* oprofile/x86: fix msr access to reserved countersRobert Richter2010-02-261-5/+4
| | | | | | | | | During switching virtual counters there is access to perfctr msrs. If the counter is not available this fails due to an invalid address. This patch fixes this. Cc: stable@kernel.org Signed-off-by: Robert Richter <robert.richter@amd.com>

* oprofile/x86: fix perfctr nmi reservation for mulitplexingRobert Richter2010-02-262-24/+6
| | | | | | | | | | Multiple virtual counters share one physical counter. The reservation of virtual counters fails due to duplicate allocation of the same counter. The counters are already reserved. Thus, virtual counter reservation may removed at all. This also makes the code easier. Cc: stable@kernel.org Signed-off-by: Robert Richter <robert.richter@amd.com>
* oprofile/x86: add comment to counter-in-use warningNaga Chumbalkar2010-02-261-0/+9
| | | | | | | | | | | | | | | | | | | | | Currently, oprofile fails silently on platforms where a non-OS entity such as the system firmware "enables" and uses a performance counter. There is a warning in the code for this case. The warning indicates an already running counter. If oprofile doesn't collect data, then try using a different performance counter on your platform to monitor the desired event. Delete the counter from the desired event by editing the /usr/share/oprofile/<cpu_type>/<cpu>/events file. If the event cannot be monitored by any other counter, contact your hardware or BIOS vendor.

* oprofile/x86: implement randomization for IBS periodic op counterRobert Richter2010-02-261-6/+63
| | | | | | | | | | | | | | | | | | | | | | IBS selects an op (execution operation) for sampling by counting either cycles or dispatched ops. Better statistical samples can be produced by adding a software generated random offset to the periodic op counter value with each sample. This patch adds software randomization to the IBS periodic op counter. The lower 12 bits of the 20 bit counter are randomized. IbsOpCurCnt is initialized with a 12 bit random value. There is a work around if the hw can not write to IbsOpCurCnt. Then the lower 8 bits of the 16 bit IbsOpMaxCnt [15:0] value are randomized in the range of -128 to +127 by adding/subtracting an offset to the maximum count (IbsOpMaxCnt). The linear feedback shift register (LFSR) algorithm is used for pseudo-random number generation to have low impact to the memory system. Signed-off-by: Robert Richter <robert.richter@amd.com>
* oprofile/x86: implement lsfr pseudo-random number generator for IBSSuravee Suthikulpanit2010-02-261-0/+23
| | | | | | | | | | | | | | | | | | | This patch implements a linear feedback shift register (LFSR) for pseudo-random number generation for IBS. For IBS measurements it would be good to minimize memory traffic in the interrupt handler since every access pollutes the data caches. Computing a maximal period LFSR just needs shifts and ORs. The LFSR method is good enough to randomize the ops at low overhead. 16 pseudo-random bits are enough for the implementation and it doesn't matter that the pattern repeats with a fairly short cycle. It only needs to break up (hard) periodic sampling behavior. The logic was designed by Paul Drongowski.

* oprofile/x86: implement IBS cpuid feature detectionRobert Richter2010-02-261-17/+63
| | | | | | | | | | | | | | | | | | | | This patch adds IBS feature detection using cpuid flags. An IBS capability mask is introduced to test for certain IBS features. The bit mask is the same as for IBS cpuid feature flags (Fn8000_001B_EAX), but bit 0 is used to indicate the existence of IBS. The patch also changes the handling of the IbsOpCntCtl bit (periodic op counter count control). The oprofilefs file for this feature (ibs_op/dispatched_ops) will be only exposed if the feature is available, also the default for the bit is set to count clock cycles. In general, the userland can detect the availability of a feature by checking for the corresponding file in oprofilefs. If it exists, the feature also exists. This may lead to a dynamic file layout depending on the cpu type with that the userland has to deal with. Current opcontrol is compatible. Signed-off-by: Robert Richter <robert.richter@amd.com>
* oprofile/x86: remove node check in AMD IBS initializationRobert Richter2010-02-261-10/+0
| | | | | | | | | | | | Standard AMD systems have the same number of nodes as there are northbridge devices. However, there may kernel configurations (especially for 32 bit) or system setups exist, where the node number is different or it can not be detected properly. Thus the check is not reliable and may fail though IBS setup was fine. For this reason it is better to remove the check.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a new page flip is requested, we need to both queue an unpin for the current framebuffer, and also increment the flip pending count on the newly submitted buffer. 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.

This is normally handled by intel_pin_and_fence_fb_obj(), but the intelfb_create() likes to be different and do the pinning itself. However, it aligns the buffer object incorrectly for pre-i965 chipsets causing a PGTBL_ERR when it is installed onto the output.

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.

This patch maps it to the error EREMOTEIO, which is exported to userland through errno.h. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> Cc: stable@kernel.org
