* intelfb: add vsync interrupt supportEric Hustvedt2006-07-031-0/+33
| | | | | | | | [04/05] intelfb: implement FBIO_WAITFORVSYNC ioctl The (unofficial) FBIO_WAITFORVSYNC ioctl is implemented by sleeping on the appropriate waitqueue, as defined in my earlier patch. Currently, only display 0 (aka pipe A) is supported. Signed-off-by: Eric Hustvedt <ehustvedt@cecropia.com>
* intelfb: add vsync interrupt supportEric Hustvedt2006-07-031-0/+76
| | | | | | | | | | | | [03/05] intelfb: Implement basic interrupt handling Functions have been added to enable and disable interrupts using the MMIO registers. Currently only pipe A vsync interrupts are enabled. A generalized vsync accounting struct is defined, with the intent that it can encapsulate per-pipe vsync related info in the future. Currently a single instance is hard-coded. The interrupt service routine currently only looks for vsync interrupts on pipe A, and increments a counter and wakes up anyone waiting on it. This implementation is heavily influenced by similar implementations in the atyfb and matroxfb drivers. Signed-off-by: Eric Hustvedt <ehustvedt@cecropia.com>
* intelfb: add vsync interrupt supportEric Hustvedt2006-07-031-0/+9
| | | | | | | | | | [02/05] intelfb: Add interrupt related register definitions Add constants for accessing HWSTAM, IER, IIR, and IMR registers. Add constants for interrupt types supported by the 8xx and 9xx chipsets. The registers are also stored in the hwstate struct and dumped in the debug routine.

* [PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reasonOlaf Hering2005-11-091-1/+0
| | | | | | | | | | | | | | | | | | | | | This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
