415dab3c - drivers/xen/hypervisor: Expose Xen SIF flags to userspace

Tue, 03 Jan 2023 13:02:13 +0000

drivers/xen/hypervisor: Expose Xen SIF flags to userspace/proc/xen is a legacy pseudo filesystem which predates Xen supportgetting merged into Linux. It has largely been replaced with morenormal locations for data (/sys/hypervisor/ for info, /dev/xen/ foruser devices). We want to compile xenfs support out of the dom0 kernel.There is one item which only exists in /proc/xen, namely/proc/xen/capabilities with "control_d" being the signal of "you're inthe control domain". This ultimately comes from the SIF flags providedat VM start.This patch exposes all SIF flags in /sys/hypervisor/start_flags/ asboolean files, one for each bit, returning '1' if set, '0' otherwise.Two known flags, 'privileged' and 'initdomain', are explicitly named,and all remaining flags can be accessed via generically named files,as suggested by Andrew Cooper.Signed-off-by: Per Bilse Reviewed-by: Juergen Gross Link: https://lore.kernel.org/r/20230103130213.2129753-1-per.bilse@citrix.comSigned-off-by: Juergen Gross List of files: /linux-6.15/Documentation/ABI/stable/sysfs-hypervisor-xen

doc,xen: document hypervisor sysfs nodes for xenToday only a few sysfs nodes under /sys/hypervisor/ are documentedfor Xen in Documentation/ABI/testing/sysfs-hypervisor-pmu.Add the remaining Xen sysfs nodes under /sys/hypervisor/ in a newfile Documentation/ABI/stable/sysfs-hypervisor-xen and add the Xenspecific sysfs docs to the MAINTAINERS file.Signed-off-by: Juergen Gross Reviewed-by: Boris Ostrovsky Signed-off-by: Juergen Gross List of files: /linux-6.15/Documentation/ABI/stable/sysfs-hypervisor-xen
