Progress: * UM-2 [QEMU upstream maintainership] - last bits of prep and admin for Connect - investigating what we should do with the MPIDR when the user specifies a topology setup when the CPU being emulated is or is not one with MPIDR.MT set. I had written this up as a "bitesized task" in the bug system, but unfortunately it is turning out to be hairier than I had thought at the time... * QEMU-530 [QEMU ARMv9.5 Baseline CPU for TCG] - Finished and sent out patches to implement FEAT_WFxT emulation (WFI/WFE with a timeout) -- PMM

RE: [Linaro-TCWG-CI] gcc patch #89057: FAIL: 28 regressions on arm

by Andrew Pinski (QUIC)

These are all expected "failures" for arm (aarch32) really; the new testcases were known to fail for that target; it is recorded as PR 224847. I was not sure how to record this besides in the commit message. Should I xfail them for the targets that are known to fail?

Progress: * UM-2 [QEMU upstream maintainership] - made the 9.0 release and handed over pullreq processing to RTH for the 9.1 cycle - collected up and sent out the first target-arm pullreq for 9.1 - finished creating JIRA issues for QEMU for FEAT_* features to bring us into sync with the rev K.a Arm ARM * QEMU-530 [QEMU ARMv9.5 Baseline CPU for TCG] - Sent out v2 of the "make CNTFRQ 1GHz" patchset. This version includes patches to keep sbsa-ref on the old 62.5MHz frequency (since there's no TF-A release yet with the fix to make it not hardcode that value) - Started looking at FEAT_WFxT (WFI/WFE with a timeout) -- PMM

Do you only run the pre-commit regression tests with -pedantic-errors? Thanks Paul

Re: [Linaro-TCWG-CI] 3 patches in gcc: FAIL: 260 regressions on arm

by Qing Zhao

Hi, I am wondering why I got the following message? I only sent patch review request to gcc-patches(a)gcc.gnu.org<mailto:gcc-patches@gcc.gnu.org>, never committed the patches to any public repository. Are there anyone else applied the patches to sourceware and tested them? I have posted many patch review request to gcc-patches(a)gcc.gnu.org<mailto:gcc-patches@gcc.gnu.org>, this is the first time I got such message. Thanks a lot for your help.

Hi Tom. As you may have noticed, your patch below caused regressions in the libstdc++ testsuite on aarch64: FAIL: libstdc++-prettyprinters/debug.cc print redirected FAIL: libstdc++-prettyprinters/simple.cc print redirected FAIL: libstdc++-prettyprinters/simple11.cc print redirected For instance, the log contains: $24 = Traceback (most recent call last): File "/home/tcwg-buildslave/workspace/tcwg_gnu_5/abe/snapshots/gcc.git~master/libstdc++-v3/testsuite/../python/libstdcxx/v6/printers.py", line 2279, in to_string got: $24 = Traceback (most recent call last): FAIL: libstdc++-prettyprinters/debug.cc print redirected Do you know if this is a problem in GDB, or if the testcase needs an adjustment like recently for another one?

[ACTIVITY] report week ending 19 Apr

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - got rc4 out of the door; 9.0 release next week - working through the rev K.a Arm ARM to resync the list of architecture features we have implemented and the Linaro JIRA issues that track the ones we haven't. Sent a patchset that updates the QEMU documentation to the new feature names and the newly added features that previously were effectively considered part of baseline v8.0. - Sent patches that add some easy "no-op for QEMU" features: FEAT_CSV2_3, FEAT_ETS2, FEAT_Spec_FPACC. - Sorted out the last loose end in the FEAT_NMI patchseries (the cpuif should have a different "NMI supported" state to the IRI), and queued it ready for 9.1 - Queued a few other already-reviewed patchseries ready for 9.1 * QEMU-530 [QEMU ARMv9.5 Baseline CPU for TCG] - Making the generic timer default frequency be 1GHz (required for Arm v8.6 and above). I have patches for this, most of which are concerned with ensuring that for backwards-compatibility we don't use the new default on old CPU types and old versioned machines. -- PMM

Progress: * UM-2 [QEMU upstream maintainership] - looking at some late-breaking patches for various more-or-less 9.0-worthy bugs - tagged rc3; looks like we'll need an rc4, though - back to looking at cleanups and refactorings of our reset handling: + add support for a new reset type RESET_TYPE_SNAPSHOT_LOAD so we can use a new-style reset method for the kind of "load new RNG seed into memory" task we can currently only do with qemu_register_reset_nosnapshotload() or with a Machine reset method + pass the reset type into all reset phase methods, not just 'enter' + experimenting with making Machine a subclass of Device, which should let us clean up some inconsistencies (like Machine having its own reset handling that's different from everything else) -- PMM
