which relied on taking extra vnode refs.
Having benchmarked various experimental changes over the past few months it
seems that it's better to avoid vnode refs as much as possible. cwdi_lock
as a RW lock already did that to some extent for getcwd() and will permit
the same for namei() too.
arg are separate arguments - this is needed for newer physdev_op commands
remove code for PHYSDEVOP_IRQ_UNMASK_NOTIFY, it is obsolete since
interface version 0x00030202 and is unsupported by newer versions of Xen
confirmed working on amd64 Dom0, i386 compile-tested only
up to MAXPHYS (implementation limit, interface allows more) using
single request
request using indirect segment requires 1 extra copy hypercall per
request, but saves 2 shared memory hypercalls (map_grant/unmap_grant),
so should be net performance boost due to less TLB flushing
this also effectively doubles disk queue size for xbd(4)
* Control sockets are not opened in test mode
* privsep: no longer aborts if protocol not available
* inet6: Don't regen temporary addresses without a state
* inet6: Reduce RA log spam
* dhcp6: Don't log when things consitently fail
* inet6: Add temporary directive to slaac option [1]
* Ensure current interface flags persist when setting a flag
* DHCP via BPF is now aligned correctly
* CMSG buffers are now aligned correctly
* hostnames are no longer clobbered when being forced and a RA is recieved
[1] dhcpcd no longer looks at any possible kernel settings when deciding to
manage IPv6 temporary addresses or not. You now instruct dhcpcd to do this
in dhcpcd.conf. Playing whack-a-mole with various kernel knobs wasn't fun
and some OS's have or are removing RA and thus temporary address managemnt
from the kernel so said knobs are no longer there.
- If the max CPUID leaf is >= 0x15, take TSC value from CPUID. Some processors
can take TSC/core crystal clock ratio but core crystal clock frequency
can't be taken. Intel SDM give us the values for some processors.
- It also required to change lapic_per_second to make LAPIC timer correctly.
- Add new file x86/x86/identcpu_subr.c to share common subroutines between
kernel and userland. Some code in x86/x86/identcpu.c and cpuctl/arch/i386.c
will be moved to this file in future.
- Add comment to clarify.
entry last. correct the sizeof() to use the right variable
(they were the same size at least.) as-was, with the NULL
entry first, all loops across this array were no-ops.
this should fix PR#55158's arm64 side.
Bad news:
* grant table v2 is not supported for HVM guests on 4.11 at last.
* see xen/arch/x86/hvm/hypercall.c in Xen sources (missing
* GNTTABOP_get_status_frames)
So restore grant table v1 for !XENPV
