2017-09-08meson: basic build system supportDaniel Vetter
Why? Because it's fast. Like really, really fast. Some data (from a snb laptop, so rather lower-powered): - Incremental build after $ touch lib/igt_core.c with meson: 0.6s It notices that the symbol list of the libigt.so hasn't changed and doesn't bother re-linking the almost 300 binaries we have. make -j 6 for the same scenario takes 44s. - Incremental build with nothing changed: make: 0.7s, meson: 0.2s This means stuff like --disable-git-hash is entirely pointless with meson, it's faster than a make ever can be (with 0.6s). - Reconfigure stage: ninja reconfigure 0.8s vs. ./configure 8.6s) - Running tests, after a full build: ninja test 6s vs. make check 24s - Full build (i.e. including ./autogen.sh respectively meson build), including tests, from a pristine git checkout. automake 2m49s vs. meson 44s.

2017-07-11igt: Add LOCAL defines for distro compatibilityArkadiusz Hiler
Each Linux distro takes a different spin on providing kernel's uapi headers (especialy the *drm*.h). You can get them with linux-headers, you can get them with libdrm. Sometime you can even get them twice, from both sources. Sometimes the headers match your kernel version, sometimes you end up stuck with headers matching the kernel that the given release of the distro came out with. This makes things harder for code that does not depend on libdrm, as we cannot have sane ./configure-time checks. So let's define LOCAL_ version for FENCE and EXECBUFFER2_WB defines until all the stable distros catch up (+/- some epsilon).

2017-06-08gem_wsim: Late balancing decision modeTvrtko Ursulin
An approximation of in kernel balancing where balancing decision is postponed to just before submitting the batch for execution. This is implemented by waiting on data dependencies in userspace before submitting each batch. Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
2017-06-08gem_wsim: Add static context balancerTvrtko Ursulin
This one assigns VCS engines for each created context in a round- robin fashion. By default each client starts the assignment from the first engine. In global mode the engines are assigned in the round-robin fashion between all the clients - which is identical to the i915 behaviour. Important difference is that doing it from gem_wsim means the assignment always start from a known point so the run-to-run behaviour is identical and repeatable, contrary to when i915 round- robin assignment is used.

2017-05-23gem_wsim: Add global balancing modeTvrtko Ursulin
In this mode ('-G' on the command line) all balancing operations are routed via the first client so the complete balancing state is shared. In other words the overall balancing behaviours is like there is only one client submitting the aggregate workload. This can help with the observed metrics and lead to better balancing decisions in a lot of cases. Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

2017-05-16gem_wsim: Add append workloadTvrtko Ursulin
Used with the '-a' command line switch which follows the same usage as '-w' and '-W', it enables to add append workload steps to the end of all normal workloads. This for example allows running any workload in the real-time mode: gem_wsim -w <some-workload> -a p.16667 Makes a workload to be run with the 60 Hz period. At the same time fix the periodic mode execution with dropped frames, or almost dropped frames. Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

2017-05-10wsim: Switch off heartbeat by defaultChris Wilson
For reasons I haven't completely fathomed, adding a heartbeat per frame is upsetting the qd-balancer when run with just a single client, e.g. ./gem_wsim -n 341724 -w wsim/media_mfe2_480p.wsim -c 1 -r 100 -b 1 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2017-05-10wsim: Limit the information updated during the heartbeatChris Wilson
The heartbeat should be sent after a period of idleness, it's sole purpose is to update our idea of the external load. As we are sending it currently in the middle of a busy period, we can reduce it to just bumping the queue-depth and reusing the most recent clocks, so that we do not perturb the RT timings greatly. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
2017-05-10wsim: Limit heartbeats to sync pointsChris Wilson
We only need a heartbeat if we don't have any inflight batches to those engine (the idea is to try and keep track of external usage). It only needs to be periodic, but use once a wait point for simplicity. Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
