2008-02-20drm/i915: Fix hibernate save/restore of VGA attribute regsJesse Barnes1-0/+2
In hibernate, we may end up calling the VGA save regs function twice, so we need to make sure it's idempotent. That means leaving ARX in index mode after the first save operation. Fixes hibernate on 965. Signed-off-by: Dave Airlie <airlied@redhat.com>

2008-02-20drm/i915: restore pipeconf regs unconditionallyJesse Barnes1-7/+4
On many chipsets, the checks for DPLL enable or VGA mode will prevent the pipeconf regs from being restored, which could result in a blank display or X failing to come back after resume. So restore them unconditionally along with actually restoring pipe B's palette correctly. Signed-off-by: Dave Airlie <airlied@redhat.com>
2008-02-20drm/i915: save/restore interrupt stateJesse Barnes2-0/+12
On resume, if the interrupt state isn't restored correctly, we may end up with a flood of unexpected or ill-timed interrupts, which could cause the kernel to disable the interrupt or vblank events to happen at the wrong time.

2008-02-19fix historic ioremap() abuse in AGPArjan van dev Ven4-26/+26
Several AGP drivers right now use ioremap_nocache() on kernel ram in order to turn a page of regular memory uncached. There are two problems with this: 1) This is a total nightmare for the ioremap() implementation to keep various mappings of the same page coherent. 2) It's a total nightmare for the AGP code since it adds a ton of complexity in terms of keeping track of 2 different pointers to the same thing, in terms of error handling etc etc. This patch fixes this by making the AGP drivers use the new set_memory_XX APIs instead. Note: amd-k7-agp.c is built on Alpha too, and generic.c is built on ia64 as well, which do not yet have the set_memory_*() APIs, so for them some we have a few ugly #ifdefs - hopefully they'll be fixed soon.
