[Xen-devel] [PATCH net-next v2] xen-netback: make copy batch size configurable

Commit eb1723a29b9a ("xen-netback: refactor guest rx") refactored Rx handling and as a result decreased max grant copy ops from 4352 to 64. Before this commit it would drain the rx_queue (while there are enough slots in the ring to put packets) then copy to all pages and write responses on the

[Xen-devel] [PATCH 1/2] x86/svm: Add SVME checking for SVM intercepts

Checks the hvm EFER.SVME bit to make sure the EFER.SVME bit it high before allowing nested SVM intercepts to be handled successfully. On SVME being low, it generates a #UD as per the AMD APM vol2 15.4. Reported-by: Andrew Cooper Signed-off-by: Brian Woods

[Xen-devel] [PATCH] xen/efi: Avoid EFI stub using absolute symbols

The EFI image should be relocatable. At the moment, all the stub is relocatable but one place. On both Arm64 and x86-64 (from a quick glance) , the compiler will generate absolute pointer in the ErrCodeToStr array. Those values are based on Xen view of the virtual memory and may not be the same

Re: [Xen-devel] Xen Performance Results

Hi all, For the sake of completeness: the solution to the issue stated in my last email was deactivating Intel's Turbo Boost technology directly in UEFI (deactivating Turbo Boost through xenpm was not enough). Apparently Turbo Boost affects Linux and KVM differently than Xen, which led to the

[Xen-devel] [PULL 08/25] pci: Eliminate redundant PCIDevice::bus pointer

From: David Gibson The bus pointer in PCIDevice is basically redundant with QOM information. It's always initialized to the qdev_get_parent_bus(), the only difference is the type. Therefore this patch eliminates the field, instead creating a pci_get_bus() helper to
