Subject: [PATCHv4 00/10] CONFIG_DEBUG_VIRTUAL for arm64
Date: Tue, 29 Nov 2016 10:55:19 -0800 [thread overview]
Message-ID: <1480445729-27130-1-git-send-email-labbott@redhat.com> (raw)
Hi,
This is v4 of the series to add CONFIG_DEBUG_VIRTUAL for arm64. This mostly
expanded on __pa_symbol conversion with a few new sites found. There's also
some reworking done to avoid calling __va too early. __va relies on having
memstart_addr set so very early code in early_fixmap_init and early KASAN
initialization can't just call __va(__Ipa_symbol(...)) to get the linear map
alias. I found this while testing with DEBUG_VM.
All of this could use probably use more testing under more configurations.
KVM, Xen, kexec, hibernate should all be tested.
Thanks,
Laura
