[ACTIVITY] report week ending 25 Jan

[Peter Smith]

Majority of the week spent preparing for Fosdem talk on LLD:
- Built Chrome for Arm and AArch64 to investigate link time
performance on non-X86 platforms
-- Both gold and bfd take a considerable amount of time to produce
stubs/veneers/errata fixes
-- AArch64 link time is comparable to X86
- LLD gets more usage out of multithreading than gold
- Studied Gold and BFD structure to compare to LLD
- About half of slides written.

Some minor involvement with some investigations for ClangBuiltLinux.

[ACTIVITY] report week ending 25 Jan

[Peter Maydell]

Progress:
 * VIRT-65 [QEMU upstream maintainership]
  + code review:
   - 'SBSA reference' model (now quite close to being in shape to go in)
   - RTH's BTI patchset
   - RTH's patchset adding TBI support to user-mode emulation
  + sent patches fixing the last lot of clang
-Waddress-of-packed-member warnings
  + had another look at the prototype work I did to use Sphinx
for QEMU's documentation -- updated the patchset and started
looking at how to tie it into our makefiles.
  + sent patches fixing a handful of underdecodings in our A64 decoder,
where we should have UNDEFed but did not
 * VIRT-268 [QEMU support for dual-core Cortex-M Musca board]
  + sent out v1 of the patchset implementing the SSE-200 and MPS2 AN521 model
  + read through the Musca-B1 docs to confirm what we can easily
put into an initial implementation of a model

thanks
