[PATCH v2 0/2] makedumpfile/arm64: Add support for ARMv8.2 extensions

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Changes since v1:
----------------
- v1 was sent as two separate patches:
  http://lists.infradead.org/pipermail/kexec/2019-February/022424.html
  (ARMv8.2-LPA)
  http://lists.infradead.org/pipermail/kexec/2019-February/022425.html
  (ARMv8.2-LVA)
- v2 combined the two in a single patchset and also addresses Kazu's
  review comments.

This patchset adds support for ARMv8.2 extensions in makedumpfile code.
I cover the following two cases with this patchset:
 - 48-bit VA + 52-bit PA (LPA)
 - 48-bit kernel VA + 52-bit virtual VA (LVA)

This has been tested for the following user-cases:
1. Calculating --mem-usage on the primary kernel,
2. Creating a dumpfile using /proc/vmcore, and
3. Post-processing a vmcore.

I have tested this patchset on the following platforms, with kernels
which support/do-not-support ARMv8.2 features:
1. CPUs which don't support ARMv8.2 features, e.g. qualcomm-amberwing,
   ampere-osprey.
2. ARMv8 FVP model, which supports ARMv8.2 extensions.
