Address kern/9370, kern/9548, kern/9571, and kern/9573.
Save and restore critical PCI configuration registers because they are
sometimes bashed.
Add a powerhook to restore said PCI registers after APM events.
The fxp now works across a warm boot from windows (vaio).
The fxp now works across an apm suspend/resume or hibernate/resume cycle.
is mapped in a way that is inaccessible by a 32-bit bus_addr_t, then
print a message to that effect and return failure.
Original patches by Bill Studenmund, with a few small changes by me.
- Use proper CARDBUS_* macro in if_rl_cardbus.c
- Use product ID read from PCI configuration space rather than from EEPROM
in if_rl_pci.c.
Patch sent from Masanori Kanaoka <kanaoka@ann.hi-ho.ne.jp> and
some cosmetic changes by me.
Fix minor glitches.
Add preliminary support for ASB-3940U3W host adapters; it might work w/ autotermination on.
ASB-3940U3W support is not yet tested due to lack of board.
- Call bus_dmamap_sync(9) as appropriate.
- Leave only register declarations in rtl81x9reg.h and
split other stuff into rtl81x9var.h.
bus_dma(9) code mostly taken from thorpej's if_rtp.c.
- Use le32toh() on reading rxstat from the Rx DMA buffer.
- rl_read_eeprom() should return EEPROM values in little endian
when caller requires byte-stream data.
bus_dma(9) fixes are still on-going.
XXX rtk on macppc seems to make tons of CRC errors...
XXX Does it work fine on i386 or others?
(the name 'siop' is still being discussed, may change).
Only basic disconnect/reselect for now, no sync/wide negotiation.
Tested with 810A, 875 and 895 on i386 only.
The bus-independant part should also be able to handle the 53c720 and 53c770.
A new driver with enhanced script should appear for the 825/875/895 'soon'.
Console text should now be supported on all TGA cards;
8- and 32-bit TGA and 8-bit TGA2 have been tested.
Implement accelerated character drawing, scrolling, and clearing.
Stop clearing "odd" in VHCR; it's unnecessary and hurts performance.
Use bus_space_vaddr() instead of a local hack.
to be called `rl' and it conflict with RL vax disks, canonical and
historical unix driver name.
This changes are minimal: it only changes the name of RealTek driver.
The filename of source code and a lot of the letter `rl' in source
files should be changed shortly.
cardbus_get_capability() [mirror change already made to if_tlp_pci.c]
- if_tlp_cardbus.c: If we don't find an ISV SROM, try to grab the
Ethernet address from the CIS.
- if_tlp_cardbus.c: set CardBus cards to store-and-forward mode from
the get-go.
- Put the TxThresh tables in tulipvar.h, and use them in the CardBus
and PCI front-ends to go to store-and-forward mode.
- Document the Xircom X3201-3 clone a little more.
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).
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.
The old timeout()/untimeout() API has been removed from the kernel.
2. Do not avoid ISA hole when a device requires more than
256-byte io space.
3. Remove sending CardBus bridge's function number to
cardbus stack. This number is not needed for anyone.
pci_config_dump variable to 1. otherwise, it gets set to 0. If
that's set, when configuring PCI devices spew the very verbose
configuration space header dump that was previously "#if 0"'d.
If you use this option, or patch the variable to 1, it's strongly
encouraged that you have used the MSGBUFSIZE option to enlarge the
kernel message buffer.
* QUIRK_NOMSG only has any meaning when NCR_GETCC_WITHMSG
is defined. Therefore, there's no harm in using it when
NCR_GETCC_WITHMSG is not defined. so, simplify the table
by removing the #ifdef.
* there's really no point in having table entries after
an entry which will match everything.
* add some comments, clean up spacing.
* add an entry for "QUANTUM"/"ATLAS IV" drives with flags
QUIRK_NOTAGS|QUIRK_NOMSG. (I included the latter flag only
because everything else had it before! ... which means that
all the functionality added with the NCR_GETCC_WITHMSG define
would never get used! *sigh*) The latter fixes the problems
I was having on an Atlas, and should fix the problems mentioned
by Hans Hoppe <hopha@casema.net> in comments on PR#7694.
1.4.x and i have concerns (but no concrete proof) they will cause/have caused
problems in -current as well. Really, the right way to fix this is to
rewrite the driver, and push up tagged queueing handling into a common
middle layer that'll do it right in a low-level-driver-independent manner.
I'll fix my particular issues by using the ncr driver quirk mechanism.
- fix a bug in ti_encap() where a NULL pointer could be used if we run out
of tx descriptors (return ENOMEM instead, and let the caller assert OACTIVE)
- sync boot messages with NetBSD's pci standart (print ti_name and irq
line)
- add a shutdown hook to stop the board, so that the board will not DMA at
random places while we're rebooting
- convert all but TIGON 1 transmit descriptors to use bus_space
(this last one isn't trivial to get rigth and I don't have the hardware to
test)
- If we can't map the mem space linar, retry to map it nolinear. Punt if
we couldn't map the mem space linear and we found a Tigon 1 chip.
With these changes a Tigon 2 board (netgear BA620 at last) can be used in
my DS20.
