|\ \ | | | | | | | | | | | | | | | | | | git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6 * 'sh/for-2.6.33' of git://git.kernel.org/pub/scm/linux/kernel/git/lethal/sh-2.6: sh64: fix tracing of signals.
| * | sh64: fix tracing of signals.Paul Mundt2010-02-15
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This follows the parisc change to ensure that tracehook_signal_handler() is aware of when we are single-stepping in order to ptrace_notify() appropriately. While this was implemented for 32-bit SH, sh64 neglected to make use of TIF_SINGLESTEP when it was folded in with the 32-bit code, resulting in ptrace_notify() never being called. As sh64 uses all of the other abstractions already, this simply plugs in the thread flag in the appropriate enable/disable paths and fixes up the tracehook notification accordingly. With this in place, sh64 is brought in line with what 32-bit is already doing. Reported-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Fix this issue by splitting the i915 suspend into a freeze part a suspend part, where the latter is not executed before creating a hibernation image, and the i915 resume into a "low-level" resume part and a thaw part, where the former is not executed after the image has been created.

At flip finish time, we need to unpin the old fb and decrement the flip pending count on the new buffer. The old code was conflating the two, and led to hangs when new direct rendered apps were started, replacing the existing frame buffer. This patch splits out the buffers and prevents the hangs.

So we can take advantage of any flushes posted whilst the buffer is active and pending processing by the GPU, by clearing its write_domain and updating its last_rendering_seqno -- thus saving a potential flush in deep queues and improves flushing behaviour upon eviction for both GTT space and fences. In order to reduce the time spent searching the active list for matching write_domains, we move those to a separate list whose elements are the buffers belong to the active/flushing list with pending writes. Orignal patch by Chris Wilson <chris@chris-wilson.co.uk>, forward-ported by me. In addition to better performance, this also fixes a real bug. Before this changes, i915_gem_evict_everything didn't work as advertised. When the gpu was actually busy and processing request, the flush and subsequent wait would not move active and dirty buffers to the inactive list, but just to the flushing list. Which triggered the BUG_ON at the end of this function. With the more tight dirty buffer tracking, all currently busy and dirty buffers get moved to the inactive list by one i915_gem_flush operation. I've left the BUG_ON I've used to prove this in there.

Test has also been made on LVDS panels with smaller size and CRT/HDMI/DP ports for different monitors on their all supported modes.

By changing the exit condition of this loop, we ensure that a minimum of one data block will always be returned. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

To reproduce the Oops which this fixes: 1) Create two "arrays" in the Array Configuratino Utility and several logical drives on each array. 2) cat /proc/driver/cciss/cciss* in an infinite loop 3) delete some of the logical drives in the first "array."
