[PATCH 00/24] PPGTT dynamic page allocations

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This new version tries to remove as many unnecessary changes as possible from
the previous RFC.
 
For GEN8, it has also been extended to work in logical ring submission (lrc)
mode, as it will be the preferred mode of operation.
I also tried to update the lrc code at the same time the ppgtt refactoring
occurred, leaving only one patch that is exclusively for lrc.

This list can be seen in 3 parts:
[01-10] Include code rework for PPGTT (all GENs).
[11-14] Adds page table allocation for GEN6/GEN7
[15-24] Enables dynamic allocation in GEN8. It is enabled for both legacy
and execlist submission modes.
