altq Drop Type
disklabel Disk Type
file Descriptor Type
(not to mention constants that contain the string DTYPE).
Let's make them two, by changing the disklabel one to be DisK TYPE since the
other disklabel constants seem to do that. Not many userland programs use
these constants (and the ones that they do are mostly in ifdefs). They will
be fixed shortly.
to the disk subsystem.
Make disk_set_info also set blocksize shift values.
Remove every call to disk_blocksize.
Keep disk_blocksize for ABI compatibility, make it also set dg_secsize.
scsi 3 inquiry command than expected by the size of the scsi 3 inquiry
packet. This can be detected by looking at the additional_length field
returned by the scsi 2 inquiry. If that's the case, avoid doing the
scsi 3 inquiry because we can't handle the extra bytes later.
XXX: Pullup -7
designated initializers.
I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.
soft interrupt driven operation.
Add a polling mode of operation -- now we can ask hardware random number
generators to top us up just when we need it (bcm2835_rng and amdpm
converted as examples).
Fix a stall noticed with repeated reads from /dev/random while testing.
clamp it to 256 (maximum number of tags in SCSI). Newer controllers
(such as mpii(4), and mfi(4) when fixed to announce tagged queuing support)
support more than 256 outstanding commands and don't use the scsi tag,
but at this time scsipi will always allocate a tag, and panic if a periph
tries to send more than 256 commands.
ATA drives to not be detected when the PATA (or emulated PATA) bus is shared
with an ATAPI device.
Should fix the problem reported by various peoples.
Thanks to Onno van der Linden and vanoven@free.fr for pointing out the
code in error.
Sun, 15 Jul 2012 10:56:50 +0000, excepting the kernel version bump.
First step in reverting regressions to ata(4) subsystem during the addition of
port multiplier support.
Prefix the DRIVE_ and DRIVET_ constants from atavar.h with ATA_.
Don't use an enum for drive_type - you don't know how big it will be.
Move driver_type to avoid implicit structure padding (esp on arm).
This change is purely lexical and mechanical.
Update to 6.99.9 - this wasn't done when the SATA PMP changes
were made - I'm sure they warranted a bump.
as described in
http://mail-index.netbsd.org/tech-kern/2012/06/23/msg013442.html
PMP support in integrated to the atabus layer.
struct ata_channel's ch_drive[] is not dynamically allocated, and ch_ndrive
(renamed to ch_ndrives) closely reflects the size of the ch_drive[] array.
Add helper functions atabus_alloc_drives() and atabus_free_drives()
to manage ch_drive[]/ch_ndrives.
Add wdc_maxdrives to struct wdc_softc so that bus front-end can specify
how much drive they really support (master/slave or single).
ata_reset_drive() callback gains a uint32_t *sigp argument which,
when not NULL, will contain the signature of the device being reset.
While there, some cosmetic changes:
- added a drive_type enum to ata_drive_datas, and stop encoding the
probed drive type in drive_flags (we were out of drive flags anyway).
- rename DRIVE_ATAPIST to DRIVE_ATAPIDSCW to better reflect what this
really is
- remove ata_channel->ata_drives, it's redundant with the pointer in
ata_drive_datas
- factor out the interpretation of SATA signatures in sata_interpet_sig()
propagate these changes to the ATA HBA drivers, and add support for PMP
to ahcisata(4) and siisata(4).
Thanks to:
- Protocase (http://www.protocase.com/) which provided a system
with lots of controllers, SATA PMP and drive slots
- Conservation Genomics Laboratory, Department of Biology, New Mexico State
University for hosting the above system
- Brook Milligan, who set up remote access and has been very responsive
when SATA cable move was needed
requiring a message, we will most likely get that from the spinup attempt
anyway.
This avoids the spurious "Check Condition on CDB, Not Ready, Medium Not
Present, Tray Closed" messages at boot/shutdown time.
