[RFC PATCH v5 2/5] target/riscv: rvv: Provide a fast path using direct access to host ram for unmasked unit-stride load/store |
|
Date: |
Wed, 17 Jul 2024 21:39:33 +0800 |
This commit references the sve_ldN_r/sve_stN_r helper functions in ARM
target to optimize the vector unmasked unit-stride load/store
implementation with following optimizations:
* Get the page boundary
* Probing pages/resolving host memory address at the beginning if
possible
* Provide new interface to direct access host memory
* Switch to the original slow TLB access when cross page element/violate
page permission/violate pmp/watchpoints in page
The original element load/store interface is replaced by the new element
load/store functions with _tlb & _host postfix that means doing the
element load/store through the original softmmu flow and the direct
access host memory flow.
