Refactor pinning and unpinning of contexts, such that the default context for an engine is pinned during initialisation and unpinned during teardown (pinning of the context handles the reference counting). Thus we can eliminate the special case handling of the default context that was required to mask that it was not being pinned normally. v2: Rebalance context_queue after rebasing. v3: Rebase to -nightly (not 40 patches in) v4: Rebase onto request_alloc unwinding Signed-off-by: NChris Wilson <chris@chris-wilson.co.uk> Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Reviewed-by: NTvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Reviewed-by: NMika Kuoppala <mika.kuoppala@intel.com> Link: http://patchwork.freedesktop.org/patch/msgid/1461833819-3991-19-git-send-email-chris@chris-wilson.co.uk

In the next patches, we want to move the work out of freeing the request and into its retirement (so that we can free the request without requiring the struct_mutex). This means that we cannot rely on unreferencing the request to completely teardown the request any more and so we need to manually unwind the failed allocation. In doing so, we reorder the allocation in order to make the unwind simple (and ensure that we don't try to unwind a partial request that may have modified global state) and so we end up pushing the initial preallocation down into the engine request initialisation functions where we have the requisite control over the state of the request. Moving the initial preallocation into the engine is less than ideal: it moves logic to handle a specific problem with request handling out of the common code. On the other hand, it does allow those backends significantly more flexibility in performing its allocations.

The code to switch_mm() is already handled by i915_switch_context(), the only difference required to setup the aliasing ppgtt is that we need to emit te switch_mm() on the first context, i.e. when transitioning from engine->last_context == NULL. This allows us to defer the initialisation of the GPU from early device initialisation to first use, which should marginally speed up both. The caveat is that we then defer the context initialisation until first use - i.e. we cannot assume that the GPU engines are initialised. For example, this means that power contexts for rc6 (Ironlake) need to explicitly loaded, as they are.

I just noticed that VLV/CHV have a RAWCLK_FREQ register just like PCH platforms. It lives in the display power well, so we should update it when enabling the power well. Interestingly the BIOS seems to leave it at the reset value (125) which doesn't match the rawclk frequency on VLV/CHV (200 MHz). As always with these register, the spec is extremely vague what the register does. All it says is: "This is used to generate a divided down clock for miscellaneous timers in display." Based on a quick test, at least AUX and PWM appear to be unaffected by this. But since the register is there, let's configure it in accordance with the spec. Note that we have to move intel_update_rawclk() to occur before we touch the power wells, so that the dev_priv->rawclk_freq is already populated when the disp2 enable hook gets called for the first time. I think this should be safe to do on other platforms as well.
