The "error" variable is unsigned so it's never less than zero. I changed it to check if (freq < current_freq) directly. "best_error" is also unsigned so "best_error - 100" could be a large number instead of a negative. Since "error" is unsigned it is never less than a negative and so the cases where "best_error" is less than or equal to 100 are false. Signed-off-by:

On systems using kexec, the new kernel is booted straight from the old kernel, without any warning to the graphics driver. So the GPU is basically left as-is in a running state, however the CPU side is completly reset. Without stating the saneness of anyone using kexec on live systems, we should at least try not to crash the GPU. This patch resets 3 registers to 0 that could cause bad things to happen to the running system. This allows kexec to work on a Power6/RN50 system. Signed-off-by: -

rv6xx/rv7xx/evergreen families supported; older asics did not have an internal thermal sensor. Note, not all oems use the internal thermal sensor, so it's only exposed in cases where it is used. Note also, that most laptops use an oem specific ACPI solution for GPU thermal information rather than using the internal thermal sensor directly. v2: export millidegrees celsius, use hwmon device properly. v3: fix Kconfig Signed-off-by:

There's no convenient/reliable way for drivers to both obey the dithering mode property, and to be able to attempt to provide a good default in all cases. This commit adds an "auto" method to the property which drivers can default to if they wish, whilst still allowing the user to override the choice as they do now. Signed-off-by:

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). Signed-off-by:

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). Signed-Off-by:

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. This fixes a regression with reloading kms modules at runtime, since page allocator was introduced. Signed-off-by:
