Subject: [PATCH 0/9] xen/arm: Simplify do_trap_*_abort_guest
Date: Wed, 22 Jun 2016 14:21:00 +0100 [thread overview]
Message-ID: <1466601669-25398-1-git-send-email-julien.grall@arm.com> (raw)
Hello all,
The current data/instruction abort paths contain unnecessary code and
translate to often a VA to a IPA. This series aim to simplify this path.
Now that the register HPFAR_EL2 is read in case which can be affected
by the erratum 834220 on Cortex-A57, we need to implement a workaround
for it (see patch #9). This patch replaces the documentation one [1] in
the patch series that is part of "xen/arm: Introduce alternative runtime
paching for ARM64" [2].
This series is based on version 4 of "xen/arm: Introduce alternative runtime
patching for ARM64" [3]. A branch with the two series can be found on xenbits:
git://xenbits.xen.org/people/julieng/xen-unstable.git branch abort-handlers-v1
Yours sincerely,
