Søren Schmidt 8f0fb9584e Resurrect dump that broke with the last update. 2004-09-30 20:54:59 +00:00
Søren Schmidt b5dee91f5f Remove the old ATA_*LOCK_CH macros that used atomic ops and use 
mutexes instead.
This closes the last (known) race issues in ATA which should fix
the various hangs etc seen on heavy loaded systems.

Change from using timeout functions to using callout functions in
the timeout code. This together with above closes the race that could
happen if timeout and device interrupt occured simultaniously.

Also fix the possible recursion in ata_reinit() on very dodgy
devices that could take us down in the probe.

Søren Schmidt c5b2c44ce8 Rearrange the order of I/O's in dma-start/stop, some chipsets are very 
picky on the order of this, especially in error situations.

Søren Schmidt a49513587b Ignore leading '_' in model name returned by devices. 
This make "_NEC" devices appear as "NEC" which is more corrent.
The reason is tha NEC originally screwed up on the byteorder in the
model string, so now that they have realized that they prefixed the '_'
so that not every ATA driver on the planet would call them "EN C" :)

Søren Schmidt 1d535cd590 Reduce the amount of memory reported to busdma. 
This made the requirements for bouncebuffers too big with PAE.
Cleanup the way size defines for transfers are implemented.
 2004-09-10 10:31:37 +00:00
Søren Schmidt 6c893545ad Release the hold on ata_delayed_attach earlier so we can use tsleep 
in the boot probe as well.

Søren Schmidt 0f7cfb8473 Introduce ata_udelay() that uses tsleep instead of DELAY if possible. 
In places where we have long delays that doesn't depend on too accurate
timing, use ata_udelay() instead of DELAY() so we dont uselessly spin
the CPU if not nessesary;

Søren Schmidt dc26948b0c Fix the handling of "inflight" requests when doing reinit's. 
Add missing untimeout that would get lost in handling of some
error situations, and caused what looked like random timeouts
afterwards when the timeout fired.

Søren Schmidt 1c01d05f9c Sii_reset needs to wait up to 1 second to get slow disks with it so 
use tsleep instead of DELAY.

Søren Schmidt d04d789463 DONT PANIC 
Only call dmainit() if there is a valid busmaster resource.
 2004-08-20 06:19:25 +00:00
Søren Schmidt 5f7a48ef1e Improve (hopefully) on the workaround code for devices that doesn't 
interrupt when command is done, ie some ATAPI CD drives with no
media loaded.

Søren Schmidt fe76f7b6c8 Fix Promise sx4/sx4000 support that broke on the latest race fixes. 2004-08-16 09:29:46 +00:00
Søren Schmidt 8b68793ab3 Allow the use of a supplied function to set the PRD table. This is 
needed for new chips that supports 64bit addressing.
 2004-08-13 08:14:27 +00:00
Søren Schmidt d53fc3e41c Change the order of ata_dmainit/ata_allocate in preparation of 
supporting new chipsets where this is needed.

Nate Lawson c68afc9d21 Fix a panic in ata_generic_transaction(). The DMA pointer of the channel 
was being unconditionally dereferenced but was NULL for PIO requests.
Check the request flags for a DMA transaction before dereferencing.

Søren Schmidt b4d89b2e0f Fix the reset sequence for sx4/sx4000 type controllers, it could hang the 
chip in an indefinite state.

Søren Schmidt a4c3e742b7 Refine the wait for ATAPI_RESET. 
Properly wait for not busy and introduce a timeout for devices not
setting busy (as they should).
Leave a printf in there that states how long the wait was, as I'd like
to get an idea of the variations here. The time needed seems also to be
affected by whether a medium is present or not.

Brian Feldman 5fd2bb173d Call the detach function with g_waitfor_event() so that it can access 
the GEOM topology.

There are still issues with not detaching from cam correctly such that
upon a device detach there's an invalid pointer dereference from the
later call to cam_rescan().

Søren Schmidt b2c082c98b Up SiI reset wait a bit, some devices got lost. 2004-06-17 21:36:10 +00:00
Brian Feldman 3c632a5847 atapicam(4) is currently off by three orders of magnitude regarding the 
timeout values in the CAM CCBs.  Divide by 1000 to get values in seconds
which are what ata(4) timeouts internally use.

This does lose granularity, though, and small values can now round down
to zero.  It's probably worth making all ata(4) timeouts in terms of
hz/ticks/milliseconds/something.
