* Revert "drm/i915/crt: Do not rely upon the HPD presence pin"Linus Torvalds2012-06-081-5/+3
| | | | | | | | | | | | | | | | | | | | | This reverts commit 9e612a008fa7fe493a473454def56aa321479495. It incorrectly finds VGA connectors where none are attached, apparently not noticing that nothing replied to the EDID queries, and happily using the default EDID modes that have nothing to do with actual hardware. That in turn then causes X to fall down to the lowest common denominator, which is usually the default 1024x768 mode that is in the default EDID and pretty much anything supports). I'd suggest that if not relying on the HDP pin, the code should at least check whether it gets valid EDID data back, rather than just assume there's something on the VGA connector.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The encoder get_crtc operation is called to retrieve a pointer to the CRTC the encoder is currenctly connected to, right after setting the encoder::crtc field to the new CRTC. The implementation of this operation returns the pointer to the new CRTC, which is then pointlessly compared to itself. As the operation is not mandatory, don't implement it.

Holding forcewake around this register init sequences makes chip reset reliable again. Note that this is not the first such issue: commit f01db988ef6f6c70a6cc36ee71e4a98a68901229 Author: Sean Paul <seanpaul@chromium.org> Date: Fri Mar 16 12:43:22 2012 -0400 drm/i915: Add wait_for in init_ring_common added delay loops to make RING_START and RING_CTL initialization reliable on the blt ring at boot-up. So I guess it won't hurt if we do this unconditionally for all force_wake needing gpus. To avoid copy&pasting of the HAS_FORCE_WAKE check I've added a new intel_info bit for that. v2: Fixup missing commas in static struct and properly handling the error case in init_ring_common, both noticed by Jani Nikula.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By correctly describing the rinbuffers as being in the GTT domain, it appears that we are more careful with the management of the CPU cache upon resume and so prevent some coherency issue when submitting commands to the GPU later. A secondary effect is that the debug logs are then consistent with the actual usage (i.e. they no longer describe the ringbuffers as being in the CPU write domain when we are accessing them through an wc iomapping.)

In this instance, we were failing to reset the cached value of ring->last_retired_head and so upon the first request for more space following a resume would potentially (depending on a narrow race window) believe that the HEAD had advanced much further than reality.

| * | drm/i915: tune down the noise of the RP irq limit failDaniel Vetter2012-05-251-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We still don't understand why this fails exactly, but if fails way too often for a simple debug information. Furthermore the current ducttape should prevent the gpu from getting stuck at low frequencies. Hence tune down the dmesg noise. Note that the known failure case is that the register read returns 0 when the gpu gets confused. v2: Add comments about the known failure case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Broadwater and Crestline share a limitation that prevent it from relocating general surface state above 4GiB. The only recourse we have since any buffer object may be used as a relocation target is then to limit all object allocations on 965g[m] to DMA32.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Media turbo requests can either use RPVSWREQ or RPNSWREQ to indicate what the interrupt handler should do. Since we only deal with the latter in our turbo code, make the media engine use that for turbo requests. Cc: stable@vger.kernel.org.

So don't bother and just reject these modes.
