[PATCH v3 00/25] PPGTT dynamic page allocations

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

 



This new patchset addresses most of the comments from v2. It still teardowns
pagetables (which I plan to ammend shortly), but I think there were already
enough changes to justify it.

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:
[01-09] Include code rework for PPGTT (all GENs).
[10-15] Adds page table allocation for GEN6/GEN7
[16-25] Enables dynamic allocation in GEN8,for both legacy and
execlist submission modes.
