syncer_thread: sleep without lbolt The syncer_thread() uses lbolt to perform periodic execution. We can do this without lbolt. - Adding a local wakeup(9) channel (syncer_chan) and sleep on it. - Use a local copy of getnsecuptime() to get 1/hz resolution for time measurements. This is much better than using gettime(9), which is wholly unsuitable for this use case. Measure how long we spend in the loop and use this to calculate how long to sleep until the next execution. NB: getnsecuptime() is probably ready to be moved to kern_tc.c and documented. - Using the system uptime instead of the UTC time avoids issues with time jumps. ok mpi@ |

Some BIOS seem to provide memory regions <16M in their reserved memory region reporting table. Since the extent only covered memory starting at 16M, these regions could not be reserved and would in turn cause a panic. Make the extent start at 0 and immediately reserve the first 16M right away, so that we can change the reserved memory allocator to EX_CONFLICTOK to make allocations succeed if they are already reserved. ok kettenis@ |
