implement volume control in software via audio filter framework.
XXX: audio filter framework doesn't let me pass parameters from the hw
softc to the filter, so the volume variables are globals for now.
controls to match snapper
XXX - the gpios to monitor audio jacks are wired differently on different
Macs, this is known to work right on beige G3, PowerBook 3400 and Performa
63xx, it should do The Right Thing on others as well but needs more testing
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.
int _bus_dmatag_subregion(bus_dma_tag_t tag,
bus_addr_t min_addr,
bus_addr_t max_addr,
bus_dma_tag_t *newtag,
int flags)
void _bus_dmatag_destroy(bus_dma_tag_t tag)
that allow a (normally broken/limited) device to restrict the bus address
range it can talk to. this is used by bce(4) to limit DMA addresses to
1GB range, the maximum the chip can address.
all this is from Yorick Hardy <yhardy@uj.ac.za> with input from several
people on tech-kern.
XXX: bus_dma(9) needs an update still.
freaks out when a cardbus device is present.
enable with options PB3400_CARDBUS_HACK
- add a hack to make the DEC 21140 found on UMAX E100 cards work, for some
reason OF doesn't see it
enable with options UMAX_E100_HACK
writes they might issue to be delayed which keeps us from deadlocking
- don't splhigh() in cuda_intr() - usually we're there already. Instead do
the splhigh()/splx() dance when we're polling
- remove some leftover debugging gunk

To verify that no nasty side effects of duplicate includes (or their
removal) have an effect here, I've compiled an i386/ALL kernel with
and without the patch, and the only difference in the resulting .o
files was in shifted line numbers in some assert() calls.
The comparison of the .o files was based on the output of "objdump -D".
Thanks to martin@ for the input on testing.
by adding the "nargs" argument to the macppc version, and fix the macppc
ports uses of OF_interpret() accordingly.
Also move the declaration of OF_interpt() from macppc's autoconf.h to
ofw/openfirm.h. This fixes the build of the macppc port.
Approved by macallan@.
