++QEMU tracing using systemtap-initscript ++--------------------------------------- ++ ++You can capture QEMU trace data all the time using systemtap-initscript. This ++uses SystemTap's flight recorder mode to trace all running guests to a ++fixed-size buffer on the host. Old trace entries are overwritten by new ++entries when the buffer size wraps. ++ ++1. Install the systemtap-initscript package: ++ # yum install systemtap-initscript ++ ++2.

This SystemTap ++script can be customized to add or remove trace events provided in ++/usr/share/systemtap/tapset/qemu-kvm-simpletrace.stp. ++ ++SystemTap customizations can be made to qemu_kvm.conf to control the flight ++recorder buffer size and whether to store traces in memory only or disk too. ++See stap(1) for option documentation. ++ ++3.

For example, VIRT_HIGH_GIC_REDIST2 isn't needed by GICv2. +This leads to waste in the PA space. + +Add properties ("highmem-redists", "highmem-ecam", "highmem-mmio") to +allow users selectively disable them if needed. After that, the high +memory region for GICv3 or GICv4 redistributor can be disabled by user, +the number of maximal supported CPUs needs to be calculated based on +'vms->highmem_redists'. The follow-up error message is also improved +to indicate if the high memory region for GICv3 and GICv4 has been +enabled or not. + +Suggested-by: Marc Zyngier +Signed-off-by: Gavin Shan +Reviewed-by: Marc Zyngier +Reviewed-by: Cornelia Huck +Reviewed-by: Eric Auger +Message-id: 20221029224307.138822-8-gshan@redhat.com +Signed-off-by: Peter Maydell +(cherry picked from commit 6a48c64eec355ab1aff694eb4522d07a8e461368) +Signed-off-by: Gavin Shan +Conflicts: + hw/arm/virt.c + Comment out the handlers of the property 'highmem-redists', + 'highmem-ecam' and 'highmem-mmio' since they aren't exposed. +--- + docs/system/arm/virt.rst | 13 +++++++ + hw/arm/virt.c | 75 ++++++++++++++++++++++++++++++++++++++-- + 2 files changed, 86 insertions(+), 2 deletions(-) + +diff --git a/docs/system/arm/virt.rst b/docs/system/arm/virt.rst +index 4454706392..188a4f211f 100644 +--- a/docs/system/arm/virt.rst ++++ b/docs/system/arm/virt.rst +@@ -98,6 +98,19 @@ compact-highmem + Set ``on``/``off`` to enable/disable the compact layout for high memory regions. + The default is ``on`` for machine types later than ``virt-7.2``. + ++highmem-redists ++ Set ``on``/``off`` to enable/disable the high memory region for GICv3 or ++ GICv4 redistributor.

The memory layout may +be changed after the improvement is applied, which leads to potential +migration breakage. So 'vms->highmem_compact' is added to control if +the improvement should be applied.

These updates + are not atomic, especially not for KVM VCPU threads, such that we can + get spurious faults. + + Let's inhibit most KVM ioctls while performing relevant updates, such + that we can perform the update just as if it would happen atomically + without additional kernel support. + + We capture the add/del changes and apply them in the notifier commit + stage instead. There, we can check for overlaps and perform the ioctl + inhibiting only if really required (-> overlap). + + To keep things simple we don't perform additional checks that wouldn't + actually result in an overlap -- such as !RAM memory regions in some + cases (see kvm_set_phys_mem()). + + To minimize cache-line bouncing, use a separate indicator + (in_ioctl_lock) per CPU. Also, make sure to hold the kvm_slots_lock + while performing both actions (removing+re-adding). + + We have to wait until all IOCTLs were exited and block new ones from + getting executed. + + This approach cannot result in a deadlock as long as the inhibitor does + not hold any locks that might hinder an IOCTL from getting finished and + exited - something fairly unusual. The inhibitor will always hold the BQL. + + AFAIKs, one possible candidate would be userfaultfd. If a page cannot be + placed (e.g., during postcopy), because we're waiting for a lock, or if the + userfaultfd thread cannot process a fault, because it is waiting for a + lock, there could be a deadlock. However, the BQL is not applicable here, + because any other guest memory access while holding the BQL would already + result in a deadlock. + + Nothing else in the kernel should block forever and wait for userspace + intervention. + + Note: pause_all_vcpus()/resume_all_vcpus() or + start_exclusive()/end_exclusive() cannot be used, as they either drop + the BQL or require to be called without the BQL - something inhibitors + cannot handle. We need a low-level locking mechanism that is + deadlock-free even when not releasing the BQL. + + Signed-off-by: David Hildenbrand + Signed-off-by: Emanuele Giuseppe Esposito + Tested-by: Emanuele

This may not be always true, as even if a channel has a +connection established on the source side it can be in the pending state on +the destination side and a newer connection can be established first. +Basically causing out of order mapping of channels on the destination side. +Currently, all channels except post-copy preempt send a magic number, this +patch uses that magic number to decide the type of channel. This logic is +applicable only for precopy(multifd) live migration, as mentioned, the +post-copy preempt channel does not send any magic number. Also, tls live +migrations already does tls handshake before creating other channels, so +this issue is not possible with tls, hence this logic is avoided for tls +live migrations. This patch uses read peek to check the magic number of +channels so that current data/control stream management remains +un-effected. + +Reviewed-by: Peter Xu +Reviewed-by: Daniel P.
