2013-06-20drm/nv50/kms: use dac loadval from vbios, where it's availableBen Skeggs
commit d40ee48acde16894fb3b241d7e896d5fa84e0f10 upstream. Regression from merging the old nv50/nvd9 code together, and may be needed to fully fix fdo#64904.

2013-06-20drm/i915: prefer VBT modes for SVDO-LVDS over EDIDDaniel Vetter
commit c3456fb3e4712d0448592af3c5d644c9472cd3c1 upstream. In commit 53d3b4d7778daf15900867336c85d3f8dd70600c Author: Egbert Eich <eich@suse.de> Date: Tue Jun 4 17:13:21 2013 +0200 drm/i915/sdvo: Use &intel_sdvo->ddc instead of intel_sdvo->i2c for DDC Egbert Eich fixed a long-standing bug where we simply used a non-working i2c controller to read the EDID for SDVO-LVDS panels. Unfortunately some machines seem to not be able to cope with the mode provided in the EDID. Specifically they seem to not be able to cope with a 4x pixel mutliplier instead of a 2x one, which seems to have been worked around by slightly changing the panels native mode in the VBT so that the dotclock is just barely above 50MHz. Since it took forever to notice the breakage it's fairly safe to assume that at least for SDVO-LVDS panels the VBT contains fairly sane data. So just switch around the order and use VBT modes first. v2: Also add EDID modes just in case, and spell Egbert correctly. v3: Elaborate a bit more about what's going on on Chris' machine.

2013-06-13drm/i915: force full modeset if the connector is in DPMS OFF modeImre Deak
commit e3de42b68478a8c95dd27520e9adead2af9477a5 upstream. Currently the driver's assumed behavior for a modeset with an attached FB is that the corresponding connector will be switched to DPMS ON mode if it happened to be in DPMS OFF (or another power save mode). This wasn't enforced though if only the FB changed, everything else (format, connector etc.) remaining the same. In this case we only set the new FB base and left the connector in the old power save mode. Fix this by forcing a full modeset whenever there is an attached FB and any affected connector is in a power save mode. V_2: Run the test for encoders in power save mode outside the the test for fb change: user space may have just disabled the encoders but left everything else in place. Make sure the connector list is not empty before running this test.

2013-06-13drm/i915: Fix spurious -EIO/SIGBUS on wedged gpusDaniel Vetter
commit 7abb690a0e095717420ba78dcab4309abbbec78a upstream. Chris Wilson noticed that since commit 1f83fee08d625f8d0130f9fe5ef7b17c2e022f3c [v3.9] Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Nov 15 17:17:22 2012 +0100 drm/i915: clear up wedged transitions X can again get -EIO when it does not expect it. And even worse score a SIGBUS when accessing gtt mmaps. The established ABI is that we _only_ return an -EIO from execbuf - all other ioctls should just work. And since the reset code moves all bos out of gpu domains and clears out all the last_seqno/ring tracking there really shouldn't be any reason for non-execbuf code to ever touch the hw and see an -EIO. After some extensive discussions we've noticed that these spurios -EIO are caused by i915_gem_wait_for_error: http://www.mail-archive.com/intel-gfx@lists.freedesktop.org/msg20540.html That is easy to fix by returning 0 instead of -EIO, since grabbing the dev->struct_mutex does not yet mean that we actually want to touch the hw. And so there is no reason at all to fail with -EIO. But that's not the entire since, since often (at least it's easily googleable) dmesg indicates that the reset fails and we declare the gpu wedged. Then, quite a bit later X wakes up with the "Timed out waiting for the gpu reset to complete" DRM_ERROR message in wait_for_errror and brings down the desktop with an -EIO/SIGBUS. So clearly we're missing a wakeup somewhere, since the gpu reset just doesn't take 10 seconds to complete. And indeed we're do handle the terminally wedged state wrong. Fix this all up.

commit 53d3b4d7778daf15900867336c85d3f8dd70600c upstream. In intel_sdvo_get_lvds_modes() the wrong i2c adapter record is used for DDC.

2013-06-13drm: fix a use-after-free when GPU acceleration disabledHuacai Chen
commit b7ea85a4fed37835eec78a7be3039c8dc22b8178 upstream. When GPU acceleration is disabled, drm_vblank_cleanup() will free the vblank-related data, such as vblank_refcount, vblank_inmodeset, etc. But we found that drm_vblank_post_modeset() may be called after the cleanup, which use vblank_refcount and vblank_inmodeset. And this will cause a kernel panic. Fix this by return immediately if dev->num_crtcs is zero. This is the same thing that drm_vblank_pre_modeset() does.

2013-06-13radeon: Fix system hang issue when using KMS with older cardsAdis Hamzić
commit e49f3959a96dc279860af7e86e6dbcfda50580a5 upstream. The current radeon driver initialization routines, when using KMS, are written so that the IRQ installation routine is called before initializing the WB buffer and the CP rings. With some ASICs, though, the IRQ routine tries to access the GFX_INDEX ring causing a call to RREG32 with the value of -1 in radeon_fence_read. This, in turn causes the system to completely hang with some cards, requiring a hard reset. A call stack that can cause such a hang looks like this (using rv515 ASIC for the example here): * rv515_init (rv515.c) * radeon_irq_kms_init (radeon_irq_kms.c) * drm_irq_install (drm_irq.c) * radeon_driver_irq_preinstall_kms (radeon_irq_kms.c) * rs600_irq_process (rs600.c) * radeon_fence_process - due to SW interrupt (radeon_fence.c) * radeon_fence_read (radeon_fence.c) * hang due to RREG32(-1) The patch moves the IRQ installation to the card startup routine, after the ring has been initialized, but before the IRQ has been set. This fixes the issue, but requires a check to see if the IRQ is already installed, as is the case in the system resume codepath. I have tested the patch on three machines using the rv515, the rv770 and the evergreen ASIC. They worked without issues. This seems to be a known issue and has been reported on several bug tracking sites by various distributions (see links below). Most of reports recommend booting the system with KMS disabled and then enabling KMS by reloading the radeon module. For some reason, this was indeed a usable workaround, however, UMS is now deprecated and disabled by default.

commit 9f1d036648c1c5ed81b0e98d7a06d55df972701e upstream. Higher bits of the base address of framebuffers weren't being programmed properly. This caused framebuffers that didn't happen to be allocated at a low enough address to not be displayed properly.

2013-05-19drm/mgag200: Fix writes into MGA1064_PIX_CLK_CTL registerChristopher Harvey
commit fb70a6690875315a3a1454e52fa339441ee7612b upstream. The original line, WREG_DAC(MGA1064_PIX_CLK_CTL_CLK_DIS, tmp); wrote tmp into MGA1064_PIX_CLK_CTL_CLK_DIS, where MGA1064_PIX_CLK_CTL_CLK_DIS is an offset into MGA1064_PIX_CLK_CTL. Change the line to write properly into MGA1064_PIX_CLK_CTL. There were other chunks of code nearby that use the same pattern (but work correctly), so this patch updates them all to use this new (slightly more efficient) write pattern. The WREG_DAC macro was causing the DAC_INDEX register to be set to the same value twice. WREG8(DAC_DATA, foo) takes advantage of the fact that DAC_INDEX is already at the value we want.

2013-05-11drm/i915: correct the calculation of first_pd_entry_in_global_ptZhang, Xiong Y
commit 43b27290dd42b40f3f23f49677a7faa5a4eb1eff upstream. When ppgtt is enabled, dev_priv->gtt.total has excluded the gtt space occupied by ppgtt table in i915_gem_init_global_gtt() function. So the calculation of first_pd_entry_in_global_pt doesn't need to subtract I915_PPGTT_PD_ENTRIES again. Or else PPGTT directory table will be destroyed by global gtt allocation. This regression has been introduced in commit a54c0c279f3864171fe53c66e769d5a137c5c651 Author: Ben Widawsky <ben@bwidawsk.net> Date: Thu Jan 24 14:45:00 2013 -0800 drm/i915: remove intel_gtt structure The breakage is pretty subtile since the old gtt_total_entries included the pde range, whereas the new on did not.
