2009-05-15sysrq, intel_fb: fix sysrq g collisionJason Wessel1-2/+2
Commit 79e539453b34e35f39299a899d263b0a1f1670bd introduced a regression where you cannot use sysrq 'g' to enter kgdb. The solution is to move the intel fb sysrq over to V for video instead of G for graphics. The SMP VOYAGER code to register for the sysrq-v is not anywhere to be found in the mainline kernel, so the comments in the code were cleaned up as well. This patch also cleans up the sysrq definitions for kgdb to make it generic for the kernel debugger, such that the sysrq 'g' can be used in the future to enter a gdbstub or another kernel debugger.

2009-05-14drm/i915: Add new GET_PIPE_FROM_CRTC_ID ioctl.Carl Worth3-0/+34
This allows userlevel code to discover the pipe number corresponding to a given CRTC ID. This is necessary for doing pipe-specific operations such as waiting for vblank on a given CRTC. Failure to use the right pipe mapping can result in GPU hangs, or at least failure to actually sync to vblank.

2009-05-14drm/i915: Set HDMI hot plug interrupt enable for only the output in question.Ma Ling1-5/+12
We detect HDMI output connection status by writing to HOT Plug Interrupt Detect Enable bit in PORT_HOTPLUG_EN. The behavior will generate a specified interrupt, which is caught by audio driver, but during one detection driver set all Detect Enable bits of HDMIB, HDMIC HDMID, and generate wrong interrupt signals for current output, according to the signals audio driver misunderstand device status. The patch intends to handle corresponding output precisely. It fixed freedesktop.org bug #21371 Signed-off-by: Ma Ling <ling.ma@intel.com> Signed-off-by: Eric Anholt <eric@anholt.net>

2009-05-14drm/i915: ignore LVDS on intel graphics systems that lie about having itJarod Wilson1-8/+46
There are a number of small form factor desktop systems with Intel mobile graphics chips that lie and say they have an LVDS. With kernel mode-setting, this becomes a problem, and makes native resolution boot go haywire -- for example, my Dell Studio Hybrid, hooked to a 1920x1080 display claims to have a 1024x768 LVDS, and the resulting graphical boot on the 1920x1080 display uses only the top left 1024x768, and auto-configured X will end up only 1024x768 as well. With this change, graphical boot and X both do 1920x1080 as expected. Note that we're simply embracing and extending the early bail-out code in place for the Mac Mini here. The xorg intel driver uses pci subsystem device and vendor id for matching, while we're using dmi lookups here. The MSI addition is courtesy of and tested by Bill Nottingham.

2009-05-14drm/i915: sanity check IER at wait_request timeJesse Barnes1-0/+9
We might sleep here anyway so I hope an extra uncached read is ok to add. In #20896 we found that vbetool clobbers the IER. In KMS mode this is particularly bad since we don't set the interrupt regs late (in EnterVT), so we'd fail to get *any* interrupts at all after X started (since some distros have scripts that call vbetool at X startup apparently). So this patch checks IER at wait_request time, and re-enables interrupts if it's been clobbered. In a proper config this check should never be triggered. This is really a distro issue, but having a sanity check is nice, as long as it doesn't have a real performance hit.

Save the bit 17 state of the pages when freeing the page list, and reswizzle them if necessary when rebinding the pages (in case they were swapped out). Since we have userland with expectations that the swizzle enums let it pread and pwrite contents accurately, we can't expose a new swizzle enum for bit 17 (which it would have to GTT map to handle), so we handle it down in pread and pwrite by swizzling the copy when bit 17 of the page address is set.

We also expose another debugfs node (i915_ringbuffer_info) with information on the state (i.e. head, tail addresses) of the ringbuffer.
