This patchset is a Xen port of Marc's patchset.
arm64: KVM: Mediate access to GICv3 sysregs at EL2 [1]
The current RFC patchset is a subset of [1], as it handleing only
Group1 traps
as a PoC. Most of the trap code is added in vsysreg.c. Trap handler
function is kept
independent of the usual guest trap handling code.
Looking for feedback on this approach.
This cover letter does not seem to match the series. Please update
it on every time you send a series.
%s/vsysreg.c/vgic-v3-sr..
Could you please review the other patches in the series, so that I
can send v2.
Here the major comments for the series (included patch not reviewed):
1) You seem to miss some patches from Linux. I would like to
understand why they are not there.
if code is ported to xen, it is perfectly fine to take only relevant
patches.
For instance we are not providing any command line option to
individually enable group1 grou0 traps.
2) Strangely some commits does not match the Linux one either in
order and content (I am not speaking about the changes required by
Xen). For instance this is the case of patch #14 "arm64: vgic-v3: Add
ICV_AP(0/1)Rn_EL1 handler". If you port commit from Linux, then you
should follow the same. This help a lot for review.
Since we are not doing individually enable of group0/1, it doesnt make
sense to have two set of patches for ICV_AP0 / ICV_AP1. So I merged it.
3)
Code organization:
1) Please drop __ from all functions
ok I will change.
2) All functions not exported *should* be static. At the same time
you need to make sure that the series are bisectable. So you probably
hook the file in the build system at the end rather than in #3.
ok.
Cheers,
