through the interrupt pipe; during exploration check only the ports
where we got such a notification. This speeds up things.
(I believe we should go a step further and use a thread per hub
instead of per bus. If power management gets implemented, we should
be able to react quickly on a resume event.)
Try to simplify the logics in the explore function a bit. (The reattach
thing was hacked in badly, not sure whether I broke it. Only used
by if_atu.)
Clean up some dead code.
(Thermal Monitor).
This driver will throttle the CPU clock modulation, saving some
power, also known as ODMC (On Demand Modulation Clock).
The processor can change from 12.5% to 100% (there are two erratas,
so two levels might be skipped in the worst case).
If supported, you'll see the following sysctl sub-tree:
machdep.p4tcc.throttling.target: CPU Clock throttling state (0 = lowest, 7 highest)
machdep.p4tcc.throttling.current: current CPU throttling state
machdep.p4tcc.throttling.available: list of CPU Clock throttling states
machdep.p4tcc.throttling.target = 2
machdep.p4tcc.throttling.current = 2
machdep.p4tcc.throttling.available = 7 6 5 4 3 2

so it's not worth counting.
- lwp_wakeup: set LW_UNPARKED on the target. Ensures that _lwp_park will
always be awoken even if another system call eats the wakeup, e.g. as a
result of an intervening signal. To deal with this correctly for other
system calls will require a different approach.
- _lwp_unpark, _lwp_unpark_all: use setrunnable if the LWP is not parked
on the same sync queue: (1) simplifies the code a bit as there no point
doing anything special for this case (2) makes it possible for p_smutex
to be replaced by p_mutex and (3) restores the guarantee that the 'hint'
argument really is just a hint.
cpp macros and long src operands anyway that destroy any intended
"neatly lined up" effect that TAB was supposed to achieve.
White space change only, same object code is generated, but it is much
easier on the eyes now.
emits for sh4 to copy 12 bytes at certain optimization levels.
Discovered by compiling landisk kernel with -Os.
Use gcc3 naming ("movstr") to match the rest of the "movstr" files.
pool_init() is supposed to do, and actual usage of that argument in
pool_init()'s implementation, add use of IPL_VM to the TLB shootdown
job queue pool initialization to get this building again.
Someone suggested an IPL_XXX_ASK_ANDY constant be introduced...
locators for uhub because a hub can't have sub-devices.
This might be sanity-checked eventually.
Same for ubt now after the change to device attachment.
- add dummy input mixer controls
- restart tx DMA on PWR_RESUME
- power up on PWR_RESUME only if we really have to
- add an option to control wether to spin or sleep when waiting for the chip
to switch between data and control mode
- pass WARNS=4 and lint
- use size_t/time_t where appropriate
- get/setprogname()
- before executing rc.shutdown, set the real user id to 0, because shutdown
scripts may depend on it (for example su depends on being root).
- use warn instead of perror, and make sure we use the right errno.
