[PATCH] drm/rockchip: Require the YTR modifier for AFBC

by Alyssa Rosenzweig

The AFBC decoder used in the Rockchip VOP assumes the use of the YUV-like colourspace transform (YTR). YTR is lossless for RGB(A) buffers, which covers the RGBA8 and RGB565 formats supported in vop_convert_afbc_format. Use of YTR is signaled with the AFBC_FORMAT_MOD_YTR modifier, which prior to this commit was missing. As such, a producer would have to generate buffers that do not use YTR, which the VOP would erroneously decode as YTR, leading to severe visual corruption. The upstream AFBC support was developed against a captured frame, which failed to exercise modifier support. Prior to bring-up of AFBC in Mesa (in the Panfrost driver), no open userspace respected modifier reporting. As such, this change is not expected to affect broken userspaces. Tested on RK3399 with Panfrost and Weston.

[PATCH] iio: adc: ab8500-gpadc: Fix off by 10 to 3

by Linus Walleij

Fix an off by three orders of magnitude error in the AB8500 GPADC driver. Luckily it showed up quite quickly when trying to make use of it. The processed reads were returning microvolts, microamperes and microcelsius instead of millivolts, milliamperes and millicelsius as advertised.

[PATCH v2] x86/apic/of: Fix CPU devicetree-node lookups

by Johan Hovold

Architectures that describe the CPU topology in devicetree and that do not have an identity mapping between physical and logical CPU ids need to override the default implementation of arch_match_cpu_phys_id(). Failing to do so breaks CPU devicetree-node lookups using of_get_cpu_node() and of_cpu_device_node_get() which several drivers rely on. It also causes the CPU struct devices exported through sysfs to point to the wrong devicetree nodes. On x86, CPUs are described in devicetree using their APIC ids and those do not generally coincide with the logical ids, even if CPU0 typically uses APIC id 0. Add the missing implementation of arch_match_cpu_phys_id() so that CPU-node lookups work also with SMP. Apart from fixing the broken sysfs devicetree-node links this likely do not affect users of mainline kernels as the above mentioned drivers are currently not used on x86 as far as I know. Fixes: 4e07db9c8db8 ("x86/devicetree: Use CPU description from Device Tree") Cc: stable <stable(a)vger.kernel.org> # 4.17 Signed-off-by: Johan Hovold <johan(a)kernel.org> --- Thomas, Hope this looks better to you. My use case for this is still out-of-tree, but since CPU-node lookup is generic functionality and with observable impact also for mainline users (sysfs) I added a stable tag.
