The fence pin count should always be <= the bo pin count. If that's not the case then we have a funny problem and are leaking references somewhere. Which means we can catch fence pin leaks by checking for the same upper limit as we do for the bo pin count. Inspired by a discussion with Ville about a fence leak igt testcase. v2: Also check for fence->pin_count <= ggtt_vma->pin_count, since that might catch a leak even quicker. Also de-inline them, they're getting too big. v3: Don't separately check for MAX_PIN_COUNT since the > vma->pin_count check will catch that already (Chris).

For clients that submit large batch buffers the command parser has a substantial impact on performance. On my HSW ULT system performance drops as much as ~20% on some tests. Most of the time is spent in the command lookup code. Converting that from the current naive search to a hash table lookup reduces the performance drop to ~10%. The choice of value for I915_CMD_HASH_ORDER allows all commands currently used in the parser tables to hash to their own bucket (except for one collision on the render ring). The tradeoff is that it wastes memory. Because the opcodes for the commands in the tables are not particularly well distributed, reducing the order still leaves many buckets empty. The increased collisions don't seem to have a huge impact on the performance gain, but for now anyhow, the parser trades memory for performance. NB: Ville noticed that the error paths through the ring init code will leak memory. I've not addressed that here. We can do a follow up pass to handle all of the leaks. v2: improved comment describing selection of hash key mask (Damien) replace a BUG_ON() with an error return (Tvrtko, Ville) commit message improvements Signed-off-by: NBrad Volkin <bradley.d.volkin@intel.com> Reviewed-by: NDamien Lespiau <damien.lespiau@intel.com> Reviewed-by: NTvrtko Ursulin <tvrtko.ursulin@intel.com> Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>

It was always the intention to do the topdown allocation for context objects (Chris' idea originally). Unfortunately, I never managed to land the patch, but someone else did, so now we can use it. As a reminder, hardware contexts never need to be in the precious GTT aperture space - which is what is what happens with the normal bottom up allocation we do today. Doing a top down allocation increases the odds that the HW contexts can get out of the way, especially with per FD contexts as is done in full PPGTT Signed-off-by: NBen Widawsky <ben@bwidawsk.net> Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>

Add runtime PM support for VLV, but leave it disabled. The next patch enables it. The suspend/resume sequence used is based on [1] and [2]. In practice we depend on the GT RC6 mechanism to save the HW context depending on the render and media power wells. By the time we run the runtime suspend callback the display side is also off and the HW context for that is managed by the display power domain framework. Besides the above there are Gunit registers that depend on a system-wide power well. This power well goes off once the device enters any of the S0i[R123] states. To handle this scenario, save/restore these Gunit registers. Note that this is not the complete register set dictated by [2], to remove some overhead, registers that are known not to be used are ignored. Also some registers are fully setup by initialization functions called during resume, these are not saved either. The list of registers can be further reduced, see the TODO note in the code.
