Hi,
The last part of IDE changes for 2.6.31 merge window:
* Fix ide-cd OOPSing on failed commands. (Rainer Weikusat)
* IORDY handling fixes.
* Sanitize methods for IRQ clearing/testing. (Sergei Shtylyov)
* ATAPI support update. (Borislav Petkov)
* Misc fixes/cleanups.
Linus, please pull from 'for-2.6.31' branch of:
master.kernel.org:/pub/scm/linux/kernel/git/bart/ide-2.6.git for-2.6.31
to receive the following updates:

Hi,
Part 3, some interesting stuff this time:
- ide-atapi: build fix for non-x86 archs (Geert Uytterhoeven)
- ide-cd: regression fix, start DMA after issuing a packet command
(Borislav Petkov)
- ide-park: regressing fix, correct handling of sleeping devices
(Elias Oltmanns)
- ide-pmac: cable detection fix for Apple PowerBook (TOMARI Hisanobu)
and fix allowing modular IDE build (Gilles Espinasse)
- ide-{floppy,tape}: bug fix for padding of PIO transfers
- support for CompactFlash specific transfer modes (Sergei Shtylyov)
- struct ide_tp_ops sanitizations (Sergei Shtylyov)
- ide-cd: conversion to use scatterlists also for PIO transfers
- many other fixes/cleanups, detailed changelog below

0 siblings, 0 replies; 3+ messages in thread
From: Bartlomiej Zolnierkiewicz @ 2009-01-06 17:12 UTC (permalink / raw)
To: Linus Torvalds; +Cc: Andrew Morton, Stephen Rothwell, linux-ide, linux-kernel
Part three:
* Resurrect IT8172 IDE host driver.
(from Shane McDonald)
* Fix 32-bit I/O support for ATA-8 and ATA-1 devices.
(from Mario Schwalbe)
* Switch ide-cd over generic ATAPI support.
(from Borislav Petkov)
* New locking scheme (which is both simpler and more efficient) for hosts
with serialized ports and related cleanups.
* struct ide_dma_ops sanitization and related cleanups.
(from Sergei Shtylyov)
* Misc fixups/cleanups...
This should be the final part of IDE updates for 2.6.29 merge window
(I would like to thank all contributors!).
Linus, please pull from:
master.kernel.org:/pub/scm/linux/kernel/git/bart/ide-2.6.git/

- * Issue a new request to a drive from hwgroup
- *
- * A hwgroup is a serialized group of IDE interfaces. Usually there is
- * exactly one hwif (interface) per hwgroup, but buggy controllers (eg. CMD640)
- * may have both interfaces in a single hwgroup to "serialize" access.
- * Or possibly multiple ISA interfaces can share a common IRQ by being grouped
- * together into one hwgroup for serialized access.
- *
- * Note also that several hwgroups can end up sharing a single IRQ,
- * possibly along with many other devices. This is especially common in
- * PCI-based systems with off-board IDE controller cards.
- *
- * The IDE driver uses a per-hwgroup lock to protect the hwgroup->busy flag.
- *
- * The first thread into the driver for a particular hwgroup sets the
- * hwgroup->busy flag to indicate that this hwgroup is now active,
- * and then initiates processing of the top request from the request queue.
- *
- * Other threads attempting entry notice the busy setting, and will simply
- * queue their new requests and exit immediately. Note that hwgroup->busy
- * remains set even when the driver is merely awaiting the next interrupt.
- * Thus, the meaning is "this hwgroup is busy processing a request".
- *
- * When processing of a request completes, the completing thread or IRQ-handler
- * will start the next request from the queue. If no more work remains,
- * the driver will clear the hwgroup->busy flag and exit.
- *
- * The per-hwgroup spinlock is used to protect all access to the
- * hwgroup->busy flag, but is otherwise not needed for most processing in
- * the driver. This makes the driver much more friendlier to shared IRQs
- * than previous designs, while remaining 100% (?) SMP safe and capable.
