[PATCH] drm/connector: Remove usage of the deprecated ida_simple_xxx API
by Bo Liu 17 Jun '22

17 Jun '22

Use ida_alloc_xxx()/ida_free() instead of ida_simple_get()/ida_simple_remove(). The latter is deprecated and more verbose.

[PATCH v3 0/6] drm/meson: add support for MIPI DSI Display
by Neil Armstrong 17 Jun '22

17 Jun '22

The Amlogic G12A, G12B & SM1 SoCs embeds a Synopsys DW-MIPI-DSI transceiver (ver 1.21a), with a custom glue managing the IP resets, clock and data input similar to the DW-HDMI glue on the same Amlogic SoCs. This adds support for the glue managing the transceiver, mimicing the init flow provided by Amlogic to setup the ENCL encoder, the glue, the transceiver, the digital D-PHY and the Analog PHY in the proper way. The DW-MIPI-DSI transceiver + D-PHY are clocked by the GP0 PLL, and the ENCL encoder + VIU pixel reader by the VCLK2 clock using the HDMI PLL. The DW-MIPI-DSI transceiver gets this pixel stream as input clocked with the VCLK2 clock. An optional "MEAS" clock can be enabled to measure the delay between each vsync feeding the DW-MIPI-DSI transceiver. This patchset is based on an earlier attempt at [1] for the AXG SoCs, but: - the AXG has a single clock source for both transceiver + pixel, which makes it an exception instead of a rule, it's simpler to add support for G12A then add AXG on it - previous glue code was a single monolitic code mixing encoders & bridges, this version is aligned on the previous cleanup done on HDMI & CVBS bridges architecture at [2] - since the only output of AXG is DSI, AXG VPU support is post-poned until we implement single-clock DSI support specific case on top of this. Changes from v2 at [4]: - Fixed patch 3 - Added reviews from Jagan - Rebased on v5.19-rc1 Changes from v1 at [3]: - fixed DSI host bindings - add reviewed-by tags for bindings - moved magic values to defines thanks to Martin's searches - added proper prefixes to defines - moved phy_configure to phy_init() dw-mipi-dsi callback - moved phy_on to a new phy_power_on() dw-mipi-dsi callback - correctly return phy_init/configure errors to callback returns [1] https://lore.kernel.org/r/20200907081825.1654-1-narmstrong@baylibre.com [2] https://lore.kernel.org/r/20211020123947.2585572-1-narmstrong@baylibre.com [3] https://lore.kernel.org/r/20200907081825.1654-1-narmstrong@baylibre.com [4] https://lore.kernel.org/r/20220120083357.1541262-1-narmstrong@baylibre.com Neil Armstrong (6): dt-bindings: display: add Amlogic MIPI DSI Host Controller bindings dt-bindings: display: meson-vpu: add third DPI output port drm/meson: venc: add ENCL encoder setup for MIPI-DSI output drm/meson: vclk: add DSI clock config drm/meson: add DSI encoder drm/meson: add support for MIPI-DSI transceiver .../display/amlogic,meson-dw-mipi-dsi.yaml | 116 ++++++ .../bindings/display/amlogic,meson-vpu.yaml | 5 + drivers/gpu/drm/meson/Kconfig | 7 + drivers/gpu/drm/meson/Makefile | 3 +- drivers/gpu/drm/meson/meson_drv.c | 7 + drivers/gpu/drm/meson/meson_dw_mipi_dsi.c | 358 ++++++++++++++++++ drivers/gpu/drm/meson/meson_dw_mipi_dsi.h | 160 ++++++++ drivers/gpu/drm/meson/meson_encoder_dsi.c | 160 ++++++++ drivers/gpu/drm/meson/meson_encoder_dsi.h | 12 + drivers/gpu/drm/meson/meson_registers.h | 25 ++ drivers/gpu/drm/meson/meson_vclk.c | 47 +++ drivers/gpu/drm/meson/meson_vclk.h | 1 + drivers/gpu/drm/meson/meson_venc.c | 211 ++++++++++- drivers/gpu/drm/meson/meson_venc.h | 6 + drivers/gpu/drm/meson/meson_vpp.h | 2 + 15 files changed, 1117 insertions(+), 3 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/amlogic,meson-dw-mipi-dsi.yaml create mode 100644 drivers/gpu/drm/meson/meson_dw_mipi_dsi.c create mode 100644 drivers/gpu/drm/meson/meson_dw_mipi_dsi.h create mode 100644 drivers/gpu/drm/meson/meson_encoder_dsi.c create mode 100644 drivers/gpu/drm/meson/meson_encoder_dsi.h -- 2.25.1

[PATCH 00/96] Refactor non_legacy_dai_naming flag
by Charles Keepax 17 Jun '22

17 Jun '22

Historically, the legacy DAI naming scheme was applied to platform drivers and the newer scheme to CODEC drivers. During componentisation the core lost the knowledge of if a driver was a CODEC or platform, they were all now components. To continue to support the legacy naming on older platform drivers a flag was added to the snd_soc_component_driver structure, non_legacy_dai_naming, to indicate to use the new scheme and this was applied to all CODECs as part of the migration. However, a slight issue appears to be developing with respect to this flag being opt in for the non-legacy scheme, which presumably we want to be the primary scheme used. Many codec drivers appear to forget to include this flag: grep -l -r "snd_soc_component_driver" sound/soc/codecs/*.c | xargs grep -L "non_legacy_dai_naming" | wc 48 48 556 Whilst in many cases the configuration of the DAIs themselves will cause the core to apply the new scheme anyway, it would seem more sensible to change the flag to legacy_dai_naming making the new scheme opt out. This patch series migrates across to such a scheme.

[PATCH v2] drm/nouveau/bios: Rename prom_init() and friends functions
by Christophe Leroy 17 Jun '22

17 Jun '22

While working at fixing powerpc headers, I ended up with the following error. drivers/gpu/drm/nouveau/nvkm/subdev/bios/shadowrom.c:48:1: error: conflicting types for 'prom_init'; have 'void *(struct nvkm_bios *, const char *)' make[5]: *** [scripts/Makefile.build:288: drivers/gpu/drm/nouveau/nvkm/subdev/bios/shadowrom.o] Error 1 powerpc and a few other architectures have a prom_init() global function.

[PATCH v6 0/5] Fix some races between sysfb device registration and drivers probe
by Javier Martinez Canillas 17 Jun '22

17 Jun '22

Hello, The patches in this series contain mostly changes suggested by Daniel Vetter Thomas Zimmermann. They aim to fix existing races between the Generic System Framebuffer (sysfb) infrastructure and the fbdev and DRM device registration. For example, it is currently possible for sysfb to register a platform device after a real DRM driver was registered and requested to remove the conflicting framebuffers. Or is possible for a simple{fb,drm} to match with a device previously registered by sysfb, even after a real driver is present. A symptom of this issue, was worked around with the commit fb561bf9abde ("fbdev: Prevent probing generic drivers if a FB is already registered") but that's really a hack and should be reverted instead. This series attempt to fix it more correctly and revert the mentioned hack. That will also allow to make the num_registered_fb variable not visible to drivers anymore, since that's internal to fbdev core. Pach 1 is just a simple cleanup in preparation for later patches. Patch 2 add a sysfb_disable() helper to allow disabling sysfb and unregister devices registered by sysfb. Patch 3 fixes the race that exists between sysfb devices registration and fbdev framebuffer devices registration, by disabling the sysfb when a DRM or fbdev driver requests to remove conflicting framebuffers. Patch 4 is the revert patch that was posted by Daniel before but dropped from his set and finally patch 5 is the one that makes num_registered_fb private to fbmem.c, to not allow drivers to use it anymore. The patches were tested on a rpi4 with the vc4, simpledrm and simplefb drivers, using different combinations of built-in and as a module. Best regards, Javier Changes in v6: - Drop sysfb_try_unregister() helper since is no longer needed. - Move the sysfb_disable() before the remove conflicting framebuffers loop (Daniel Vetter). - Drop patch "fbdev: Make sysfb to unregister its own registered devices" since was no longer needed. Changes in v5: - Move the sysfb_disable() call at conflicting framebuffers again to avoid the need of a DRIVER_FIRMWARE capability flag. - Add Daniel Vetter's Reviewed-by tag again since reverted to the old patch that he already reviewed in v2. - Drop patches that added a DRM_FIRMWARE capability and use them since the case those prevented could be ignored (Daniel Vetter). Changes in v4: - Make sysfb_disable() to also attempt to unregister a device. - Add patch to make registered_fb[] private. - Add patches that introduce the DRM_FIRMWARE capability and usage. Changes in v3: - Add Thomas Zimmermann's Reviewed-by tag to patch #1. - Call sysfb_disable() when a DRM dev and a fbdev are registered rather than when conflicting framebuffers are removed (Thomas Zimmermann). - Call sysfb_disable() when a fbdev framebuffer is registered rather than when conflicting framebuffers are removed (Thomas Zimmermann). - Drop Daniel Vetter's Reviewed-by tag since patch changed a lot. - Rebase on top of latest drm-misc-next branch. Changes in v2: - Rebase on top of latest drm-misc-next and fix conflicts (Daniel Vetter). - Add kernel-doc comments and include in other_interfaces.rst (Daniel Vetter). - Explain in the commit message that fbmem has to unregister the device as fallback if a driver registered the device itself (Daniel Vetter). - Also explain that fallback in a comment in the code (Daniel Vetter). - Don't encode in fbmem the assumption that sysfb will always register platform devices (Daniel Vetter). - Add a FIXME comment about drivers registering devices (Daniel Vetter). - Drop RFC prefix since patches were already reviewed by Daniel Vetter. - Add Daniel Reviewed-by tags to the patches.

[PATCH v2] dma-buf: Move sysfs work out of DMA-BUF export path
by T.J. Mercier 17 Jun '22

17 Jun '22

Recently, we noticed an issue where a process went into direct reclaim while holding the kernfs rw semaphore for sysfs in write (exclusive) mode. This caused processes who were doing DMA-BUF exports and releases to go into uninterruptible sleep since they needed to acquire the same semaphore for the DMA-BUF sysfs entry creation/deletion. In order to avoid blocking DMA-BUF export for an indeterminate amount of time while another process is holding the sysfs rw semaphore in exclusive mode, this patch moves the per-buffer sysfs file creation to the default work queue. Note that this can lead to a short-term inaccuracy in the dmabuf sysfs statistics, but this is a tradeoff to prevent the hot path from being blocked. A work_struct is added to dma_buf to achieve this, but as it is unioned with the kobject in the sysfs_entry, dma_buf does not increase in size.

[PATCH] drm/mediatek: fix crtc index computation

The code always assume that the main path is enabled, which is not always the case. When the main path is not enabled, the CRTC index of the ext path is incorrect which makes the secondary path not usable. Fix the CRTC index calculation.
