Progress: * UM-2 [QEMU upstream maintainership] - investigated and fixed a few bugs in FEAT_MOPS; patches sent - reviewed patch fixing bug in virt ACPI table for debug UART; added the necessary update-the-reference-files patches for 'make check'. Debugged why it broke console output on Linux -- turns out that Linux has a bug where acpi_parse_spcr() and pl011_console_match() disagree about how the former should tell the latter "use 16-bit MMIO"... We'll work around this by having the ACPI table report 32-bit MMIO; Raspberry Pi 4 firmware on real hardware already does that, so it should be a safe choice. - sent patch fixing failure to report BTI GP state correctly when doing a two-stage page table walk - code review and assembly of a pull request (softfreeze next week...) * QEMU-292 [ARMv8.3 FEAT_NV, Nested Virtualization] - got to a (hopefully) code-complete but untested state; will probably put this to one side for the moment leading up to softfreeze - tracked down the kernel and kvmtool patchsets that will be needed to test this (they are not upstream yet) thanks -- PMM

[ACTIVITY] Report for week #43

by Philippe Mathieu-Daudé

Progress: * QEMU-610 [Remove qemu_get_cpu() from hardware models] - Big rework of Cortex-A MPCore models. A common class is now used and various duplicated code from ARM boards got removed. Possible follow-up with QEMU-601 [Implement TYPE_CORTEXR52_PRIV].

[ACTIVITY] Report for week #43

by Thiago Jung Bauermann

Hello, # [GNU-981] FEAT_GCS (Guarded Control Stack) support in GDB - Started working on this feature. Currently adding ptrace and core file support for the NT_ARM_GCS regset. # Upstream community - Implemented fix for ‘--with-auto-load-dir’ and ‘--with-auto-load-safe-path’ configure options on Windows (since Eli mentioned it earlier this month) and posted “[PATCH] gdb/configure.ac: Fix auto-load options to work with Windows path separator”. -- Thiago

[weekly][linaro] report week ending 27 Oct

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - Took a prototype set of patches to add a second UART to the virt board which I'd written before going off on holiday; cleaned them up and got them into shape to send out for review. This is likely to be QEMU 9.0 material because we want to wait for the fix to EDK2 to make it handle the second uart more sensibly to get into an upstream EDK2 before landing the QEMU patches. - More code review work; sent this week's target-arm pull request * QEMU-292 [ARMv8.3 FEAT_NV, Nested Virtualization] - Started on implementation. This seems to be shaping up to be a less difficult task than our initial estimate suggested; I have code-complete patches for most of the necessary behaviour changes already. (Testing may be a more drawn-out effort :-)) -- PMM
