| * drm/i915: kick any firmware framebuffers before claiming the gttDaniel Vetter2012-07-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Iwai2012-07-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Deucher2012-06-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

Nope, I'm not nuts enough to write the 32bit ioctl compat layer for this and test it with some wine app. Even though hunting the ebay dungeons for a sis card actually supported by the mesa drivers casts some doubts on this ...

So do the same idlelock dance as for the other dma drivers and hope that papers over any issues. v2: Don't let the idlelock linger around.

I've fired up my i815 and now closing glxgears doesn't take 5 seconds anymore. \o/ The original problem with that was that I've moved it ahead in the series so that it could be included despite some patches not being ready quite yet.

This obviously needs a driver that doesn't switch off unused functions when regaining the VT. 3) When X controls the vt, we unplug that screen. Now drm_fb_helper_hotplug_event we noticed that that some crtcs are bound, but because we still have the fbcon on the 2nd screeen we also have bound set. Which means the fbcon wrongly assumes it's in control of everything an happily disables the output on the 2nd screen, but enables its fb on the first screen. Work around this issue by counting how many crtcs are bound and how many are bound to fbcon and assuming that when fbcon isn't bound to all of them, it better not touch the output configuration. Conceptually this is the same as only restoring the fbcon output configuration on the driver's ->lastclose, when we're sure that no one else is using kms. So this should be consistent with existing kms drivers. Chris has created a separate patch for the intel ddx, but I think we should fix this issue here regardless - the fbcon messing with the output config while it's not fully in control simply isn't a too polite behaviour.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When submitting a CONST_IB, emit a SWITCH_BUFFER packet before the CONST_IB. This isn't strictly necessary (the driver will work fine without it), but is good practice and allows for more flexible DE/CE sychronization options in the future. Current userspace drivers do not take advantage of the CE yet. v2: - clean up code flow a bit - no need to flush caches for CONST IB Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com>
