[Qemu-devel] [PATCH v2 0/9] target-arm: EL3 trap support |
Date: |
Wed, 22 Apr 2015 12:09:12 -0500 |
Initial patchset adding support for trapping to an EL other than EL1. Support
includes changes to interfaces to allow specification of the target EL. Also
includes the addition of the ARMv8 CPTR system registers used for controlling
the trapping of features.
---
v1 -> v2
- Removed use of MAX through out the patch when setting target_el
- Updated FP trap support to pass a target exception EL rather than just an
enable boolean.
- Added utility functions for determining the target exception EL
- Broke up cptr and cpacr access functions
- Added HCPTR CP register entry and HCPTR/CPTR_EL2 zero entries
- Broke out TCR changes into their own patch and added support for handling the
lack of TTBR1
- Simplified wfx checking
- General comment cleanup
Greg Bellows (9):
target-arm: Add exception target el infrastructure
target-arm: Extend helpers to route exceptions
target-arm: Update interrupt handling to use target EL
target-arm: Add AArch64 CPTR registers
target-arm: Extend FP checks to use an EL
target-arm: Add TTBR regime function and use
target-arm: Add EL3 and EL2 TCR checking
target-arm: Add WFx syndrome function
target-arm: Add WFx instruction trap support
