Ring saving patches round 3
by Christian König 17 Jul '12

17 Jul '12

I hope that this is the last round necessary, beside including all the comments from Michel and Jerome there is a small change to patch 15 to not save anything if the all fences on a ring are already signaled. The branch is also available as: git://people.freedesktop.org/~deathsimple/linux next Cheers, Christian.

[PATCH] drm/radeon: fix VM page table setup on SI
by alexdeucher＠gmail.com 17 Jul '12

17 Jul '12

From: Alex Deucher <alexander.deucher(a)amd.com> 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.

radeon si: si_mc_load_microcode, blackout code path never used
by Sylvain BERTRAND 17 Jul '12

The code path in that function makes the "blackout thingy" never used: ... if (running == 0) { if (running) { ...blackout thingy... } ... Is this normal behavior? -- Sylvain
