[v7 0/5] drm: Support basic DPCD backlight in panel-simple and add a new panel ATNA33XC20
by Rajeev Nandan 23 Jun '21

23 Jun '21

This series adds the support for the eDP panel that needs the backlight controlling over the DP AUX channel using DPCD registers of the panel as per the VESA's standard. This series also adds support for the Samsung eDP AMOLED panel that needs DP AUX to control the backlight, and introduces new delays in the @panel_desc.delay to support this panel. This patch series depends on the following two series: - Doug's series [1], exposed the DP AUX channel to the panel-simple. - Lyude's series [2], introduced new drm helper functions for DPCD backlight. This series is the logical successor to the series [3]. Changes in v1: - Created dpcd backlight helper with very basic functionality, added backlight registration in the ti-sn65dsi86 bridge driver. Changes in v2: - Created a new DisplayPort aux backlight driver and moved the code from drm_dp_aux_backlight.c (v1) to the new driver. Changes in v3: - Fixed module compilation (kernel test bot). Changes in v4: - Added basic DPCD backlight support in panel-simple. - Added support for a new Samsung panel ATNA33XC20 that needs DPCD backlight controlling and has a requirement of delays between enable GPIO and regulator. Changes in v5: Addressed review suggestions from Douglas: - Created a new API drm_panel_dp_aux_backlight() in drm_panel.c - Moved DP AUX backlight functions from panel-simple.c to drm_panel.c - panel-simple probe() calls drm_panel_dp_aux_backlight() to create backlight when the backlight phandle is not specified in panel DT and DP AUX channel is present. - Added check for drm_edp_backlight_supported() before registering. - Removed the @uses_dpcd_backlight flag from panel_desc as this should be auto-detected. - Updated comments/descriptions. Changes in v6: - Rebased - Updated wanrning messages, fixed word wrapping in comments. - Fixed ordering of memory allocation Changes in v7: - Updated the disable_to_power_off and power_to_enable panel delays as discovered at <https://crrev.com/c/2966167> (Douglas) [1] https://lore.kernel.org/dri-devel/20210525000159.3384921-1-dianders@chromiu… [2] https://lore.kernel.org/dri-devel/20210514181504.565252-1-lyude@redhat.com/ [3] https://lore.kernel.org/dri-devel/1619416756-3533-1-git-send-email-rajeevny… Rajeev Nandan (5): drm/panel: add basic DP AUX backlight support drm/panel-simple: Support DP AUX backlight drm/panel-simple: Support for delays between GPIO & regulator dt-bindings: display: simple: Add Samsung ATNA33XC20 drm/panel-simple: Add Samsung ATNA33XC20 .../bindings/display/panel/panel-simple.yaml | 2 + drivers/gpu/drm/drm_panel.c | 108 +++++++++++++++++++++ drivers/gpu/drm/panel/panel-simple.c | 67 +++++++++++++ include/drm/drm_panel.h | 15 ++- 4 files changed, 188 insertions(+), 4 deletions(-) -- 2.7.4

[PATCH 2/3] drm: rcar-du: Only initialise TVM_TVSYNC mode when supported
by Kieran Bingham 23 Jun '21

23 Jun '21

From: Kieran Bingham <kieran.bingham+renesas(a)ideasonboard.com> The R-Car DU as found on the D3, E3, and V3U do not have support for an external synchronisation method. In these cases, the dsysr cached register should not be initialised in DSYSR_TVM_TVSYNC, but instead should be left clear to configure as DSYSR_TVM_MASTER by default.

I did some testing and it looks good, thanks I see Alex has this in hch-mdev-direct-v4 in linux-next now, so expecting this to be in the next merge window? The AP prep patches seemed sorted so I'll resend the AP patch in three weeks Jason

[PATCH v7 00/15] TegraDRM UAPI
by Mikko Perttunen 22 Jun '21

22 Jun '21

Hi all, here's the seventh revision of the TegraDRM UAPI proposal. Only some small changes to v6 here to fix things on older Tegras with certain configuration combinations, as well as rebasing to latest linux-next. The following pieces of userspace have been updated to support this revision of the UAPI (unchanged from v6): * vaapi-tegra-driver - https://github.com/cyndis/vaapi-tegra-driver Experimental support for MPEG2 and H264 decoding on T210, T186 and T194. * xf86-video-opentegra - https://github.com/grate-driver/xf86-video-opentegra X11 userspace acceleration driver for Tegra20, Tegra30, and Tegra114. * grate - https://github.com/grate-driver/grate 3D rendering testbed for Tegra20, Tegra30, and Tegra114 The series can be also found in https://github.com/cyndis/linux/commits/work/tegradrm-v7.

[PATCH 1/1] drm/kmb: Fix error return code in kmb_hw_init()

When call platform_get_irq() to obtain the IRQ of the lcd fails, the returned error code should be propagated. However, we currently do not explicitly assign this error code to 'ret'.

[PATH 0/4] [RFC] Support virtual DRM
by Tomohito Esaki 22 Jun '21

22 Jun '21

Hello Sorry, there was a typo in the dri-devel mail address, so I've resend it. --- Virtual DRM splits the overlay planes of a display controller into multiple virtual devices to allow each plane to be accessed by each process. This makes it possible to overlay images output from multiple processes on a display. For example, one process displays the camera image without compositor while another process overlays the UI. Virtual DRM driver doesn’t directly control the display hardware and has no access to the physical bus. Instead, the virtual DRM driver issues requests to the standard DRM device driver (parent) when the hardware needs to be controlled. The parent is modified to notify the virtual DRM driver of interruptevents from the display hardware. Therefore, in order to use virtual DRM, each DRM device driver needs to add code to support virutal DRM. The only driver supported in this patch series is rcar-du. This patch series is divided into multiple. The first patch adds vDRM feature to DRM, and the second patch support vDRM for the rcar-du driver. The other patches add documentation. In particular, I would appreciate your advice on the following points: * virtual DRM generalization I've only tested with rcar-du, is there anything I should consider to make virtual DRM work with other drivers? * Integration to upstream I think it is a good idea to add virtual DRM to the DRM core functionality, but I would appreciate any suggestions on what needs to be improved for integration to upstream. * dumb_create and fb_create callback I think that the dumb_create and fb_create callbacks need to be done by the parent, and it is preferable to use the parent's callbacks as they are. However, since the dumb buffer needs to be registered in the parent and the fb handle needs to be registered in the drm_file of the vDRM, the dumb_create callbacks from the parent driver cannot be used as is. Therefore, the current implementation of the dumb_create callback is workarround. What do you think is the best way to deal with this issue?

[PATCH 00/11] dma_fence critical sections annotations for atomic
by Daniel Vetter 22 Jun '21

22 Jun '21

Hi all, Finally gotten around to refreshing all the various fence anntotions I've hast last summer. Or well parts of it: - entire amdgpu and drm/scheduler annotations postponed for now, because there's way too many splats in there that need some work - in recent patches I've seen quite a few dma_resv_lock or kmalloc in atomic_commit_tail, which doesn't work in full generality with the rules for dma_fences we've discussed and encoded in lockdep. These annotations should catch stuff like this. Review comments and testing very much welcome.

[PATCH] drm/auth: Move master pointer from drm_device to drm_file
by Qiang Ma 22 Jun '21

22 Jun '21

The drm_file pointer clears to zero during multi-user switching, so it needs to call drm_new_set_master for master pointer from drm_file.
