[media] v4l2_plane_pix_format: use u32 bytesperline instead of u16

2015-04-03T02:54:47+00:00

While running v4l2-compliance tests on vivid I suddenly got errors due to a call to vmalloc_user with size 0 from vb2. Digging deeper into the cause I discovered that this was due to the fact that struct v4l2_plane_pix_format defines bytesperline as a __u16 instead of a __u32. The test I was running selected a format of 4 * 4096 by 4 * 2048 with a 32 bit pixelformat. So bytesperline was 4 * 4 * 4096 = 65536, which becomes 0 in a __u16. And bytesperline * height is suddenly 0 as well. While the vivid driver may be a virtual driver, it is to be expected that this limit will be hit for real hardware as well in the near future: 8k deep-color video will already reach it. The solution is to change the type to __u32. The only drivers besides vivid that use the multiplanar API are little-endian ARM and SH platforms (exynos, ti-vpe, vsp1), so this is safe.

[media] s5p-tv: hdmi needs I2C support

2015-03-04T11:59:14+00:00

Building the s5p-tv HDMI support when CONFIG_I2C is disabled gives us this build error: s5p-tv/hdmi_drv.c: In function 'hdmi_probe': s5p-tv/hdmi_drv.c:947:2: error: implicit declaration of function 'i2c_get_adapter' [-Werror=implicit-function-declaration] adapter = i2c_get_adapter(pdata->hdmiphy_bus); ^ This patch changes the Kconfig description to include I2C as a dependency for this driver, so it cannot be configured incorrectly.

[media] media: s5p-tv: use vb2_ops_wait_prepare/finish helper

2014-12-22T16:35:52+00:00

This patch drops driver specific wait_prepare() and wait_finish() callbacks from vb2_ops and instead uses the the helpers vb2_ops_wait_prepare/finish() provided by the vb2 core, the lock member of the queue needs to be initalized to a mutex so that vb2 helpers vb2_ops_wait_prepare/finish() can make use of it.

Pull more ACPI and power management updates from Rafael Wysocki: "These are regression fixes (leds-gpio, ACPI backlight driver, operating performance points library, ACPI device enumeration messages, cpupower tool), other bug fixes (ACPI EC driver, ACPI device PM), some cleanups in the operating performance points (OPP) framework, continuation of CONFIG_PM_RUNTIME elimination, a couple of minor intel_pstate driver changes, a new MAINTAINERS entry for it and an ACPI fan driver change needed for better support of thermal management in user space. Specifics: - Fix a regression in leds-gpio introduced by a recent commit that inadvertently changed the name of one of the properties used by the driver (Fabio Estevam). - Fix a regression in the ACPI backlight driver introduced by a recent fix that missed one special case that had to be taken into account (Aaron Lu). - Drop the level of some new kernel messages from the ACPI core introduced by a recent commit to KERN_DEBUG which they should have used from the start and drop some other unuseful KERN_ERR messages printed by ACPI (Rafael J Wysocki). - Revert an incorrect commit modifying the cpupower tool (Prarit Bhargava). - Fix two regressions introduced by recent commits in the OPP library and clean up some existing minor issues in that code (Viresh Kumar). - Continue to replace CONFIG_PM_RUNTIME with CONFIG_PM throughout the tree (or drop it where that can be done) in order to make it possible to eliminate CONFIG_PM_RUNTIME (Rafael J Wysocki, Ulf Hansson, Ludovic Desroches). There will be one more "CONFIG_PM_RUNTIME removal" batch after this one, because some new uses of it have been introduced during the current merge window, but that should be sufficient to finally get rid of it. - Make the ACPI EC driver more robust against race conditions related to GPE handler installation failures (Lv Zheng). - Prevent the ACPI device PM core code from attempting to disable GPEs that it has not enabled which confuses ACPICA and makes it report errors unnecessarily (Rafael J Wysocki). - Add a "force" command line switch to the intel_pstate driver to make it possible to override the blacklisting of some systems in that driver if needed (Ethan Zhao). - Improve intel_pstate code documentation and add a MAINTAINERS entry for it (Kristen Carlson Accardi). - Make the ACPI fan driver create cooling device interfaces witn names that reflect the IDs of the ACPI device objects they are associated with, except for "generic" ACPI fans (PNP ID "PNP0C0B"). That's necessary for user space thermal management tools to be able to connect the fans with the parts of the system they are supposed to be cooling properly.
