2014-04-30drm/radeon: call drm_edid_to_eld when we update the edidAlex Deucher1-0/+1
commit 16086279353cbfecbb3ead474072dced17b97ddc upstream. This needs to be done to update some of the fields in the connector structure used by the audio code. Noticed by several users on irc.

commit aa6de142c901cd2d90ef08db30ae87da214bedcc upstream. Previously, the vmwgfx_fb driver would allow users to call FBIOSET_VINFO, but it would not adjust the FINFO properly, resulting in distorted screen rendering. The patch corrects that behaviour.

commit 91f3a6aaf280294b07c05dfe606e6c27b7ba3c72 upstream. The OUTPUT_ENABLE action jumps past the point in the coder where the data_offset is set on certain rs780 cards. This worked previously because the OUTPUT_ENABLE action is always called immediately after the ENABLE action so the data_offset remained set. In 6f8bbaf568c7f2c497558bfd04654c0b9841ad57 (drm/radeon/atom: initialize more atom interpretor elements to 0), we explictly reset data_offset to 0 between atom calls which then caused this to fail. The fix is to just skip calling the OUTPUT_ENABLE action on the problematic chipsets. The ENABLE action does the same thing and more. Ultimately, we could probably drop the OUTPUT_ENABLE action all together on DCE3 asics. fixes: https://bugzilla.kernel.org/show_bug.cgi?id=60791 v2: only rs880 seems to be affected Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Ben Hutchings <ben@decadent.org.uk>
2013-10-27drm/i915: try not to lose backlight CBLV precisionJani Nikula1-1/+1
commit cac6a5ae0118832936eb162ec4cedb30f2422bcc upstream. ACPI has _BCM and _BQC methods to set and query the backlight brightness, respectively. The ACPI opregion has variables BCLP and CBLV to hold the requested and current backlight brightness, respectively. The BCLP variable has range 0..255 while the others have range 0..100. This means the _BCM method has to scale the brightness for BCLP, and the gfx driver has to scale the requested value back for CBLV. If the _BQC method uses the CBLV variable (apparently some implementations do, some don't) for current backlight level reporting, there's room for rounding errors. Use DIV_ROUND_UP for scaling back to CBLV to get back to the same values that were passed to _BCM, presuming the _BCM simply uses bclp = (in * 255) / 100 for scaling to BCLP.

2013-09-10drm/i915: Invalidate TLBs for the rings after a resetChris Wilson2-0/+15
commit 884020bf3d2a3787a1cc6df902e98e0eec60330b upstream. After any "soft gfx reset" we must manually invalidate the TLBs associated with each ring. Empirically, it seems that a suspend/resume or D3-D0 cycle count as a "soft reset". The symptom is that the hardware would fail to note the new address for its status page, and so it would continue to write the shadow registers and breadcrumbs into the old physical address (now used by something completely different, scary). Whereas the driver would read the new status page and never see any progress, it would appear that the GPU hung immediately upon resume.

2013-09-10drm/i915/lvds: ditch ->prepare special caseDaniel Vetter1-7/+1
commit 520c41cf2fa029d1e8b923ac2026f96664f17c4b upstream. LVDS is the first output where dpms on/off and prepare/commit don't perfectly match. Now the idea behind this special case seems to be that for simple resolution changes on the LVDS we don't need to stop the pipe, because (at least on newer chips) we can adjust the panel fitter on the fly. There are a few problems with the current code though: - We still stop and restart the pipe unconditionally, because the crtc helper code isn't flexible enough. - We show some ugly flickering, especially when changing crtcs (this the crtc helper would actually take into account, but we don't implement the encoder->get_crtc callback required to make this work properly). So it doesn't even work as advertised. I agree that it would be nice to do resolution changes on LVDS (and also eDP) whithout blacking the screen where the panel fitter allows to do that. But imo we should implement this as a special case a few layers up in the mode set code, akin to how we already detect simple framebuffer changes (and only update the required registers with ->mode_set_base). Until this is all in place, make our lives easier and just rip it out. Also note that this seems to fix actual bugs with enabling the lvds output, see: http://lists.freedesktop.org/archives/intel-gfx/2012-July/018614.html Cc: Takashi Iwai <tiwai@suse.de> Cc: Giacomo Comes <comes@naic.edu> Acked-by: Chris Wilson <chris@chris-wilson.co.uk> Tested-by: Takashi Iwai <tiwai@suse.de> Signed-Off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Ben Hutchings <ben@decadent.org.uk>

2013-08-03drm/radeon: fix combios tables on older cardsMark Kettenis1-104/+41
commit cef1d00cd56f600121ad121875655ad410a001b8 upstream. Noticed that my old Radeon 7500 hung after printing drm: GPU not posted. posting now... when it wasn't selected as the primary card the BIOS. Some digging revealed that it was hanging in combios_parse_mmio_table() while parsing the ASIC INIT 3 table. Looking at the BIOS ROM for the card, it becomes obvious that there is no ASIC INIT 3 table in the BIOS. The code is just processing random garbage. No surprise it hangs! Why do I say that there is no ASIC INIT 3 table is the BIOS? This table is found through the MISC INFO table. The MISC INFO table can be found at offset 0x5e in the COMBIOS header. But the header is smaller than that. The COMBIOS header starts at offset 0x126. The standard PCI Data Structure (the bit that starts with 'PCIR') lives at offset 0x180. That means that the COMBIOS header can not be larger than 0x5a bytes and therefore cannot contain a MISC INFO table. I looked at a dozen or so BIOS images, some my own, some downloaded from: <http://www.techpowerup.com/vgabios/index.php?manufacturer=ATI&page=1> It is fairly obvious that the size of the COMBIOS header can be found at offset 0x6 of the header. Not sure if it is a 16-bit number or just an 8-bit number, but that doesn't really matter since the tables seems to be always smaller than 256 bytes. So I think combios_get_table_offset() should check if the requested table is present. This can be done by checking the offset against the size of the header. See the diff below. The diff is against the WIP OpenBSD codebase that roughly corresponds to Linux 3.8.13 at this point. But I don't think this bit of the code changed much since then.

2013-06-19drm/i915: prefer VBT modes for SVDO-LVDS over EDIDDaniel Vetter1-4/+6
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.

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

2013-06-19radeon: Fix system hang issue when using KMS with older cardsAdis Hamzić12-41/+72
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 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.
