Subject: [PATCH v2 0/2] KVM: arm64: nv: Expose shadow page tables in debugfs
Date: Tue, 17 Mar 2026 18:26:36 +0000 [thread overview]
Message-ID: <20260317182638.1592507-1-weilin.chang@arm.com> (raw)
Hi,
This is v2 of exposing shadow page tables in debugfs, there are a few
small improvements, please see below.
Changes in v2:
- move debugfs_nv_dentry also behind CONFIG_PTDUMP_STAGE2_DEBUGFS
- use a macro to define the file names of shadow ptdumps, also
explicitly spell out the string to get its maximum size
- add Reviewed-by tag from Sebastian (thanks!)
- Link to v1: https://lore.kernel.org/kvmarm/20260308231829.864983-1-weilin.chang@arm.com/
