2010-08-02drm/radeon: fall back to GTT if bo creation/validation in VRAM fails.Michel Dänzer1-9/+18
This fixes a problem where on low VRAM cards we'd run out of space for validation. [airlied: Tested on my M7, Thinkpad T42, compiz works with no problems.] Signed-off-by: Michel Dänzer <daenzer@vmware.com> Cc: stable@kernel.org Signed-off-by: Dave Airlie <airlied@redhat.com>

This is required for the NB_MISC regs on rs780/rs880 which means HDMI/DVI/DP ports using PCIEPHY won't work without it. It might also help with s/r (asic init) issues on other atombios cards.

2010-07-07drm: correctly update connector DPMS status in drm_fb_helperJesse Barnes1-3/+20
We don't currently update the DPMS status of the connector (both in the connector itself and the connector's DPMS property) in the fb helper code. This means that if the kernel FB core has blanked the screen, sysfs will still show a DPMS status of "on". It also means that when X starts, it will try to light up the connectors, but the drm_crtc_helper code will ignore the DPMS change since according to the connector, the DPMS status is already on. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=28436 (the annoying "my screen was blanked when I started X and now it won't light up" bug).

2010-07-07drm: implement helper functions for scanning lru listDaniel Vetter2-5/+177
These helper functions can be used to efficiently scan lru list for eviction. Eviction becomes a three stage process: 1. Scanning through the lru list until a suitable hole has been found. 2. Scan backwards to restore drm_mm consistency and find out which objects fall into the hole. 3. Evict the objects that fall into the hole. These helper functions don't allocate any memory (at the price of not allowing any other concurrent operations). Hence this can also be used for ttm (which does lru scanning under a spinlock). Evicting objects in this fashion should be more fair than the current approach by i915 (scan the lru for a object large enough to contain the new object). It's also more efficient than the current approach used by ttm (uncoditionally evict objects from the lru until there's enough free space).

2010-07-07drm/ttm: Allocate the page pool manager in the heap.Francisco Jerez2-39/+33
Repeated ttm_page_alloc_init/fini fails noisily because the pool manager kobj isn't zeroed out between uses (we could do just that but statically allocated kobjects are generally considered a bad thing). Move it to kzalloc'ed memory. Note that this patch drops the refcounting behavior of the pool allocator init/fini functions: it would have led to a race condition in its current form, and anyway it was never exploited.

2010-07-05ARM: 6205/1: perf: ensure counter delta is treated as unsignedWill Deacon1-1/+1
Hardware performance counters on ARM are 32-bits wide but atomic64_t variables are used to represent counter data in the hw_perf_event structure. The armpmu_event_update function right-shifts a signed 64-bit delta variable and adds the result to the event count. This can lead to shifting in sign-bits if the MSB of the 32-bit counter value is set. This results in perf output such as: Performance counter stats for 'sleep 20': 18446744073460670464 cycles <-- 0xFFFFFFFFF12A6000 7783773 instructions # 0.000 IPC 465 context-switches 161 page-faults 1172393 branches 20.154242147 seconds time elapsed This patch ensures that the delta value is treated as unsigned so that the right shift sets the upper bits to zero.

2010-07-02drm/i915: change default panel fitting mode to preserve aspect ratioJesse Barnes1-2/+2
We did this a long time ago in the DDX driver, but now this fix belongs in the kernel. Preserving the aspect ratio is a nicer default. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=18033.

2010-07-02drm/i915: take struct_mutex in i915_dma_cleanup()Dan Carpenter1-0/+2
intel_cleanup_ring_buffer() calls drm_gem_object_unreference() (as opposed to drm_gem_object_unreference_unlocked()) so it needs to be called with "struct_mutex" held. If we don't hold the lock, it triggers a BUG_ON(!mutex_is_locked(&dev->struct_mutex)); I also audited the other places that call intel_cleanup_ring_buffer() and they all hold the lock so they're OK. This was introduced in: 8187a2b70e3 "drm/i915: introduce intel_ring_buffer structure (V2)" and it's a regression from v2.6.34.

2010-07-02drm/i915: Fix CRT hotplug regression in 2.6.35-rc1Andy Lutomirski3-8/+11
Commit 7a772c492fcfffae812ffca78a628e76fa57fe58 has two bugs which made the hotplug problems on my laptop worse instead of better. First, it did not, in fact, disable the CRT plug interrupt -- it disabled all the other hotplug interrupts. It seems rather doubtful that that bit of the patch fixed anything, so let's just remove it. (If you want to add it back, you probably meant ~CRT_HOTPLUG_INT_EN.) Second, on at least my GM45, setting CRT_HOTPLUG_ACTIVATION_PERIOD_64 and CRT_HOTPLUG_VOLTAGE_COMPARE_50 (when they were previously unset) causes a hotplug interrupt about three seconds later. The old code never restored PORT_HOTPLUG_EN so this could only happen once, but they new code restores those registers. So just set those bits when we set up the interrupt in the first place.
