[ACTIVITY] report week ending 1 Dec

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - Sent a pullrequest for this week's rc - Sent a patch which disables SME if SVE is disabled, since QEMU currently asserts if you try to use that combination. * QEMU-623 [Nested Virtualization Emulation] - Mostly working through debugging issues in my FEAT_NV/FEAT_NV2 emulation. I can get the inner guest kernel to boot up to the point where it tries to 'eret' and the outer kernel thinks that's an invalid exception return. More debugging scheduled for next week... -- PMM

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - Usual amount of code review and upstream pull request wrangling * QEMU-623 [Nested Virtualization Emulation] - Since the kernel side of KVM has decided that FEAT_NV alone is not worth supporting, I'm moving on to implementing FEAT_NV2 rather than trying to debug whether the behaviour I've been seeing is a bug in the kernel patchset's not-really-tested FEAT_NV handling. - I have a code-complete implementation of FEAT_NV2.

[ACTIVITY] report week ending 16 Nov

by Peter Maydell

Progress (short week, 3 days): * UM-2 [QEMU upstream maintainership] - put together pull request for a handful of bugfixes for rc0 - fixed the FEAT_MOPS reverse-copy bug and sent a patch for it * QEMU-292 [ARMv8.3 FEAT_NV, Nested Virtualization] - trying to get a setup with kvmtool and a kernel with the WIP FEAT_NV support working. I now have a setup that works when you don't ask for the inner-guest to have EL2 support, but when you do enable --nested it boots the inner-guest fine and then hangs at about the point where it should be mounting the rootfs. This might be tedious to debug... -- PMM

[ACTIVITY] report week ending 10 Nov

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - Noticed that if the guest uses the HVC insn at EL3 we incorrectly take the exception to EL2, not EL3; sent a patch to fix this - looking into an issue with FEAT_MOPS copies going backwards across page boundaries * QEMU-292 [ARMv8.3 FEAT_NV, Nested Virtualization] - realised we need to do some cleanup of how we handle the FEAT_VHE register aliases, as the way we currently do them makes the FEAT_NV register trapping a little awkward. Wrote the necessary patches; they'll go into the FEAT_NV patchset when it's eventually ready to send out. -- PMM

I'd certainly encourage the relevant target maintainers to investigate and fix the failing tests (which probably indicate a back-end change is needed to make variable argument access work correctly in a function with no named arguments - some architectures were fixed by the change in bug 107453, but it wouldn't be surprising if other architectures need back-end changes). -- Joseph S.

[ACTIVITY] Report for week #44

by Thiago Jung Bauermann

Hello, # TCWG CI - Working on Abe change to always add detected flaky tests to the flaky.xfail file, even if they are already present in the baseline results. Sent a few versions of Gerrit review request already. # [GNU-981] FEAT_GCS (Guarded Control Stack) support in GDB - Prepared environment to develop and test GDB: built Linux kernel from Mark Brown's arm64-gcs branch and booted it in an Arm FVP supporting the feature. Successfully ran native GDB in it to debug a program (though I didn't use any GCS feature for this test). -- Thiago

[ACTIVITY] report week ending 3 Nov

by Peter Maydell

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 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

Re: [PATCH v2] ARM: Block predication on atomics [PR111235]

With this it runs a few more tests. Yeah that's a wart that I don't like. armhf just implies the hard float ABI and came into being to help distinguish from the Base PCS for some of the distros at the time (2010s). However we didn't want to set a baseline arch at that time given the imminent arrival of v8-a and thus the specification of --with-arch , --with-fpu and --with-float became second nature to many of us working on it at that time. I can see how it can be confusing. With the advent of fpu=auto , I thought this could be made better but that is a matter for another patch and another discussion. However until then do remember to baseline to --with-arch , --with-fpu and --with-float . Unfortunate but needed. If there is a bug with --with-fpu=auto , good to articulate it as I understand that to be the state of the art.

Please try out various combinations of -march v7ve, v7-a , v8-a with the tool as each of them have slightly different rules. For instance v7ve allows LDREXD and STREXD to be single copy atomic for 64 bit loads whereas v7-a did not . > > > -(define_insn "atomic_load<mode>" > > - [(set (match_operand:QHSI 0 "register_operand" "=r,r,l") > > +(define_insn "arm_atomic_load<mode>" > > + [(set (match_operand:QHSI 0 "register_operand" "=r,l") > > (unspec_volatile:QHSI > > - [(match_operand:QHSI 1 "arm_sync_memory_operand" "Q,Q,Q") > > - (match_operand:SI 2 "const_int_operand" "n,Pf,n")] ;; model > > + [(match_operand:QHSI 1 "memory_operand" "m,m")] > > > > Remind me again why is it safe to go from the Q constraint to the m > > constraint here and everywhere else you've done this ? > > That's because the relaxed loads/stores use LDR/STR wrapped in an > UNSPEC.

While it is not policy yet to look at these bots but given the enthusiasm at Cauldron for patchwork and pre-commit CI and because all my armhf boxes are boxed up, I decided to do something a bit novel ! I tried reviewing this via patchwork https://patchwork.sourceware.org/project/gcc/patch/PAWPR08MB8982A6AA40749B7… and notice that https://ci.linaro.org/job/tcwg_gcc_build--master-arm-precommit/2393/artifac… says nothing could be built. Possibly worth double checking the status for it being a false negative as to why the build failed. It was green on patchwork but remembering that Green is not Green for CI in patchwork I clicked on the afore mentioned ci.linaro.org link and see that it's actually broken. regards Ramana

[ACTIVITY] Report for week #41

by Thiago Jung Bauermann

Hello, # TCWG CI - Flakiness in gdb.base/gdb-sigterm.exp causes false positives on tcwg_check_gdb--master-arm-precommit, so started investigating its failures. - Investigated regressions reported by the CI: - GCC regression GNU-935: Not a real regression, just already existing failures being reported for a new version of the C++ standard. - linux-next regression GNU-936: Fixed in the newest linux-next tree. - GCC regression GNU-962: Opened GCC bug 111802 ("New analyser diagram failures since commit b365e9d57ad4"). - GCC regression GNU-965: Arm already opened GCC bug 111784 ("[14 Regression] aarch64: ldp_stp_{15,16,17,18}.c test failures since r14-4579.") about this issue. - GCC regression GNU-966: This problem has been fixed in trunk. - linux-next regression GNU-967: A patch was sent to fix the error. # [GNU-767] Support changing SVE vector length in remote debugging - Working on adapting gdbserver's regcache to support registers with a variable size. - Also enabling the target description XML to express vector register sizes in terms of another register. -- Thiago

Fwd: [Linaro-TCWG-CI] llvmorg-18-init-7933-ge13bed4c5f35: slowed down by 6% - 464.h264ref on aarch64 O2

by Maxim Kuvyrkov

Hi Dmitriy, Linaro Benchmarking CI has flagged several interesting code-speed and code-size regressions for your patch -- see [1]. In particular, could you check if below regressions can be avoided: - grew in size by 21% - 473.astar:[.] _ZN7way2obj12releasepointEii - slowed down by 61% - 505.mcf_r:[.] price_out_impl Both of these are for 32-bit ARM, but AArch64 also has code-speed and code-size regressions. Let me know if you need any assistance in reproducing these problems.

[ACTIVITY] Report for weeks #37 to #40

by Thiago Jung Bauermann

Hello, Attended two events in a row in September, so had a bit of a time crunch and the weekly report fell through the cracks... # TCWG CI - Investigated and fixed a few false positives in the GDB precommit CI which were caused by random failures in gdb.threads/process-dies-while-detaching.exp. Posted upstream and later committed patch fixing the testcase to be more stable. - After conversations during GNU Tools Cauldron and following Maxim's suggestion, changed Linaro's CI to use the read1 library while running the GDB testsuite to improve the stability of its results. - After review from Tom Tromey, posted v2 and later committed a patch which adds '--with-additional-debug-dirs' configure option. - Committed a couple of changes to our CI scripts which make sure that the kernel.yama.ptrace_scope and kernel.core_pattern sysctls have correct values for running the GDB testsuite. # [GNU-767] Support changing SVE vector length in remote debugging - Now that Luis pushed his SME and SME2 patches, merged current GDB main branch into my local branch. It builds but doesn't work yet. # GDB Upstream - Reviewed patch series "[PATCH v3 0/4] Dynamic properties of pointers". - Investigated upstream bugzilla "18898 - Cannot specify non-default list of directories as argument of --with-auto-load-dir on Windows", but concluded it's an autoconf limitation that isn't easy to fix. # Misc - Prepared for Linaro's Employees Meeting. - Attended GNU Tools Cauldron. - Took a few days of vacation. -- Thiago

[weekly][linaro] report week ending 22 Sep

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - Implemented Neoverse N2 CPU model (easy as it's very similar to the Cortex-A710 we just implemented; but because it supports 48 bit physical addresses we can use it in the sbsa-ref board, so it's worth having both) - Wrote code to wire up the NS EL2 virtual timer IRQ on the virt board. This is part of FEAT_VHE, and we implemented the timer itself in the CPU ages ago, but forgot to ever wire up the interrupt line on the board models. Unfortunately doing this runs into a bug in EDK2 where it incorrectly asserts when it sees a dtb that reports the interrupt line. Leif Lindholm wrote patches to fix this in EDK2, but we'll need to update the QEMU testsuite and figure out how to communicate the need for an updated EDK2 to users. - Looked again at a long-standing missing feature in the virt board where it only has one UART. The main blocker for adding a second one has been odd EDK2 behaviour when the dtb tells it there are two UARTs. Investigated and wrote up exactly what it does to start a discussion about improving it. - Put together a target-arm pull request - Squashed a few -Wshadow warnings - Looking at a bug involving QEMU's PSCI emulation when QEMU is faking being EL3 firmware for a Linux guest * QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG] - Implemented and sent a patch for FEAT_HPMN0 (a very easy feature that makes MDCR_EL2.HPMN==0 valid) -- PMM

[ACTIVITY] report week ending 15 Sep

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - sent patches that re-sync our defined set of usermode hwcap bits and ID register bitmasks with what the Linux kernel currently has - code review * QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG] - FEAT_HBC: wrote and sent patch for this very simple feature - FEAT_MOPS: rolled v2 patchset based on review feedback * QEMU-486 [Update QEMU device models for FEAT_RME] - Looked at the SMMU spec to see (a) what realm-management related changes it needs and (b) where we are on the implementation of other features. Closed a few stale JIRA issues for features we've already implemented. - sent a patchset that advertises that we support SMMUv3.1-XNX (this is a no-op for our implementation) - investigated what the "expected" setup is for enforcing GPT checks on the GIC/ITS. Current front-runner is "the SMMU that's already in the system provides 'GPC checks only' for the accesses from these devices, as well as stage1/stage2 + GPT checks for PCI etc devices" (the term in the SMMU spec rev F.a is for a GPC-checks-only client device is "NoStreamID device") -- PMM

It looks like other NSS tests also fail in the same way. Is this a known issue on arm? Thanks, Sid

Fwd: [Linaro-TCWG-CI] gcc patch #75644: FAIL: 2 regressions

by Jonathan Wakely

I think this is because the patch changes libstdc++-v3/include/bits/version.def which requires version.h to be regenerated, by running 'make update-version' in the objdir/$target/libstdc++-v3/include directory. The patch I sent to gcc-patches (which is archived in patchwork) doesn't have the updates to the generated files, but what I committed to git does have them. ---------- Forwarded message --------- From: <ci_notify(a)linaro.org> Date: Mon, 11 Sept 2023 at 21:00 Subject: [Linaro-TCWG-CI] gcc patch #75644: FAIL: 2 regressions To: <jwakely(a)redhat.com> Dear contributor, our automatic CI has detected problems related to your patch(es).

[ACTIVITY] Report for week #36

by Thiago Jung Bauermann

Hello, # [GNU-767] Support changing SVE vector length in remote debugging - Continuing work on new approach to support changing SVE vector length in remote debugging. Fixed making native GDB work with the new approach using the DWARF location expression. Now porting the same approach to gdbserver, with an ad-hoc minimal location expression. # TCWG CI - Fixed GDB testsuite default timeout value, to make GDB check jobs for 32-bit ARM run in a less unreasonable time again. # Misc - Started preparation for future work on Guarded Control Stack for GDB. -- Thiago

[ACTIVITY] Report for week #35

by Thiago Jung Bauermann

Hello, # [GNU-767] Support changing SVE vector length in remote debugging - Resumed working on new approach to support changing SVE vector length in remote debugging. I was able to use DWARF location expressions in the target description to express the SVE vector register sizes in terms of the VG register. Also adapted the regcache to support variable-length registers, and removed the VQ value from the target description and from aarch64_gdbarch_tdep, making GDB use one target description regardless of the vector length size. Still ironing out some bugs, and haven't tackled gdbserver yet. -- Thiago

Re: [EXT] [Linaro-TCWG-CI] 2 patches in gcc: FAIL: 1 regressions

by Andrew Pinski

Just FYI. This test is just bogus and fixing it might be simple as using -fsanitize=undefined to check at runtime there is no undefined behavior being hit. In this case even if we do the comparison in `signed` and do the negate in `unsigned` types. we can still remove the negate in this case since we know the only value that will be still negative in that branch is LONG_MIN. So my patch just simplifies the inner comparison to that instead of `a < 0` and then be able to remove the neg. Someone else will have to fix the testcase since it is a testcase issue ... ________________________________________ From: ci_notify(a)linaro.org <ci_notify(a)linaro.org> Sent: Friday, September 1, 2023 3:07 PM To: Andrew Pinski Subject: [EXT] [Linaro-TCWG-CI] 2 patches in gcc: FAIL: 1 regressions External Email ---------------------------------------------------------------------- Dear contributor, our automatic CI has detected problems related to your patch(es).

I did a quick analysis and it seems that for test_copy_lane_f32, test_copy_lane_s32, test_copy_lane_u32, gcc is now generating zip1 instead of a ins; which does not seem fully correct.

[ACTIVITY] Report for week #33

by Thiago Jung Bauermann

Hello, # [GNU-767] Support changing SVE vector length in remote debugging - Continued working on new approach to support changing SVE vector length in remote debugging. # TCWG CI - Analysed GCC regression GNU-880 which is actually an XFAIL → XPASS so I sent a patch removing the xfail annotation. - Analysed GCC regression GNU-881. The problem is that we don't have Python in the ABE sysroot so a new Python GCC plugin testcase fails to build. Sent a patch to detect that situation and mark the test as unsupported. It was committed upstream. - Tested a couple of new versions of a GDB mailing list patch to see if it fixed the failure reported by the precommit CI. Reported results to patch author. - Fixed silly mistake spotted by Laurent in ABE Gerrit requests to use TIMEOUTFACTOR for DejaGnu testsuites. Adjusted it to not use the factor in GDB on armhf and sent new version for review. - Reviewed a couple of Gerrit requests. -- Thiago

Progress (short week, 3 days): * UM-2 [QEMU upstream maintainership] - sent out another couple of "avoid VLA" patches * QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG] - managed to write some first-pass code for the MTE checks for FEAT_MOPS memset operations. Got something together enough to send to RTH for some pre-review before I roll the approach out to the other insns. -- PMM

Hello! You are the point of contact for some build bots in the LLVM build lab that have been down for an extended period of time. If you're not the correct point of contact, can you please CC the right individual (if you know who they are)? The following bot(s) appear to have been down for multiple weeks: https://lab.llvm.org/buildbot/#/builders/clang-armv7-global-isel https://lab.llvm.org/buildbot/#/builders/clang-native-arm-lnt-perf https://lab.llvm.org/buildbot/#/builders/clang-aarch64-sve-vla-2stage https://lab.llvm.org/buildbot/#/builders/clang-aarch64-sve-vls-2stage https://lab.llvm.org/buildbot/#/builders/clang-aarch64-sve-vls https://lab.llvm.org/buildbot/#/builders/clang-armv7-vfpv3-full-2stage https://lab.llvm.org/buildbot/#/builders/clang-thumbv7-full-2stage Do you have plans to bring the bot back online? If not, that's okay -- just let me know and I can remove the bots from the lab for you. Thank you! ~Aaron

[ACTIVITY] Report for week #32

by Thiago Jung Bauermann

Hello, # [GNU-767] Support changing SVE vector length in remote debugging - Returned to implementing support for changing SVE vector length in remote debugging. The patch series I sent earlier this year used an approach that some maintainers weren't enthusiastic about (modifying the Remote Serial Protocol to request XML target descriptions). Now trying the approach they suggested, which is to extend target descriptions to support expressing vector registers whose length is given by the contents of another register. # TCWG CI - Following Maxim's suggestion, sent and merged Gerrit review requests to increase chance of tcwg_gdb_check jobs to be faster at detecting new or newly expired flaky tests: - 45151: tcwg_gdb: Increase job frequency - 45152: round-robin.sh (build_abe): Increase time to re-detect GDB flaky tests - Implemented change in ABE to support glibc's TIMEOUTFACTOR environment variable for DejaGnu testsuites. Testing on armv8l and aarch64. -- Thiago

Progress: * UM-2 [QEMU upstream maintainership] - code review, notably: + RTH's setnegcond series + Jean-Philippe's fixes for various FEAT_RME bugs + Akihiko's series to make KVM '-machine none' not default to 40 bits of IPA space if the host doesn't supoprt that (like the Apple CPUs) - sent a patch to catch the illegal exception return case from EL3 with bad SCR_EL3.{NSE,NS} - respin and resend of ptw cleanup patchset - tidied another 'BiteSizedTask' entry into a gitlab issue - went back to an old minor cleanup task: getting rid of the last dozen or so uses of variable-length arrays in the codebase (so we can enforce not using them in the compiler, and avoid unchecked-on-stack-allocation security bugs). Sent patches to zap a few more. * QEMU-530 [QEMU ARM v9.4 Baseline CPU for TCG] - thinking a bit more about FEAT_MOPS and MTE checks, but ultimately not much progress: didn't find enough hours with a sufficiently alert mind... -- PMM

[ACTIVITY] report week ending 14 Jul

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - investigated and fixed a bug in page-table-walk handling of debug accesses that was introduced by the FEAT_RME changes - that prompted me to look at a cleanup of some of the ptw code so that we consistently look at "which space is this walk for" and don't carry around a parallel boolean "secure/non-secure" that duplicates that information - found and fixed a few other ptw bugs along the way -- PMM

[ACTIVITY] Report for week #27

by Thiago Jung Bauermann

Hello, # TCWG CI - Changed tcwg_gnu-build.sh to apply GDB patch adding '--with-additional-debug-dirs' option, and ABE's gdb.conf to use it. Also changed both to add '--prefix /usr' option to GDB's configure. Both changes to fix ld.so debug info issues in GDB testsuite runs on armhf. - Testing changes to validate_failures.py and jenkins-scripts to handle empty gdb.sum. - Reviewed a few Gerrit requests. -- Thiago

[ACTIVITY] report week ending 6 Jul

by Peter Maydell

Progress (short week, 3 days): * UM-2 [QEMU upstream maintainership] - softfreeze is next week, so spent some time putting together a pull request, fixing the bugs which the CI tests found in it, etc * QEMU-422 [QEMU Arm Neoverse V1 vCPU for TCG] - now that we implement all the necessary features (excluding some trace/profiling type stuff that is out-of-scope for QEMU, and also FEAT_NV that we might come back to later), sent out the patchset to define a 'neoverse-v1' CPU type for QEMU -- PMM

[ACTIVITY] Report for week #25

by Thiago Jung Bauermann

Hello, # TCWG CI — GDB - Investigated why the GDB check jobs stopped succeeding, as reported by Maxim. It turns there was an upstream commit (which was soon reverted) that broke generation of the gdb.sum file and consequently our baseline results became empty. Theoretically the CI should recover from that but we don't deal well with this corner case. With Maxim's help, restored the baseline and now things should be back to normal. Will improve our scripts to avoid this trap. # CI Babysitting This week was my turn to baby sit the CI. - Investigated 12 regressions in GCC and reported 3. The others were already fixed. - Investigated 1 regression in GDB but it wasn't actually one. - Investigated 1 regression in QEMU but it was already fixed. -- Thiago

[ACTIVITY] report week ending 23 Jun (inc. KVM Forum trip report)

by Peter Maydell

Progress: * UM-2 [QEMU upstream maintainership] - catch up on email after a week away - Put together some arm pull requests - sent out draft QEMU summit minutes for review - sent patch to avoid using the buggy __builtin_subcll in Apple Clang 14 - sent patch fixing build error with newer xkeyboard-data - some gardening of Coverity issue reports Last week was KVM Forum in Brno -- here's a quick trip summary: This year KVM Forum was a slightly smaller conference (2 days, single-track), as we are now organizing it independently of the Linux Foundation. The independent organization went pretty well this year (despite the slightly awkward short notice) and the conference was very useful both for the talks and for the hallway track. Interesting talks (just a sampling biased to my interests): * KVM: Arm Confidential Compute Architecture Support Suzuki Poulose presented a summary of FEAT_RME and the CCA hardware and software architecture, and how it's intended to fit into KVM * KVM/arm64: Episode V - The Blob Strikes Back Immediately following was Marc Zyngier and Oliver Upton from Google: their talk was a pretty strong critique of the CCA software stack architecture. Their central point is that having the RMM be "part of the firmware" rather than "part of the hypervisor" is going to cause a rerun of all the issues we've seen with dubious and non-upgradable vendor code in EL3. Secondly, having the fixed API between the hypervisor and the RMM restricts to least-common-denominator and provides no room for experimentation and optimizations. They want an architected way to deploy an RMM at boot time. * Handling complex guest exits with eBPF Will Deacon presented what he described as "conference driven development" -- an interesting prototype of having device models in the host kernel that are implemented in eBPF. This (in theory) gives you the performance gains of an in-kernel device without it putting a lot of C code onto the security boundary between the guest and host. * Challenges Revisited in Supporting Virt CPU Hotplug on architectures that don't Support CPU Hotplug (like ARM64) James Morse (Arm) and Salil Mehta (Huawei) presented on CPU hotplug. The underlying problem here remains that Arm has no hardware hotplug handling, so there's no clear model for what hotplug on a VM should look like. Cloud vendors have an obvious desire for the x86-style tooling to Just Work on Arm too. The gap between "we have a prototype that seems to work" and "upstreamable maintainable code" has not yet been bridged, though... * QEMU Arm CPU models and KVM Cornelia Huck (RedHat) had a talk that was intended as a statement of the problem rather than a proposed solution. At the moment we only let a KVM guest see the same CPU type as the host and don't have a mechanism for presenting a subset of features to it. KVM is about to get support for letting the VMM define what the guest should see in the ID registers, but how should we expose that to QEMU users without ending up with a thousand command line sub-options to turn on and off every architectural FEAT_FOO? And how do we deal with errata workarounds, which the guest currently selects based on the MIDR value? As usual, we held the QEMU Summit (an hour-long maintainer discussion mostly about process and organizational issues) during KVM Forum. I still need to write up the minutes for this, but they'll be published on the qemu-devel list shortly. thanks -- PMM

Need emit_expr to write right shifted value.

by zac.walker＠linaro.org

Hi, In binutils I need to write an offset between two symbols shifted right by 2 bits. This offset is written to the xdata section. My code currently looks like this: exp.X_op = O_subtract; exp.X_add_symbol = symbol1; exp.X_op_symbol = symbol2; emit_expr (&exp, 2); This works fine but obviously the result value is not shifted. Anyone have a good option is to shift the output of emit_expr at write time? I cannot use resolve_expression because the symbols do not have correct addresses at the time this code executes. Any help appreciated, Zac
