Bugzilla: https://bugzilla.tianocore.org/show_bug.cgi?id=2122
Repo: https://pagure.io/lersek/edk2.git
Branch: xen_split_bz_2122
This patch set removes dynamic Xen enlightenment from the following
platforms:
OvmfPkg/OvmfPkgIa32.dsc
OvmfPkg/OvmfPkgIa32X64.dsc
OvmfPkg/OvmfPkgX64.dsc
In Xen guests, the following platform should be used:
OvmfPkg/OvmfXen.dsc
Please see more details / references in the bugzilla ticket.
NOOPT build savings:
- Ia32: PEIFV 1536 bytes, DXEFV 130288 bytes
- Ia32X64: PEIFV 1536 bytes, DXEFV 140912 bytes
- X64: PEIFV 1664 bytes, DXEFV 140912 bytes
- Xen: PEIFV 256 bytes, DXEFV 69504 bytes
Functional testing:
- Booted a Fedora guest on OvmfPkgIa32X64 on QEMU/KVM, compared verbose
logs before-after. Memory allocations were satisfied at different
addresses, as expected, plus the Xen drivers were absent. No
differences otherwise.
- Booted a RHEL guest on ArmVirtQemu on AARCH64. Memory allocations were
satisfied at different addresses, as expected.
- Xen regression-testing was not done; I'm requesting feedback.
Build testing / bisectability: at every stage, the series builds with
the following script:
> #!/bin/bash
> set -e -u -C
>
> build -b DEBUG -t GCC5 -p ArmVirtPkg/ArmVirtKvmTool.dsc -a AARCH64
> build -b DEBUG -t GCC5 -p ArmVirtPkg/ArmVirtKvmTool.dsc -a ARM
> build -b NOOPT -t GCC5 -p ArmVirtPkg/ArmVirtQemu.dsc -a AARCH64

The patches in the series were formatted with the following options, for
posting:
--stat=1000 --stat-graph-width=20 --find-copies-harder -U6
(The option "--find-copies-harder" is not the best for presenting every
single patch in the series, in isolation, but taken globally for the
entire series, it is the most helpful option.)
Some patches advance with really small steps, in order to cut down on a
subsequent "meaty" patch. Personally I don't like reviewing code
movement patches, so I did my best to (a) keep that to a minimum, and
(b) present it as unintrusively as possible.
The CC list is a bit long; the reason is that I kept touching up
"Maintainers.txt", and the "OvmfPkg/Bhyve" and "OvmfPkg/AmdSev"
platforms as well (whenever it made sense).
