Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources. [akpm@osdl.org: sparc64 fix] Signed-off-by:

Add the PS3 Virtual Frame Buffer Driver. As the actual graphics hardware cannot be accessed directly by Linux, ps3fb uses a virtual frame buffer in main memory. The actual screen image is copied to graphics memory by the GPU on every vertical blank, by making a hypervisor call. Signed-off-by:

Preallocate bootmem memory for the PS3 frame buffer device, which needs a large block of physically-contiguous memory. The size of this memory block is configurable: - The config option CONFIG_FB_PS3_DEFAULT_SIZE_M allows to specify the default amount of memory (in MiB) allocated to the virtual frame buffer. - The early boot parameter `ps3fb=xxx' allows to override the default value. It will be rounded up to a multiple of 1 MiB, if needed.

fb_videomode_to_var(): reset the virtual screen parameters when converting from an fb_videomode to an fb_var_screeninfo. Without this the old virtual screen parameters are kept. Hence you cannot switch to a video mode with a lower resolution on frame buffer devices that don't support virtual screens and panning, as values are not supposed to be rounded down when they don't fit. I also reordered the assignments to match the order of the individual members. Signed-off-by:

Some of fb drivers uses atomic_t in bad manner, since there are still some race-prone gaps. Use mutexes to protect open/close code sections with ref_count testing and finally use simple uint. Signed-off-by:

The FB_S3TRIO driver: - has been marked as BROKEN for more than two years and - is still marked as BROKEN. Drivers that had been marked as BROKEN for such a long time seem to be unlikely to be revived in the forseeable future. But if anyone wants to ever revive this driver, the code is still present in the older kernel releases. Signed-off-by:

The 32-plane variations of the TGA use the Bt463 RAMDAC and are therefore DirectColor rather than TrueColor adapters. This is a set of changes to implement the necessary bits to support this model. A couple of fixes to fix accesses to the RAMDAC are included as a side-effect. Signed-off-by:

Add a driver for S3 Trio / S3 Virge. Driver is tested with most versions of S3 Trio and with S3 Virge/DX, on i386. (akpm: We kind-of have support for this hardware already, but... virgefb.c - amiga/zorro specific, - broken (according to Kconfig), - uses obsolete/nonexistent interface (struct display_switch) - recent Adrian Bunk's patch removes this driver S3triofb.c - ppc/openfirmware specific - minimal functionality - broken (according to Kconfig), - uses obsolete/nonexistent interface (struct display_switch) ) Signed-off-by:

On hotplug, we execute the hardware extension enable sequence. On unplug, we decache any vcpus that last ran on the exiting cpu, and execute the hardware extension disable sequence. Signed-off-by:

Like the inline code it replaces, this function decaches the vmcs from the cpu it last executed on. in addition: - vcpu_clear() works if the last cpu is also the cpu we're running on - it is faster on larger smps by virtue of using smp_call_function_single() Includes fix from Ingo Molnar.

This will allow us to iterate over all vcpus and see which cpus they are running on. [akpm@osdl.org: use standard (ugly) initialisers] Signed-off-by:

Avi Kivity authored
The following patchset allows a host with running virtual machines to be suspended and, on at least a subset of the machines tested, resumed. Note that this is orthogonal to suspending and resuming an individual guest to a file. A side effect of implementing suspend/resume is that cpu hotplug is now supported. This should please the owners of big iron. This patch: KVM wants the cpu hotplug notifications, both for cpu hotplug itself, but more commonly for host suspend/resume. In order to avoid extensive #ifdefs, provide stubs when CONFIG_CPU_HOTPLUG is not defined. In all, we have four cases: - UP: register and unregister stubbed out - SMP+hotplug: full register and unregister - SMP, no hotplug, core: register as __init, unregister stubbed (cpus are brought up during core initialization) - SMP, no hotplug, module: register and unregister stubbed out (cpus cannot be brought up during module lifetime) Signed-off-by: -

vcpu_load() can return NULL and it sometimes does in failure paths (for example when the userspace ABI version is too old) - causing a preemption count underflow in the ->vcpu_free() later on. So check for NULL. Signed-off-by:
