9What: PRISM54
10When: 2.6.34
11
12Why: prism54 FullMAC PCI / Cardbus devices used to be supported only by the
13 prism54 wireless driver. After Intersil stopped selling these
14 devices in preference for the newer more flexible SoftMAC devices
15 a SoftMAC device driver was required and prism54 did not support
16 them. The p54pci driver now exists and has been present in the kernel for
17 a while. This driver supports both SoftMAC devices and FullMAC devices.
18 The main difference between these devices was the amount of memory which
19 could be used for the firmware. The SoftMAC devices support a smaller
20 amount of memory. Because of this the SoftMAC firmware fits into FullMAC
21 devices's memory. p54pci supports not only PCI / Cardbus but also USB
22 and SPI. Since p54pci supports all devices prism54 supports
23 you will have a conflict. I'm not quite sure how distributions are
24 handling this conflict right now. prism54 was kept around due to
25 claims users may experience issues when using the SoftMAC driver.
26 Time has passed users have not reported issues. If you use prism54
27 and for whatever reason you cannot use p54pci please let us know!

209What: libata spindown skipping and warning
210When: Dec 2008
211Why: Some halt(8) implementations synchronize caches for and spin
212 down libata disks because libata didn't use to spin down disk on
213 system halt (only synchronized caches).
214 Spin down on system halt is now implemented. sysfs node
215 /sys/class/scsi_disk/h:c:i:l/manage_start_stop is present if
216 spin down support is available.
217 Because issuing spin down command to an already spun down disk
218 makes some disks spin up just to spin down again, libata tracks
219 device spindown status to skip the extra spindown command and
220 warn about it.
221 This is to give userspace tools the time to get updated and will
222 be removed after userspace is reasonably updated.

451What: sound-slot/service-* module aliases and related clutters in
452 sound/sound_core.c
453When: August 2010
454Why: OSS sound_core grabs all legacy minors (0-255) of SOUND_MAJOR
455 (14) and requests modules using custom sound-slot/service-*
456 module aliases. The only benefit of doing this is allowing
457 use of custom module aliases which might as well be considered
458 a bug at this point. This preemptive claiming prevents
459 alternative OSS implementations.
460
461 Till the feature is removed, the kernel will be requesting
462 both sound-slot/service-* and the standard char-major-* module
463 aliases and allow turning off the pre-claiming selectively via
464 CONFIG_SOUND_OSS_CORE_PRECLAIM and soundcore.preclaim_oss
465 kernel parameter.
466
467 After the transition phase is complete, both the custom module
468 aliases and switches to disable it will go away. This removal
469 will also allow making ALSA OSS emulation independent of
470 sound_core. The dependency will be broken then too.
