cheloha [Fri, 14 May 2021 16:44:38 +0000 (16:44 +0000)]
amd64: specialreg.h: add MSR_TSC_ADJUST

Where available, the IA32_TSC_ADJUST MSR may be used to make race-free
relative adjustments to a logical CPU's TSC.  The value in the
register is interpreted as a signed 64-bit offset and added to the
"real" value of the TSC whenever the TSC MSR is read.  That is:

RDTSC = REAL_TSC + TSC_ADJUST

and:

RDMSR TSC = REAL_TSC + TSC_ADJUST

For example, if REAL_TSC=1 and TSC_ADJUST=1, then RDTSC would yield 2.
Or if REAL_TSC=10 and TSC_ADJUST=-5, then RDTSC would yield 5.

Writing TSC_ADJUST does not change the "real" underlying value of the
TSC.  Said another way setting TSC_ADJUST to zero will always undo any
prior adjustment.  This property may be useful in fixing desynchronized
TSCs.  In particular, buggy firmware may erroneously desynchronize a
normally synchronized TSC.  If this happens, in theory we can do:

wrmsr(MSR_TSC_ADJUST, 0);

and fix any desynchronization during boot/resume with no fuss.

3 years agoDo `so_rcv' cleanup with sblock() held.
mvs [Thu, 13 May 2021 19:43:11 +0000 (19:43 +0000)]
Do `so_rcv' cleanup with sblock() held.

solock() should be taken before sblock(). soreceive() grabs solock() and
then locks `so_rcv'. But later it releases solock() before call uimove(9).
So concurrent thread which performs soshutdown() could break sorecive()
loop. But `so_rcv' is still locked by sblock() so this soshutdown()
thread will sleep in sorflush() at sblock() call. soshutdown() thread
doesn't release solock() after sblock() call so it has no matter where to
release `so_rcv' - is will be locked until the solock() release.

That's why this strange looking code works fine. This sbunlock() movement
just after `so_rcv' cleanup  affects nothing but makes the code
consistent and clean to understand.
