* video: fbdev: exynos: Remove old non-working MIPI driverKrzysztof Kozlowski2016-09-2713-3677/+0
| | | | | | | | | | | | | | The old non-DRM Exynos MIPI driver does not support DeviceTree and requires board files. Our platforms do not provide such so the driver is not usable since a long time ago. All features provided by the driver (and associated s6e8ax0 panel driver) are already supported by newer DRM version so the old code can be removed.

* video: fbdev: offb: Call pci_enable_device() before using the PCI VGA deviceYongji Xie2016-09-271-0/+15
| | | | | | | | | | | | Currently the offb module will use the PCI VGA device as frame buffer device without calling something like pci_enable_device(). However, this would cause some problem if we disable memory decoding of the upstream bridge before. When the console driver issued memory access to the VGA device, the access cannot be supported by the bridge which will cause EEH error on Power machine.

| | | | | | | | | | | | | Substitute home-brewed memory management for framebuffer memory with what core mm provide us: vmalloc_32_user() and remap_vmalloc_range() The former is designed to allocate virtually contiguous area which is 32bit addressable and zeroed so it can be mapped to userspace without leaking data. The latter does the similar job to remap_pfn_range() but additionally validate vmalloc'ed area and it's size.

* video: ARM CLCD: export symbols for driver moduleArnd Bergmann2016-08-302-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The amba-clcd-versatile.c code is always built-in and has to be done that way because it gets called by platform code that is also built-in. However, it now also gets called from the core CLCD driver through the .init_panel callback function, which leads to a build error when the framebuffer is configured as a loadable module: ERROR: "versatile_clcd_init_panel" [drivers/video/fbdev/amba-clcd-mod.ko] undefined! The same thing happens for the nomadik driver, although that could be linked into the core module if we want to: ERROR: "nomadik_clcd_init_panel" [drivers/video/fbdev/amba-clcd.ko] undefined! ERROR: "nomadik_clcd_init_board" [drivers/video/fbdev/amba-clcd.ko] undefined! For consistency, I'm taking the same approach in both cases here and just export the functions to make them usable by the driver. Alternatively, we could split out the CONFIG_OF-code from amba-clcd-versatile.c into a new file and link those two together with the core driver as one module.

* fbdev/efifb: Fix 16 color palette entry calculationMax Staudt2016-08-111-3/+3
| | | | | | | | | | | | | | | | | | | | | | When using efifb with a 16-bit (5:6:5) visual, fbcon's text is rendered in the wrong colors - e.g. text gray (#aaaaaa) is rendered as green (#50bc50) and neighboring pixels have slightly different values (such as #50bc78). The reason is that fbcon loads its 16 color palette through efifb_setcolreg(), which in turn calculates a 32-bit value to write into memory for each palette index. Until now, this code could only handle 8-bit visuals and didn't mask overlapping values when ORing them. With this patch, fbcon displays the correct colors when a qemu VM is booted in 16-bit mode (in GRUB: "set gfxpayload=800x600x16").

System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue created with create_singlethread_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantee unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. mipid_esd_stop_check () calls cancel_delayed_work() in mipid_cleanup() to ensure that there are no pending tasks while disconnecting the driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | In the .board_init() callback will set up a mux register in the Nomadik system controller. It so happens that the platform has two display output engines, and we have to poke a bit in a special register to make sure the right engine is muxed in as they are mutually exclusive. The Nomadik CLCD variant is instantiated on a platform where it is combined with a 800x480 TPO WVGA display. In the .panel_init() hook we will detect this display from the compatible string and set it up. We also add .enable() and .disable() callbacks for it as the sleep state is software controlled. The display is connected with a special 3-wire serial bus (this is sadly neither I2C or SPI) using three GPIO lines that we bitbang to detect the display and enable/disable sleep state.

| | | | | | | | | | | | | | | | | | | | | | | | | | The Nomadik variant has a few special quirks that need to be respected to make the driver work: - The block need to be clocked during writing of the TIMn registers or the bus will stall. - Special bits in the control register select how many of the output display lines get activated. - Special bits in the control register select how to manage the different 565 and 5551 modes. - There is a packed 24bit graphics mode, i.e 888 pixels can be stored in memory is three consecutive bytes, not evenly aligned to a 32bit word. This patch uses the vendor data pointer from the AMBA matching mechanism to track the quirks for this variant, and adds two hooks that variants can use to initialize boards and panels during start-up. These will later be used to adopt a Nomadik board profile.

| | | | | | | | | | | | | | | | | | | | | | | | The device tree bindings from display-timing.txt allows us to specify if data enable, hsync, vsync or the pixed clock should be inverted on the way to the display. The driver does not currently handle this so add support for those flags as it is needed for the Versatile Sanyo LCD display. Note that the previous behaviour was to invert the pixel clock for all displays, so unless the pixel clock polarity is explicitly defined in the device tree (i.e. the timings node has the "pixelclk-active" property) we fall back to inverting the pixel clock. This needs some extra compatibility code. Since the timing flags have to be set up inside the struct clcd_panel, we need to refactor the code a bit to pass around the panel rather than just the mode.

| | | | | | | | | | | | | | | | | | | The voltage changing code in this driver is broken and should be removed. The driver sets a single, exact voltage on probe. Unless there is a very good reason for this (which should be documented in comments) constraints like this need to be set via the machine constraints, voltage setting in a driver is expected to be used in cases where the voltage varies at runtime. In addition client drivers should almost never be calling regulator_can_set_voltage(), if the device needs to set a voltage it needs to set the voltage and the regulator core will handle the case where the regulator is fixed voltage. If the driver can skip setting the voltage it should just never set the voltage.

I have split Ville patch between zpos core and drivers version 5: - remove zpos range check and comeback to 0 to N-1 normalization algorithm version 4: - make sure that normalized zpos value is stay in the defined property range and warn user if not This patch adds support for generic plane's zpos property property with well-defined semantics: - added zpos properties to plane and plane state structures - added helpers for normalizing zpos properties of given set of planes - well defined semantics: planes are sorted by zpos values and then plane id value if zpos equals Normalized zpos values are calculated automatically when generic muttable zpos property has been initialized. Drivers can simply use plane_state->normalized_zpos in their atomic_check and/or plane_update callbacks without any additional calls to DRM core. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Compare to Marek's original patch zpos property is now specific to each plane and no more to the core. Normalize function take care of the range of per plane defined range before set normalized_zpos.

The container and fs parts both have acks from relevant experts. To use the new feature you have to add an F option to your binfmt_misc configuration" From the docs: "The usual behaviour of binfmt_misc is to spawn the binary lazily when the misc format file is invoked. However, this doesn't work very well in the face of mount namespaces and changeroots, so the F mode opens the binary as soon as the emulation is installed and uses the opened image to spawn the emulator, meaning it is always available once installed, regardless of how the environment changes" * tag 'binfmt-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/binfmt_misc: binfmt_misc: add F option description to documentation binfmt_misc: add persistent opened binary handler for containers fs: add filp_clone_open API
