auich_set_rate() modified audio_params::sample_rate to actual
sample rate though auich_set_params() rejected sample rates
other than some specific rates. For example, setting 8000Hz
with auich_set_params() modified sample_rate to 7998Hz in the
case of overclocked AC97 codec, and calling auich_set_params()
again returned with EINVAL because sample_rate was 7998Hz and
auich_set_params() rejected 7998Hz.
For now, auich_set_params() never modify audio_params::sample_rate.
and the back end Bluetooth device driver. The device driver now
allocates a suitable buffer on behalf of the bthci driver, and bthci
fills the buffer before despatch.
This saves an ugly temporary allocation (in bthci) and memory copy (in
the USB driver) per write, and also works better with the
sockets-based interface I'm experimenting with.
Uploaded scripts work better if they are little endian, as the
card's engine expects, so convert to le first.
Also clean up attach routine a bit (use pa_id and PCI_REVISION
instead of fetching it ourselves).
This makes the driver work on my macppc G4, it can decode and
display video and tuner input. Sound does not seem to work, but
this may be my wonky formac bktr-for-macintosh card.
unless ACPI_FDC_DEBUG
array returned from _FDE contains UINT32 values, not UINT8; also change
the magic number '14' to '5 * sizeof(UINT32)' for clarity
remove XXX for the tape presence comment; it's Just Okay to not use the info
fdc_acpi_getknownfds(): if fdc_acpi_nvtotype() returns NULL, don't
attempt to attach the drive at all
XXX not tested
which is safer than the loop there used to be here.
wi_mwrite_bap: if wi_write_bap fails, don't keep on going: this
way you avoid writing garbage to the radio. First time you see
an odd-length mbuf, copy the remainder of the chain to sc_txbuf
and from there to the MAC. This way, you do not read an mbuf past
the end of its data (occasionally you will cross a page doing
that!) and you avoid expensive, excess seeks in the radio's own
buffer chain.
wi_rx_intr: clamp the frame length told to us by the driver to the
most bytes we can fit in our mbuf cluster.
I am still getting e-mails from my testers telling me how much
better this makes things.
XXX - need to move this (as well as the equivalent sparc stuff added
recently) outa here into sbus_machdep or something. We should not need
to know details of the actual bus_space implementation here.
* Improve acpi interrupt fixup a bit
* Source is an array, don't compare it to NULL, instead
look for an empty string to denote a link-device-less
entry.
* For root PCI busses, try to use the _BBN method to get
numbering right.
* Add acpi_md_callback() function for MD handling after the init,
but before * at acpi probing.
