traversal code to suspend/resume
ok oga kettenis blambert
|
|
We call the activate functions at splhigh; unfortunately we cannot suspend a
zaurus at splhigh because on resume the clock is hosed. We accept this bug
for now... perhaps someone can find it?
(The powerhooks remain in place in the drivers, and will be roto-tilled once
we all the other powerhook-using architectures have switched over)
testing by myself and jakemsr; proof reading by oga

Of note: lcd stubs get pulled up to the parent; zts has to keep track of
whether it is in use or not

which contains the constraints for DMA/memory allocation for each
architecture, and dma_constraints which contains the range of addresses
that are dma accessable by the system.
This is based on ariane@'s physcontig diff, with lots of bugfixes and
additions the following additions by my self:
Introduce a new function pool_set_constraints() which sets the address
range for which we allocate pages for the pool from, this is now used
for the mbuf/mbuf cluster pools to keep them dma accessible.
The !direct archs no longer stuff pages into the kernel object in
uvm_km_getpage_pla but rather do a pmap_extract() in uvm_km_putpages.
Tested heavily by my self on i386, amd64 and sparc64. Some tests on
alpha and SGI.

When we hit suspend time, go through all wsdisplays on the system. if
they are in mode MAPPED, but not MODE_DUMBFB then if possible do a full
vt switch to a !mapped vt, and prevent switching back until resume time.
This has to be called from MD code because this involves userland
running so that X can run the vt switch signal handler. This way, any
case where we are using the "poke registers from userland" model, we
will not be on the hardware when we go down, so the kernel can actually
handle thing properly.
Tested on several acpi laptops (by kettenis@ and ian@), x40 (me and
beck@ at LEAST) and zaurus (me). Maybe others, but if so I forgot who at
this time..

uvm_km_alloc() (which allocates some virtual space and then
$size_of_mapping pages which it then enters) *then* pmap_kenter the
bus_space address that we wish to map, it's just a little bit stupid and
a waste of memory.
replace with uvm_km_valloc and ponies for everyone.

remove it from any occurences where both are used, except one for kqueue itself
and one in sys_pipe.c (where the selwakeup is under a PIPE_SEL flag).

always return zero.

first instead of trying to push data transfers forward. Also, ensure that
DONE interrupts are only un-masked when we are on the last sub-block, and
that otherwise we process based on RD_REQ and WR_REQ interrupts coming in.
Done with drahn and marex (starting from bizzare workarounds by marex
which we could not explain)
This appears to make Zaurus SD reads & writes completely reliable, even at
very low cpu speeds.
