2011-09-09tests: basic ring<->cpu and ring<->ring testsfor-benDaniel Vetter4-0/+296
Using a dummy reloc that doesn't matter to trick the kernel into synchroizing the rings. v2: properly apply MI_NOOP workaround to MI_FLUSH_DW and switch to MI_COND_BATCH_BUFFER_END as a dummy command on the render ring to avoid PIPE_CONTROL errata. v3: somebody clever decided that in C, you cound from 1, i.e. I915_EXEC_RENDER == 1. It works now ... Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2011-09-09test/gem_storedw_*: tune some moreDaniel Vetter2-5/+5
MI_*/PIPE_CONTROL writes need to be in DOMAIN_INSTRUCTION, because that is what mesa uses and I plan to use this to work around a gen6 ppgtt issue. Also testing with intentionally b0rked GFX_MODE on my snb shows that we need to increase the loop counter a bit to reliably hit the tlb invalidation problem. Test still completes within a few seconds. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>

2011-09-05intel_gpu_top: access hardware before running profiling commandEugeni Dodonov1-5/+5
Without this patch, intel_gpu_top will try to get access to the hardware after running the profiling command in the background. In case such access fails, the main process quits, but the background one will continue running. So let's move this test up, so it is done before we fork.

This patch fixes adopts the code to the kernel coding_style.
2011-09-05intel_gpu_top: support profiling user-specified commandsEugeni Dodonov2-1/+65
This patch adds support for running intel_gpu_top to profile specific commands. The required command will be carried out in separate process, and main intel_gpu_top will leave when the child process will exit. Signed-off-by: Eugeni Dodonov <eugeni.dodonov@intel.com>
2011-09-05intel_gpu_top: support non-interactive modeEugeni Dodonov2-41/+112
This patch adds support for non-interactive mode, invoked by running with '-o output' switch. In this case, no interactive output is being performed, but the execution statistics are being saved into the output file. The output file is generated in both human and gnuplot-readable format. Unlike interactive mode, where non-supported pipes and non-active registers are skipped, the content of such pipes and registers is recorded into the log file to simplify parsing and standardize the list of columns. Also, unlike interactive mode, the registers are not sorted according to the usage - this way, their variation over time can be analysed offline.

2011-09-05intel_gpu_top: suport command line parameters and variable samples perEugeni Dodonov2-4/+55
second This patch adds support for getopt, and adds two default parameters to it: -h to show usage notes; and -s to allow user to define number of samples to acquire per second. Manpage documentation is also adjusted accordingly. Signed-off-by: Eugeni Dodonov <eugeni.dodonov@intel.com>
2011-09-05intel_gpu_top: account for time spent in syscallsEugeni Dodonov1-12/+41
This allows intel_gpu_top to properly account for time spent inside system calls. Effectively, with previous implementation, intel_gpu_top could spent longer than 1s between consecutive measures. This attempts to minimize the extra time spent while polling for data. Signed-off-by: Eugeni Dodonov <eugeni.dodonov@intel.com>
2011-08-12tests: add store dword testsJesse Barnes3-0/+284
Add a couple of simple store dword tests to test memory coherence. gem_storedw_loop simply executes a batch that continually stores an incremented value to a target buffer object, checking the results after each batch completes. gem_storedw_batches_loop does the same thing, but creates a new command batch buffer for each iteration, which can exercise the buffer creation code. This test is based on one from Andrzej Kacprowski from Intel. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org>

2011-07-28intel-gpu-tools/debugging: shader debuggerBen Widawsky11-1/+1463
high level summary of the files: * debug_rdata - get current state from debug registers. Helpful when developing the debugger, and could serve some purpose in the future. * eudb - the debugger itself * eviction_macro - generate the proper macro to flush the EU render cache until I get control flow working * pre_cpp - an evaluating c preprocesser like thing, to be used before cpp * sr - the system routine, exception handler which runs on the EU * test - a very basic test system routine * debug.h

2011-07-28intel-gpu-tools/forcewaked: sample forcewake appBen Widawsky2-0/+107
This app is required for debug features which seem to (undocumented) reset themselves if/when the GT goes to sleep. It is also useful for those doing general debugging or profiling from userspace when they do not wish to have the GT sleep. v2: made forcewaked more daemon-like Cc: Chris Wilson <chris@chris-wilson.co.uk>

2011-07-02gem_stress: Add an option to test handling of signalsChris Wilson2-0/+41
As signals cause the syscalls to be interrupted, we often need to clean up partial state before returning to userspace. Often a source of unamusing bugs, so encourage gem_stress to provoke them. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
