Pyun YongHyeon e79b243289 Export sysctl node for various interrupt moderation parameters and 
have administrators control them.  ti(4) provides a character
device to control various other features of driver via ioctls but
users had to write their own code to manipulate these parameters.
It seems some default values for these parameters are not optimal
on today's system but leave it as it was and let administrators
change them.  The following parameters could be changed:

dev.ti.%d.rx_coal_ticks
dev.ti.%d.rx_max_coal_bds
dev.ti.%d.tx_coal_ticks
dev.ti.%d.tx_max_coal_bds
dev.ti.%d.tx_buf_ratio
dev.ti.%d.stat_ticks

The interface has to be brought down and up again before a change
takes effect.

ti(4) controller supports hardware MAC counters with additional
DMA statistics.  So it's doable to export these counters via
sysctl interface.  Unfortunately, these counters are cumulative
such that driver have to either send an explicit clear command to
controller after extracting them or have to maintain internal
counters to get actual changes.  Neither look good to me so
counters were not exported via sysctl.

amd64 Fix SIGATOMIC_M{IN,AX} on x86-64. These are meant to be the minimum values that are allowed in a sig_atomic_t, but it looks like they were just copied from the x86 versions, so these definitions violate the C and C++ specs. Mismatch was spotted by the libc++ test suite. 2011-11-12 20:16:06 +00:00
