2 daysusr: nerve: Add 'peek' verb to nerve(1)Ian Moffett
While poking at a nerve can be very useful, there are times where we need to peek at them to see their current state. This commit introduces the 'peek' verb to do exactly that. Here is how one may peek at the console features: -- [chloe::osmora]~ nerve peek consfeat ansi_esc=1 show_curs=1 -- Signed-off-by: Ian Moffett <ian@osmora.org>

2 daysusr: nerve: Convert nerve name in nerve_to_def()Ian Moffett
Add helper to convert nerve name into numeric nerve type so that peek_nerve() may be implemented while keeping things clean. Signed-off-by: Ian Moffett <ian@osmora.org>

The 'nerve' program allows users to poke at a ctlfs entry and write their own data. Signed-off-by: Ian Moffett <ian@osmora.org>
2 dayskernel/amd64: mp: Pin one idle thread to each coremainIan Moffett
Each core on the CPU gets one idle thread so that it is always up to something. To ensure these threads are not bouncing wildly between cores and are always ready for their respective processor to take when they have no threads to grab. We must call proc_pin() on each for every processor. Signed-off-by: Ian Moffett <ian@osmora.org>

2 dayskernel: sched: Add support for CPU pinningIan Moffett
This commit introduces support for pinning processes to specific cores which can be useful for things like, keeping core-specific workthreads running on their respective processors as well as mitigating very specific cases of false-sharing and performance degradation caused by a thread jumping between cores which requires cache-line entries to be thrashed around between them. Threads pinned to a specific core will always see their cached data in the same L1, L2, etc. Signed-off-by: Ian Moffett <ian@osmora.org>

3 dayskernel/amd64: Set up seperate syscall stackIan Moffett
It is a good idea to have a completely different stack during syscalls. This commit implements a TSS IST entry for syscalls. Signed-off-by: Ian Moffett <ian@osmora.org>

Signed-off-by: Ian Moffett <ian@osmora.org>
3 dayskernel: Sort out switch MI/MD switch logicIan Moffett
Certain operations dealing with context switches are better off being implemented as machine dependent routines which allows us to be flexible with what we can do, as well as the extra benefit of requiring less workarounds to keep things MI. Signed-off-by: Ian Moffett <ian@osmora.org>

3 dayskernel: proc: Decrement proc count on exitIan Moffett
Previously, our process counter was monotonic (wuh oh!). We want to be sure that it decrements when a process exits. - Rename nthreads to g_nthreads as a global - Atomically increment on enter and decrement on exit Signed-off-by: Ian Moffett <ian@osmora.org>
