fb9e02fbd8 Clean up AC97 driver for merge 2015-05-13 15:26:28 -07:00
Mike Gerow
3b60e8c36f Added experimental ac97 driver. 
This doesn't include a userland interface, but it does include a couple
of commands for the debug shell. ac97_status, which shows some register
and port values for the ac97 and ac97_noise which attempts to play a
(very annoying) 440Hz sine wave through the sound card.

7344a50fe0 Major changes to timing interfaces 
- The kernel version has been bumped to 0.9.0
- The timer resolution in the kernel has been increased to millseconds.
- The preemptive scheduling interval has been descreased to one
  millisecond.
- Relative sleep continues to use 10 millsecond intervals for legacy
  reasons.
- `gettimeofday` now uses the internal tick counter to calculate the
  current time. Drift is calculated from the CMOS every 5 seconds and
  applies only to `gettimeofday` and other places that use it.
- The resolution of timing information provided by debug functions has
  been increased to three digits (milliseconds).
- The resolution of timing information provided by the procfs uptime
  virtual file has been increased to three digits (milliseconds).
- Functions have been added to the debug shell to read the TSC. The TSC
  is not used in timing functions at this time.

4d8335ad75 Implement proper wait/waitpid. 
This is a pretty big commit, so let's run through it in parts:

- All of the userspace changes are to switch away from syscall_wait
  Mostly, this is to waitpid; some things were tweaked to do things
  "properly" instead of waiting for particular processes. Init has
  been fixed to do a proper spin wait.
- syscall_wait is gone - as are its uses. newlib bindings have been
  using just waitpid for a while now.
- waitpid now performs like a Unix waitpid
- process reaping is no longer a "do this on next change thing":
  it happens when a process is waited on, like it should
  (That means we can have real zombies: terminated processes that
  have not yet been waited on)
- Reparenting of children to init has been implemented, so you
  can fork-daemonize!

Overall, this is pretty big... So I hope it doesn't break everything.

cc4391d783 Initial work on modules 
There's a lot here, so let's through it:
- Lots of work to include a symbol table in the kernel. We can't rely on
  our bootloader to give us our own ELF information, so we do this
  separately. This probably should be changed to output a C source
  rather than assembly, but that's a TODO.
- Makefile can now generate modules. It works basically the same way any
  other kernel object works, expect with a slightly different linking
  scheme.
- Commands have been added to the debug shell to load modules, but they
  don't work yet - still need to get through relocation and linking.
- Commands have been added to the debug shell to print the symbol list,
  as well as print symbol values (but note that printing symbol values
  is kinda dangerous if you don't know what they are, so don't just go
  printing things willy-nilly).
