2016-07-25intel_chipset: Fixup HAS_PCH_SPLIT() to exclude AtomsChris Wilson
The Atoms do not have the PCH split, exclude them from HAS_PCH_SPLIT(). At the time, I was planning to add the feature flag and make intel_pch_type() useful, but for now take the simple option of expanding th predicate. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2016-06-30intel_chipset: Replace lookup of GT size with computationChris Wilson
Instead of a large if-chain for matching devid to GT, we can just compute it directly from the encoded devid. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2016-06-30lib: Start weaning off defunct intel_chipset.hChris Wilson
Several years ago we made the plan of only having one canonical source for i915_pciids.h, the kernel and everyone importing their definitions from that. For consistency, we style the intel_device_info after the kernel, most notably using a generation mask and a per-codename bitfield. This first step converts looking up the generation for a devid tree from a massive if(devid)-chain to a (cached) table lookup. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>

2016-05-12tools/intel_bios_reader: add --all-panels option to dump all panelsJani Nikula
Only dump the one matching panel_type by default. Cleans up the output, and allows the users to get more verbose output if he so chooses. Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2016-05-12tools/intel_bios_reader: add support for dumping only specific sectionJani Nikula
Now that the parsers for blocks don't depend on the dump ordering, we can also choose to dump specific sections only. Signed-off-by: Jani Nikula <jani.nikula@intel.com>

2016-05-12tools/intel_bios_reader: dump the blocks in numerical orderJani Nikula
All parsers fetch the information they need without ordering constraints, so dump all in numerical order. This also makes it unnecessary to track already dumped blocks. Signed-off-by: Jani Nikula <jani.nikula@intel.com>
2016-05-12tools/intel_bios_reader: let the user specify panel type on the command lineJani Nikula
On some systems the VBT panel type may be overridden in the opregion, and we can't necessarily get at that. Let the user specify it on the command line. As a byproduct, the section parsing order no longer matters. Signed-off-by: Jani Nikula <jani.nikula@intel.com>

Unlike in the kernel driver coding style, IS_965() matches the platform and all subsequent ones. Replace IS_965() with suitable but less confusing alternatives. Most occurences are on code paths that only get called for gens 2, 3 and 4, so replace those with IS_GEN4(). In the one other call site just flip the condition to check for gens 2 and 3 instead.

2016-03-24lib: Add a GPU error detectorChris Wilson
If we listen to the uevents from the kernel, we can detect when the GPU hangs. This requires us to fork a helper process to do so and send a signal back to the parent. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-03-19lib/igt_aux: Divert ioctls for signal injectionChris Wilson
To simplify and speed up running interruptible tests, use a custom ioctl() function that control the signaling and detect when we need no more iterations to trigger an interruption. We use a realtime timer to inject the signal after a certain delay, increasing the delay on every loop to try and exercise different code paths within the function. The first delay is very short such that we hopefully enter the kernel with a pending signal. Clients should use struct igt_sigiter iter = {}; while (igt_sigiter_repeat(&iter, enable_interrupts=true)) do_test() to automatically repeat the test until we can inject no more signals into the ioctls. This is condensed into a macro igt_interruptible(enable_interrupts=true) do_test(); for convenience. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2016-03-03tests: fix CRTC assignment for a few testsPaulo Zanoni
All the tests I wrote always assumed that every connector supported CRTC 0. This is not the case for BSW and possibly others, so fix the tests before the CI reports more failures. Signed-off-by: Paulo Zanoni <paulo.r.zanoni@intel.com>

2016-02-13aubdump: Don't use .so constructors for initializingKristian Høgsberg Kristensen
This doesn't seem to work when mixed with constructors in other shared objects or other creative uses of the linker. Let's stick with a simpler mechanism, where we look up the libc functions when our hooks are called for the first time.

2016-01-29tools/intel_residency: use setitimer instead of {,u}alarmPaulo Zanoni
It seems that Android doesn't have ualarm(). Let's use setitimer() instead. The tool still won't compile on Android due to igt_fb requiring Cairo, but we're supposed to solve this in another patch since our igt_fb calls don't actually require Cairo.

2016-01-25tools: add intel_residencyPaulo Zanoni
After the recent discussions regarding the effects of the vblank disabling policies on PC state residencies, I started running some experiments to reevaluate some non-intuitive conclusions I had reached. In order to help me do this, I decided to write this tool. The idea is very simple: the tool puts the system on an screen-on idle state, checks which PC state residency is the deepest we can reach, measures its residency, then does some not-so-idle tests and measures the residencies. You can use the tool to compare different Kernel trees and you can also use the tool to compare enabled vs disabled features. It's obvious that these cases do not represent real-world use cases of our driver, but they are already enough to highlight differences between the many patches I wrote. I was even able to catch a bug in one of my patches by spotting an unexpected regression in the residencies. I've been using this tool for FBC, but I expect it to also be useful for PSR, DRRS and similar features. I've been measuring the effects of different optimizations I wrote, and I've also been measuring the FBC vs no-FBC cases. It is also important to highlight that if your system is not properly configured for efficient power savings the tool may not be able to show differences between the results. On my Broadwell machine, for example, if I don't run "powertop --auto-tune" before running the tool, I get PC2 as the deepest state, and 90%+ residency for every workload. After properly configuring the machine, I get PC7 as the deepest state, which is the expected. So far I only tested this tool on BDW and SKL, and it may hit some unexpected assertions for older platforms. I only implemented the cases that are immediately useful for me, but we may also expand the tool in the future. We can add more important workloads. We can add support for screen-off cases, so we can compare the effects of runtime PM and other screen-off features. There's a lot we can do, but none of this is on my current priority list. And remember: /usr/bin/paste is your friend when comparing results. v2: - Be more idle at setup_idle(). - Improve printing for /usr/bin/paste usage.

Similar to what's done in kernel.
