xen/mcelog: Add __nonstring annotations for unterminated strings

2025-04-25T08:45:11+00:00

[ Upstream commit 1c3dfc7c6b0f551fdca3f7c1f1e4c73be8adb17d ] When a character array without a terminating NUL character has a static initializer, GCC 15's -Wunterminated-string-initialization will only warn if the array lacks the "nonstring" attribute[1]. Mark the arrays with __nonstring to and correctly identify the char array as "not a C string" and thereby eliminate the warning.

x86/PVH: obtain VGA console info in Dom0

2023-03-14T14:20:51+00:00

A new platform-op was added to Xen to allow obtaining the same VGA console information PV Dom0 is handed. Invoke the new function and have the output data processed by xen_init_vga().

x86/xen: Add support for HVMOP_set_evtchn_upcall_vector

2022-08-12T09:28:21+00:00

Implement support for the HVMOP_set_evtchn_upcall_vector hypercall in order to set the per-vCPU event channel vector callback on Linux and use it in preference of HVM_PARAM_CALLBACK_IRQ. If the per-VCPU vector setup is successful on BSP, use this method for the APs. If not, fallback to the global vector-type callback. Also register callback_irq at per-vCPU event channel setup to trick toolstack to think the domain is enlightened.

The hypervisor has been supplying this information for a couple of major releases. Make use of it. The need to set a flag in the capabilities field also points out that the prior setting of that field from the hypervisor interface's gbl_caps one was wrong, so that code gets deleted (there's also no equivalent of this in native boot code).

usb: Add Xen pvUSB protocol description

2021-12-13T13:58:31+00:00

Add the definition of pvUSB protocol used between the pvUSB frontend in a Xen domU and the pvUSB backend in a Xen driver domain (usually Dom0). This header was originally provided by Fujitsu for Xen based on Linux 2.6.18. Changes are: - adapt to Linux kernel style guide - use Xen namespace - add lots of comments - don't use kernel internal defines Reviewed-by: Boris Ostrovsky Signed-off-by: Juergen Gross Link: https://lore.kernel.org/r/20211123132048.5335-2-jgross@suse.com Signed-off-by: Greg Kroah-Hartman
