Subject: [Bug gdb/29421] New: Extend aarch64 pauth xml for gdbstub and kernel mode
Date: Wed, 27 Jul 2022 19:10:42 +0000 [thread overview]
Message-ID: <bug-29421-4717@http.sourceware.org/bugzilla/> (raw)
https://sourceware.org/bugzilla/show_bug.cgi?id=29421
Bug ID: 29421
Summary: Extend aarch64 pauth xml for gdbstub and kernel mode
Product: gdb
Version: HEAD
Status: NEW
Severity: enhancement
Priority: P2
Component: gdb
Assignee: unassigned at sourceware dot org
Reporter: rth at gcc dot gnu.org
Target Milestone: ---
The current definition of org.gnu.gdb.aarch64.pauth only applies
to TTBR0, which is sufficient for native user-mode debugging. It
would be nice to extend this to TTBR1, so that it may be used for
gdbstub debugging, and the cpu is in EL[12].
My suggestion is simply to add pauth_{d,c}mask1 (possibly within
a different feature name). These values would be -1 when the
active translation regime does not have two VA ranges, i.e.
EL2 but not EL2&0, and EL3.
