[pkgsrc/trunk]: pkgsrc/sysutils Add Xen 4.11.0 packages.
details: https://anonhg.NetBSD.org/pkgsrc/rev/0eef9c50a386

description:
Add Xen 4.11.0 packages.
Note that there is a bug in 4.11 (also present in recent 4.6 and 4.8)
which causes an infrequent assert failure when running NetBSD PV guests.
The root cause has not been found, but a workaround is inclued which doesn't
seems to have ill effects. See xenkernel411/patches/patch-zz-bouyer
for details.

+Xen is a hypervisor which supports running multiple guest operating
+systems on a single machine. Guest OSes (also called "domains")
+can be either paravirtualised (i.e. make hypercalls in order to
+access hardware), run in HVM (Hardware Virtualisation Mode) where
+they will be presented with virtual devices, or a combination where
+they use hypercalls to access hardware but manage memory themselves.
+At boot, the xen kernel is loaded along with the guest kernel for
+the first domain (called domain0). domain0 has privileges to access
+the physical hardware (PCI and ISA devices), administrate other
+domains and provide virtual devices (disks and network) to other
+domains.
+
+This package contains the 4.8 Xen kernel itself. PCI passthrough is
+not supported. PAE is mandatory; on i386 one must use XEN3PAE_DOM[0U].

+The Xen hypervisor is installed under the following locations:
+ ${XENKERNELDIR}/xen.gz (standard hypervisor)
+ ${XENKERNELDIR}/xen-debug.gz (debug hypervisor)
+
+Note that unlike upstream Xen, pv-linear-pt defaults to true.
+You can disable it using pv-linear-pt=false on the Xen command line,
+but then you can't boot NetBSD in PV mode.

+x86: further avoid setting TLB flush time stamp
+
+NetBSD's use of linear page tables in 32-bit mode exposes an issue with
+us still storing TLB flush time stamps too early, corrupting the
+linear_pt_count field living in the same union. Since we go that path
+(for page tables) only when neither PGT_validated nor PGT_partial are
+set on a page, we don't really require a flush to happen (see also the
+code comment), yet we're also no concerned if one happens which isn't
+needed (which might occur when we never write the time stamp).
