[RFC][PATCH 0/3] ARMv8.4-TTST extension

Posted by Rémi Denis-Courmont 4 years, 11 months ago

	Hello,

The following changes since commit 6d3fd902ab9c4d6762532d4b5cce2275e458aa32:

  target/arm: refactor vae1_tlbmask() (2020-12-18 12:27:56 +0200)

follow. They add support for small translation tables, allowing for 
translation regimes as small as 16-bits. This extension is nominally a 
required dependency of Secure EL2.

----------------------------------------------------------------
Rémi Denis-Courmont (3):
      target/arm: keep translation start level unsigned
      target/arm: ARMv8.4-TTST extension
      target/arm: enable Small Translation tables in max CPU
