer without an associated kmap. alloc_kmap only makes a difference on devices without an IOMMU, but when it is missing rockchip_gem_prime_vmap() fails and the framebuffer cannot be used. Detect the case where a buffer is being allocated for the framebuffer and ensure a kernel mapping is created in this case.
