Morello
- Upstream LLD INPUT_SECTION_FLAGS that I implemented downstream.
Quite a few review comments to work through but I think I'm close to
getting something accepted. This will hopefully come in useful for LLD
with embedded systems.
- Wrote down some definitions for the new relocations.
LLD
- landed fix for clang-built-linux-812 linux allyesconfig problem.
- Quite a few upstream LLD and MC reviews
Other
Some research for the clang built linux conference.
== Progress ==
* Out of office for 2 days
* Reviewed EuroLLVM submissions
* A bit more investigation into Morello bare metal debugging
== Plan ==
* PR44157
* Morello bare metal debugging
Hello Linaro team,
I want to use your cross compiler version 6.3.1, but I miss the library
asound and its header (alsa/asoundlib.h)
What do I need to do to fix this ?
Best regards,
Markus Bollinger
Hi Ana,
I don't know anything about the POC myself, but I'm forwarding this so our
QEMU folks can answer.
Cheers,
Diana

Subject: about QEMU support for SVE2 POC
To: diana.picus(a)linaro.org <diana.picus(a)linaro.org>
Cc: Ana Pazos <apazos(a)quicinc.com>
Hello Diana,
We at Qualcomm are trying to find out the POC for QEMU support for SVE2.
We have been using QEMU with SVE support, and need to find out when SVE2
support will be added to QEMU.
I assume Linaro is involved in this task. Do you know the POC?
Thanks for the help!
Ana.
== Progress ==
* BFD Linker:
- GNU-629: non-contiguous memory support: sent updated versions with
testcases and doc.
* GCC:
- trying to find a way to add run more validation of -mpure-code on
v6m, to support a request to backport to gcc-9
- proposal to implement LLVM's -arm-assume-misaligned-load-store
rejected by the community
* GCC upstream validation:
- reported/checked a few issues
* misc:
- infra fixes / troubleshooting / reviews
- investigating problems with automatic bisection of gcc regressions
- fixed a long-standing bug in proot
== Next ==
* Binutils: GNU-629: support non-contiguous memory regions in linker
[VIRT-327 # Richard's upstream QEMU work ]
* TCG patch queue flush, including phase 1 increase for
number of mmu_idx, on which VHE is dependent.
* Random patch review.
* Capstone update.
* cputlb cleanup in prep for modeling ASIDs.

Morello:
- Implemented INPUT_SECTION_FLAGS in LLD for the Morello toolchain,
now in review. Took most of spare engineering time this week. Will
attempt to upstream once committed in Morello
- Fixed pr44451 upstream, it was already fixed on Morello toolchain.
LLD:
- Made an attempt to fix the LLD linux kernel allyesconfig +
cortex-a53 erratum problem. Was not successful as kernel linker script
is just about as awkward as possible for this problem. I have a good
idea of what to try next. Will aim to fix early next week.
- Quite a few upstream reviews, some pending from last year.
Progress:
* VIRT-65 [QEMU upstream maintainership]
- caught up on the backlog of email that accumulated over the Christmas break
- investigated an intermittent failure of a test case on our BSD hosts
which had reached a failure rate that was seriously impeding the
flow of pull requests. Tracked it down to glib's g_source_ref/unref
not being thread-safe unless the GSource is attached to a GMainContext;
QEMU gets this right for its own use but a set of mock functions used
for a few testcases were not doing so, resulting in occasional races
where the GSource would get destroyed while it was still in use.
- code review:
+ Beata's "inject DABT for load/store insns KVM couldn't emulate" patch
+ a minor cubieboard cleanup patchset
+ i.MX RNGC device emulation patch
- annual review season, some time spent on that
thanks
