to remove all xfers from the pending queue. It removes only xfers for
asynchronous transactions. So, simply loop over all pending xfers
with calling scsipi_done and wait xfers to drain. Addresses PR#9703.
that Charles added in rev 1.58. Not only is it good programming practice
to explain magic, but code that looks like:
reg = pcic_read(h, PCIC_IDENT);
reg = pcic_read(h, PCIC_IDENT);
is _gonna_ be interpreted as a cut-n-paste error by someone eventually.
FreeBSD umass driver by Nick Hibma <n_hibma@freebsd.org> and
MAEKAWA Masahide <bishop@rr.iij4u.or.jp>.
Improvements:
uses asynchronous USB requests
supports more transport protocols (Bulk-only and CBI)
supports more command sets (SCSI and ATAPI)
Tested with Zip100 and Imation Superdisk.
uvm_page_init() has completed, add a boolean uvm.page_init_done,
and test against that. Use this same boolean (rather than
pmap_initialized) in pmap_growkernel() to determine if we are
being called via uvm_page_init() to grow the kernel address space.
This fixes a problem on some i386 configurations where pmap_init()
itself was needing to have the kernel page table grown, and since
pmap_initialized was not yet set to TRUE, pmap_growkernel() was
choosing the wrong code path.
Fix tested by Havard Eidnes.
functions based on type returned from tga_getconf().
Adapt to change in ramdac interface.
Fix race condition in tga_sched_update().
Make tga_sched_update() work before interrupts are enabled.
if an IRQ was not detected, unless the force flag was given. Use this to
detect if the IRQ was for us (closer to shared IRQ for controllers which
don't have their own IRQ handler in pciide.c) and to poll for DMA xfer.
Also makes the timeout recovery code simpler.
- ATAPI cleanup: don't call controller-specific functions from atapiconf.c
(wdc_*), so that it's possible to attach an atapibus to something else
than a wdc/pciide (Hi Lennart :).
Overload struct scsi_adapter with struct atapi_adapter, defined
as struct scsi_adapter + atapi-specific callbacks. scsipi_link still points
to an scsi_adapter, atapi code casts it to atapi_adapter if needed.
Move atapi_softc to atapiconf.h so that it can be used by the underlying
controller code (e.g. atapi_wdc.c).
Add an atapi-specific callback *atapi_probedev(), which probe a drive
in a controller-specific way, allocate the sc_link and fills in the
ataparams if needed. It then calls atapi_probedev() (from atapiconf.c)
to do the generic initialisations and attach the device.
- While I'm there merge and centralise the state definitions in atavar.h.
It should now be possible to use a common ata/atapi routine to set the
drive's modes (will do later).
