Robert Bragg [Thu, 27 Oct 2016 21:08:19 +0000 (22:08 +0100)]
i965: Allow a per gen timebase scale factor

Prior to Skylake the Gen HW timestamps were driven by a 12.5MHz clock
with the convenient property of being able to scale by an integer (80)
to nanosecond units.

For Skylake the frequency is 12MHz or a scale factor of 83.333333

This updates gen_device_info to track a floating point timebase_scale
factor and makes corresponding _queryobj.c changes to no longer assume a
scale factor of 80 works across all gens.

Although the gen6_ code could have been been left alone, the changes
keep the code more comparable, and it now shares a few utility functions
for scaling raw timestamps and calculating deltas. The utility for
calculating deltas takes into account 32 or 36bit overflow depending on
the current kernel version.

Note: this leaves the timestamp handling of ARB_query_buffer_object
untouched, which continues to use an incorrect scale of 80 on Skylake
for now. This is more awkward to solve since the scaling is currently
done using a very limited uint64 ALU available to the command parser
that doesn't support multiply or divide where it's already taking a
large number of instructions just to effectively multiple by 80.

This fixes piglit arb_timer_query-timestamp-get on Skylake

v2: (Ken) Update timebase_scale for platforms past Skylake/Broxton too.

anv: handle failures when growing reloc lists

Growing the reloc list happens through calling anv_reloc_list_add() or

that check the result and set the batch error status if needed.

v2:

    the error, for that, keep track of the errors in the batch instead (Jason).
  - Make reloc list growth go through helpers so we can have a central
    place where we can do error tracking (Jason).

v3:
  - Callers that need the offset returned by anv_reloc_list_add() can

v4:
  - Let anv_batch_emit_reloc() return an uint64_t as it originally did,
    there is no real benefit in having it return a VkResult.
  - Do not add an is_aux parameter to add_surface_state_reloc(), instead

Most of the time we use macros that handle this situation transparently,
but there are some cases were we need to handle this explicitly.

This patch makes sure we don't crash, notice that error handling takes
place in the function that actually failed the allocation,
anv_batch_emit_dwords(), which will set the status field of the batch
so it can be used at a later moment to report the error to the user.

v2:
  - Not crashing is not good enough, we need to keep track of the error
    (Topi, Jason). Iago: now that we track errors in the batch, this
    is being handled.

anv/cmd_buffer: add a status field to anv_batch

The vkCmd*() functions do not report errors, instead, any errors should be
reported by the time we call vkEndCommandBuffer(). This means that we
need to make the driver robust against incosistent and/or imcomplete
command  buffer states through the command recording process, particularly,
avoid crashes due to access to memory that we failed to allocate previously.

The strategy used to do this is to track the first error ocurred while
recording a command buffer in the batch associated with it. We use the
batch to track this information because the command buffer may not be
visible to all parts of the driver that can produce errors we need to be
aware of (such as allocation failures during batch emissions).

Later patches will use this error information to guard parts of the driver
that may not be safe to execute.

v2: Move the field from the command buffer to the batch so we can track
    errors from batch emissions (Jason)

v3: Registering errors in the command buffer's batch during
    anv_create_cmd_buffer() is unnecessary, since the command buffer
    is freed at the end of the function in that case (Topi)
