[PATCH 0/2] Add the property to make ocp level selectable
by cy_huang 06 Jun '22

06 Jun '22

From: ChiYuan Huang <cy_huang(a)richtek.com> This patch series is to make ocp level selectable. Some application design use small inductor. And it's easy to trigger the over current protection. Due to the OCP limit, It make the brightness current not match the configured value. To meet the HW design, the ocp level have to be selectable. ChiYuan Huang (2): dt-bindings: backlight: rt4831: Add the new property for ocp level selection backlight: rt4831: Add the property parsing for ocp level selection .../bindings/leds/backlight/richtek,rt4831-backlight.yaml | 8 ++++++++ drivers/video/backlight/rt4831-backlight.c | 13 +++++++++++++ include/dt-bindings/leds/rt4831-backlight.h | 5 +++++ 3 files changed, 26 insertions(+) -- 2.7.4

[PATCH] dt-bindings: Fix properties without any type
by Rob Herring 06 Jun '22

06 Jun '22

Now that the schema tools can extract type information for all properties (in order to decode dtb files), finding properties missing any type definition is fairly trivial though not yet automated. Fix the various property schemas which are missing a type. Most of these tend to be device specific properties which don't have a vendor prefix. A vendor prefix is how we normally ensure a type is defined.

How should "max bpc" KMS property work?
by Pekka Paalanen 03 Jun '22

03 Jun '22

Hi all, I'm working on setting HDR & WCG video modes in Weston, and I thought setting "max bpc" KMS property on the connector would be a good idea. I'm confused about how it works though. I did some digging in https://gitlab.freedesktop.org/wayland/weston/-/issues/612 Summary: - Apparently the property was originally added as a manual workaround for sink hardware behaving badly with high depth. A simple end user setting for "max bpc" would suffice for this use. - Drivers will sometimes automatically choose a lower bpc than the "max bpc" value, but never bigger. - amdgpu seems to (did?) default "max bpc" to 8, meaning that I definitely want to raise it. If I always slam "max bpc" to the highest supported value for that property, do I lose more than workarounds for bad sink hardware? Do I lose the ability to set video modes that take too much bandwidth at uncapped driver-selected bpc while capping the bpc lower would allow me to use those video modes? Or, are drivers required to choose a lower-than-usual but highest usable bpc to make the requested video mode squeeze through the connector and link? Do I need to implement a fallback strategy in a display server, starting from the highest possible "max bpc" value, and if my modeset is rejected, repeatedly try with lower "max bpc" setting until it works or I'm out of bpc options? Thanks, pq

[Bug 205089] New: amdgpu : drm:amdgpu_cs_ioctl : Failed to initialize parser -125
by bugzilla-daemon＠bugzilla.kernel.org 02 Jun '22

https://bugzilla.kernel.org/show_bug.cgi?id=205089 Bug ID: 205089 Summary: amdgpu : drm:amdgpu_cs_ioctl : Failed to initialize parser -125 Product: Drivers Version: 2.5 Kernel Version: 5.3.2 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri(a)kernel-bugs.osdl.org Reporter: maxijac(a)free.fr Regression: No Hello, I am experiencing freezes with kernel 5.3.2 and amdgpu on a Vega 64 card. This happens during games (I experience it on CS:GO) but it is a bit random and takes time to eventually trigger. Once it triggers my dmesg is filled with errors: [ 9156.537524] [drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to initialize parser -125! [ 9156.747176] [drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to initialize parser -125! [ 9156.747224] [drm:amdgpu_cs_ioctl [amdgpu]] *ERROR* Failed to initialize parser -125!

When it happens, the image hangs and PC is unresponsive. Sometimes I manage to switch to a TTY, but then the screen is corrupted. HW: - AMD Ryzen 2700X CPU - AMD RX vega 64 SW: - Kernel 5.3.2 - Mesa 19.2.0 -- You are receiving this mail because: You are watching the assignee of the bug.
