2014-08-04video: hyperv: hyperv_fb: refresh the VM screen by force on VM panicDexuan Cui
Currently the VSC has no chance to notify the VSP of the dirty rectangle on VM panic because the notification work is done in a workqueue, and in panic() the kernel typically ends up in an infinite loop, and a typical kernel config has CONFIG_PREEMPT_VOLUNTARY=y and CONFIG_PREEMPT is not set, so a context switch can't happen in panic() and the workqueue won't have a chance to run. As a result, the VM Connection window can't refresh until it's closed and we re-connect to the VM. We can register a handler on panic_notifier_list: the handler can notify the VSC and switch the framebuffer driver to a "synchronous mode", meaning the VSC flushes any future framebuffer change to the VSP immediately. v2: removed the MS-TFS line in the commit message v3: remove some 'unlikely' markings v4: avoid global variables as Tomi Valkeinen suggested Cc: Haiyang Zhang <haiyangz@microsoft.com> Signed-off-by: Dexuan Cui <decui@microsoft.com> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>

2014-07-28video: clcd-versatile: Depend on ARMMark Brown
The Versatile CLCD helpers call dma_alloc_writecombine() which is only available on ARM and AVR32, meaning they won't build on other platforms including arm64. Unfortunately the current Kconfig enables the symbol by default if ARCH_VEXPRESS is defined which means that it is enabled on arm64 when building for the ARM reference platforms and models for ARMv8 since they have many hardware similarities with their pre-ARMv8 systems. Since all the systems that need the helpers are ARM systems fix this by adding a dependency on ARM. Signed-off-by: Mark Brown <broonie@linaro.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>

2014-07-23video: fix up versatile CLCD helper moveArnd Bergmann
commit 11c32d7b6274cb0f ("video: move Versatile CLCD helpers") moved files out of the plat-versatile directory but in the process got a few of the dependencies wrong: - If CONFIG_FB is not set, the file no longer gets built, resulting in a link error - If CONFIG_FB or CONFIG_FB_ARMCLCD are disabled, we also get a Kconfig warning for incorrect dependencies due to the symbol being 'select'ed from the platform Kconfig. - When the file is not built, we also get a link error for missing symbols. This patch should fix all three, by removing the 'select' statements, changing the Kconfig description of the symbol to be enabled in exactly the right configurations, and adding inline stub functions for the case when the framebuffer driver is disabled.

2014-07-10x86, ia64: Move EFI_FB vga_default_device() initialization to pci_vga_fixup()Bruno Prémont
Commit b4aa0163056b ("efifb: Implement vga_default_device() (v2)") added efifb vga_default_device() so EFI systems that do not load shadow VBIOS or setup VGA get proper value for boot_vga PCI sysfs attribute on the corresponding PCI device. Xorg doesn't detect devices when boot_vga=0, e.g., on some EFI systems such as MacBookAir2,1. Xorg detects the GPU and finds the DRI device but then bails out with "no devices detected". Note: When vga_default_device() is set boot_vga PCI sysfs attribute reflects its state. When unset this attribute is 1 whenever IORESOURCE_ROM_SHADOW flag is set. With introduction of sysfb/simplefb/simpledrm efifb is getting obsolete while having native drivers for the GPU also makes selecting sysfb/efifb optional. Remove the efifb implementation of vga_default_device() and initialize vgaarb's vga_default_device() with the PCI GPU that matches boot screen_info in pci_fixup_video().

Since v2.6.7 the 68328 frame buffer driver contains a check for CONFIG_FB_68328_INVERT. But the Kconfig symbol FB_68328_INVERT was never added to the tree. Remove this check and do some related cleaning up. Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
