[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.

It means that tlbs_dirty is always used as int and the higher 32 bits is useless. We need to check tlbs_dirty in a correct way and this change checks it directly without propagating it to need_tlb_flush. Note: it's _extremely_ unlikely this neglecting of higher 32 bits can cause problems in practice. It would require encountering tlbs_dirty on a 4 billion count boundary, and KVM would need to be using shadow paging or be running a nested guest.

[PATCH] iio:adc:stm32-adc: Add HAS_IOMEM dependency

by Jonathan Cameron

From: Jonathan Cameron <Jonathan.Cameron(a)huawei.com> Seems that there are config combinations in which this driver gets enabled and hence selects the MFD, but with out HAS_IOMEM getting pulled in via some other route. MFD is entirely contained in an if HAS_IOMEM block, leading to the build issue in this bugzilla. https://bugzilla.kernel.org/show_bug.cgi?id=209889 Cc: <Stable(a)vger.kernel.org> Signed-off-by: Jonathan Cameron <Jonathan.Cameron(a)huawei.com> --- drivers/iio/adc/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/iio/adc/Kconfig b/drivers/iio/adc/Kconfig index bf7d22fa4be2..6605c263949c 100644 --- a/drivers/iio/adc/Kconfig +++ b/drivers/iio/adc/Kconfig @@ -923,6 +923,7 @@ config STM32_ADC_CORE depends on ARCH_STM32 || COMPILE_TEST depends on OF depends on REGULATOR + depends on HAS_IOMEM select IIO_BUFFER select MFD_STM32_TIMERS select IIO_STM32_TIMER_TRIGGER -- 2.30.0

It means that tlbs_dirty is always used as int and the higher 32 bits is useless. We need to check tlbs_dirty in a correct way and this change checks it directly without propagating it to need_tlb_flush. Note: it's _extremely_ unlikely this neglecting of higher 32 bits can cause problems in practice. It would require encountering tlbs_dirty on a 4 billion count boundary, and KVM would need to be using shadow paging or be running a nested guest.
