2011-08-01drm/radeon/kms: fix for radeon on systems >4GB without hardware iommuDaniel Haid
commit 62fff811d73095bd95579d72f558f03c78f7914a upstream. On my x86_64 system with >4GB of ram and swiotlb instead of a hardware iommu (because I have a VIA chipset), the call to pci_set_dma_mask (see below) with 40bits returns an error. But it seems that the radeon driver is designed to have need_dma32 = true exactly if pci_set_dma_mask is called with 32 bits and false if it is called with 40 bits. I have read somewhere that the default are 32 bits. So if the call fails I suppose that need_dma32 should be set to true. And indeed the patch fixes the problem I have had before and which I had described here: http://choon.net/forum/read.php?21,106131,115940 Acked-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Andi Kleen <ak@linux.intel.com>
2011-08-01drm/i915: Add a no lvds quirk for the Asus EeeBox PC EB1007Hans de Goede
commit 6a574b5b9b186e28abd3e571dfd1700c5220b510 upstream. I found this while figuring out why gnome-shell would not run on my Asus EeeBox PC EB1007. As a standalone "pc" this device cleary does not have an internal panel, yet it claims it does. Add a quirk to fix this.

Revert drm/radeon/kms: properly compute group_size on 6xx/7xx From: Steve Conklin <sconklin@canonical.com> We discovered a regression for Radeon users in our latest proposed kernel for 2.6.35 (Maverick), and have isolated it to this patch: http://git.kernel.org/?p=linux/kernel/git/longterm/linux-2.6.35.y.git;a=commit;h=b8e9a4a45f8427837f4dba89 +bda4d4e3f3a5c726 We took that patch as part of 2.6.35.10, and one of our testers has reported that our build of that kernel also exhibits the problem.

2011-02-06drm/i915/dp: Fix I2C/EDID handling with active DisplayPort to DVI converterDavid Flynn
commit 8316f33766a82907c694267ff911e45e256f09f9 upstream. The DisplayPort standard (1.1a) states that: The I2C-over-AUX Reply field is valid only when Native AUX CH Reply field is AUX_ACK (00). When Native AUX CH Reply field is not 00, then, I2C-over-AUX Reply field must be 00 and be ignored. This fixes broken EDID reading when using an active DisplayPort to duallink DVI converter. If the AUX CH replier chooses to defer the transaction, a short read occurs and erroneous data is returned as the i2c reply due to a lack of length checking and failure to check for AUX ACK. As a result, broken EDIDs can look like: 0 1 2 3 4 5 6 7 8 9 a b c d e f 0123456789abcdef 00: bc bc bc ff bc bc bc ff bc bc bc ac bc bc bc 45 ???.???.???????E 10: bc bc bc 10 bc bc bc 34 bc bc bc ee bc bc bc 4c ???????4???????L 20: bc bc bc 50 bc bc bc 00 bc bc bc 40 bc bc bc 00 ???P???.???@???. 30: bc bc bc 01 bc bc bc 01 bc bc bc a0 bc bc bc 40 ???????????????@ 40: bc bc bc 00 bc bc bc 00 bc bc bc 00 bc bc bc 55 ???.???.???.???U 50: bc bc bc 35 bc bc bc 31 bc bc bc 20 bc bc bc fc ???5???1??? ???? 60: bc bc bc 4c bc bc bc 34 bc bc bc 46 bc bc bc 00 ???L???4???F???. 70: bc bc bc 38 bc bc bc 11 bc bc bc 20 bc bc bc 20 ???8??????? ??? 80: bc bc bc ff bc bc bc ff bc bc bc ff bc bc bc ff ???.???.???.???. ... which can lead to: [drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid, remainder [drm:drm_edid_block_valid] *ERROR* Raw EDID: <3>30 30 30 30 30 30 30 32 38 32 30 32 63 63 31 61 000000028202cc1a <3>28 00 02 8c 00 00 00 00 18 00 00 00 00 00 00 00 (............... <3>20 4c 61 73 74 20 62 65 61 63 6f 6e 3a 20 33 32 Last beacon: 32 <3>32 30 6d 73 20 61 67 6f 46 00 05 8c 00 00 00 00 20ms agoF....... <3>36 00 00 00 00 00 00 00 00 0c 57 69 2d 46 69 20 6.........Wi-Fi <3>52 6f 75 74 65 72 01 08 82 84 8b 96 24 30 48 6c Router......$0Hl <3>03 01 01 06 02 00 00 2a 01 00 2f 01 00 32 04 0c .......*../..2.. <3>12 18 60 dd 09 00 10 18 02 00 00 01 00 00 18 00 ..`.............

2010-12-14drm/radeon/kms: MC vram map needs to be >= pci aperture sizeAlex Deucher
commit b7d8cce5b558e0c0aa6898c9865356481598b46d upstream. The vram map in the radeon memory controller needs to be >= the pci aperture size. Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=28402 The problematic cards in the above bug have 64 MB of vram, but the pci aperture is 128 MB and the MC vram map was only 64 MB. This can lead to hangs.

Not upstream in Linus's tree as it was fixed by a much more intrusive patch in a different manner, commit c919b371cb734f42b11 2.6.35 and 2.6.36 do not contain blit support for evergreen asics so if they use unmappable vram, you can end up with an unreachable buffer address. This should not be applied to drm-next as that tree already contains evergreen blit support. This should only be applied to the 2.6.35 and 2.6.36 stable trees.

2010-10-28drm: Hold the mutex when dropping the last GEM reference (v2)Chris Wilson
commit 39b4d07aa3583ceefe73622841303a0a3e942ca1 upstream. In order to be fully threadsafe we need to check that the drm_gem_object refcount is still 0 after acquiring the mutex in order to call the free function. Otherwise, we may encounter scenarios like: Thread A: Thread B: drm_gem_close unreference_unlocked kref_put mutex_lock ... i915_gem_evict ... kref_get -> BUG ... i915_gem_unbind ... kref_put ... i915_gem_object_free ... mutex_unlock mutex_lock i915_gem_object_free -> BUG i915_gem_object_unbind kfree mutex_unlock Note that no driver is currently using the free_unlocked vfunc and it is scheduled for removal, hasten that process.

commit d270ae34eb77c58dea60e5b1e300a698d2ce39ac upstream. The IPS driver needs to know the current power consumption of the GMCH in order to make decisions about when to increase or decrease the CPU and/or GPU power envelope. So fix up the divisions to save the results so the numbers are actually correct (contrary to some earlier comments and code, these functions do not modify the first argument and use it for the result).

commit 6939a5aca7cfada279a24c307e772f33104fca20 upstream. The i915 driver has quite a few module unload bugs, the known ones at least have fixes that are targeting 2.6.37. However, in order to maintain a stable kernel, we should prevent this known random memory corruption following driver unload. This should have very low impact on normal users who are unlikely to need to unload the i915 driver.
