* drm/i915: kick any firmware framebuffers before claiming the gttDaniel Vetter2012-07-031-7/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Especially vesafb likes to map everything as uc- (yikes), and if that mapping hangs around still while we try to map the gtt as wc the kernel will downgrade our request to uc-, resulting in abyssal performance. Unfortunately we can't do this as early as readon does (i.e. as the first thing we do when initializing the hw) because our fb/mmio space region moves around on a per-gen basis. So I've had to move it below the gtt initialization, but that seems to work, too. The important thing is that we do this before we set up the gtt wc mapping. Now an altogether different question is why people compile their kernels with vesafb enabled, but I guess making things just work isn't bad per se ... v2: - s/radeondrmfb/inteldrmfb/ - fix up error handling v3: Kill #ifdef X86, this is Intel after all. Noticed by Ben Widawsky. v4: Jani Nikula complained about the pointless bool primary initialization. v5: Don't oops if we can't allocate, noticed by Chris Wilson. v6: Resolve conflicts with agp rework and fixup whitespace. This is commit e188719a2891f01b3100d in drm-next. Backport to 3.5 -fixes queue requested by Dave Airlie - due to grub using vesa on fedora their initrd seems to load vesafb before loading the real kms driver. So tons more people actually experience a dead-slow gpu. Hence also the Cc: stable.

* drm: edid: Don't add inferred modes with higher resolutionTakashi Iwai2012-07-031-3/+24
| | | | | | | | | | | | | | | | | When a monitor EDID doesn't give the preferred bit, driver assumes that the mode with the higest resolution and rate is the preferred mode. Meanwhile the recent changes for allowing more modes in the GFT/CVT ranges give actually more modes, and some modes may be over the native size. Thus such a mode would be picked up as the preferred mode although it's no native resolution. For avoiding such a problem, this patch limits the addition of inferred modes by checking not to be greater than other modes. Also, it checks the duplicated mode entry at the same time.

* drm/radeon: fix VM page table setup on SIAlex Deucher2012-06-292-4/+13
| | | | | | | | | | | | | | | | | | | | | Cayman and trinity allow for variable sized VM page tables, but SI requires that all page tables be the same size. The current code assumes variablely sized VM page tables so SI may end up with part of each page table overlapping with other memory which could end up being interpreted by the VM hw as garbage. Change the code to better accomodate SI. Allocate enough space for at least 2 full page tables and always set last_pfn to max_pfn on SI so each VM is backed by a full page table. This limits us to only 2 VMs active at any given time on SI. This will be rectified and the code can be reunified once we move to two level page tables.

Still, we have reports of this being seen in the wild. Now Bspec has this little bit of lovely language in the PMIIR register: Public SNB Docs, Vol3Part2, 2.5.14 "PMIIR": "For each bit, the IIR can store a second pending interrupt if two or more of the same interrupt conditions occur before the first condition is cleared. Upon clearing the interrupt, the IIR bit will momentarily go low, then return high to indicate there is another interrupt pending." Now if we presume that PMIMR only prevent new interrupts from being queued, we could easily end up masking an interrupt and clearing it, but the 2nd pending interrupt setting the bit in PMIIR right away again. Which leads, the next time the irq handler runs, to hitting the WARN. Also, no bad side effects of this have ever been reported. And we've tracked down our issues with the gpu turbo getting stuck to bogus interrupt generation limits in th RPLIMIT register. So let's just rip out this WARN as bogus and call it a day. The only shallow thing here is that this 2-deep irq queue in the hw makes you wonder how racy the windows irq handler is ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nv_two_heads() was never meant to be used outside of pre-nv50 code. The code checks for >= NV_10 for 2 CRTCs, then downgrades a few specific chipsets to 1 CRTC based on (pci_device & 0x0ff0). The breakage example seen is on GTX 560Ti, with a pciid of 0x1200, which gets detected as an NV20 (0x020x) with 1 CRTC by nv_two_heads(), causing memory corruption because there's actually 2 CRTCs.. This switches fbcon to use the CRTC count directly from the mode_config structure, which will also fix the same issue on Kepler boards which have 4 CRTCs.

Issue is cause by ddx allocating bo with formula width*height*bpp while programming the GPU command stream with ALIGN(height, 8). In some case (where page alignment does not hide the extra size bo should be according to height alignment) the kernel will reject the command stream. This patch reprogram the command stream to slice - 1 (slice is a derivative value from height) which avoid rejecting the command stream while keeping the value of command stream checking from a security point of view. This patch also fix wrong computation of layer size for 2D tiled surface. Which should fix issue when 2D color tiling is enabled. This dump the radeon KMS_DRIVER_MINOR so userspace can know if they are on a fixed kernel or not. https://lkml.org/lkml/2012/6/3/80 https://bugs.freedesktop.org/show_bug.cgi?id=50892 https://bugs.freedesktop.org/show_bug.cgi?id=50857 !!!

* | 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.

Holding forcewake around this register init sequences makes chip reset reliable again.

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.

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.)
