[PATCH 0/9] gma500: Fix SDVO DDC probing on Poulsbo
by Patrik Jakobsson 07 Dec '11

07 Dec '11

This set of patches removes psb_intel_output and replaces it with psb_intel_encoder and psb_intel_connector. It also replaces the SDVO code with a slightly modified version from i915. i915 SDVO needs Intel gmbus so this is added along with a SDVO DDC bus guessing fix for Poulsbo. Patrik Jakobsson (9): gma500: Initial support for our encoder and connector structs gma500: Remove psb_intel_output from ddc_probe and ddc_get_modes gma500: Fix encoder type checking for connectors gma500: … [View More]

Request for fixing atombios_get_encoder_mode
by Rafał Miłecki 07 Dec '11

07 Dec '11

In theory function atombios_get_encoder_mode should report ATOM_ENCODER_MODE_HDMI when TV supports audio. Current we report ATOM_ENCODER_MODE_DVI if card is DCE4. Is there any reason for it? Can we just drop that DCE4 condition? This fixme seems to be here since ever. -- Rafał ------------------------------------------------------------------------------ Cloud Services Checklist: Pricing and Packaging Optimization This white paper is intended to serve as a reference, checklist and point of … [View More]

[git pull] drm fixes the reduced version
by Dave Airlie 07 Dec '11

07 Dec '11

Hi Linus, Okay the 2 non-kexec fixes + one of the calloc changes as by looking at it, there was nothing stopping userspace for abusing the integer overflow on these ioctls. The other calloc changes either were kernel internal or had other things stopping userspace from exploiting them. Dave. The following changes since commit 45e713efe2fa574b6662e7fb63fae9497c5e03d4: Merge branch 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip (2011-12-05 16:54:15 -0800) … [View More]

Hi Linus, 3 fixes, one for an ongoing Intel VT-d/Ironlake GPU that I've been testing, and one kexec fix from Jerome for an issue reported on the list where the gpu writeback engines need to be switched off, along with a trivial fix from Alex. Due to the size of the kexec fix I've decided to keep this pull small. (I have some kzalloc->kcalloc fixes to check on). Dave.

[PATCH] drm/i915: fix infinite recursion on unbind due to ilk vt-d w/a
by Daniel Vetter 06 Dec '11

06 Dec '11

The recursion loop goes retire_requests->unbind->gpu_idle->retire_reqeusts. Every time we go through this we need a - active object that can be retired - and there are no other references to that object than the one from the active list, so that it gets unbound and freed immediately. Otherwise the recursion stops. So the recursion is only limited by the number of objects that fit these requirements sitting in the active list any time retire_request is called.
