* Added B_ prefix.
* Renamed 16 bit variants to B_LENDIAN16_*.
* Added 32 bit variants (albeit only 16 of them for now).
* Adjusted headers that were using them.
* Move to more standardized functions matching AHCI spec
* Don't perform unnecessary double port resets
* Begin implementing a software reset to try first per spec.
Software reset needs more work, falls through to port reset
for the moment which is stable.
* Don't duplicate ATA defines, use what we already provide.
* Tested working on VirtualBox 1-16 AHCI ports, Intel C200,
and AMD FCH.
* The UNMAP command is theoretically much faster, as it can get many block
ranges instead of just a single range.
* Furthermore, the ATA TRIM command resembles it much better.
* Therefore, fs_trim_data now gets an array of ranges, and we use SCSI UNMAP
to trim.
* Updated BFS code to collect array ranges to fully support the new
fs_trim_data possibilities.
* imported asc-num.txt as a reference, was used to generate the asc sense table.
* use the sense asc and key tables to know which action and status codes are
to be applied.
* tested with an hard disk and a dvd reader.
* these tables could be reused by the scsi_periph module.
* The default module is replaced by the Virtio RNG module when found.
* This can have the undesired effect of rendering /dev/urandom slow.
* Tested with the following QEmu command line option:
-device virtio-rng-pci,rng=rng0 -object rng-random,filename=/dev/random,id=rng0
* moved random.h to private/drivers headers.
* added support READ_12/16 and WRITE_12/16 in ata and scsi_periph, this enables read/write on block offsets greater than 2TB

* ata: don't fail if lba_sector_count is null and lba48_sector_count is not
* scsi_periph: if ReadCapacity() returns 0xffffffff, use ReadCapacity16() instead
* scsi_disk: use a different computation in the struct geometry computation for bigger disks
Tested successfully with a virtual 10TB hard drive.

Define structs for iSCSI messages, to be used by boot loader and kernel add-on.
For now it will refuse to compile for Little Endian systems (e.g., x86).

Based on a SCSI Command Reference Manual by Seagate and Wikipedia.
Tested against OpenSolaris iSCSI target on ppc. It choked on the READ (12) opcode.

* Internally, moved the contents of periph_io() into a static read_write()
function, and use it from the new periph_read_write() as well.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@36988 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Copied ide_adapter.h as ata_adapter.h in attempt to further
separate the two stacks.
* Continued renaming stuff in drivers/bus/ATA.h
* Make all the busses/ata drivers include the new headers,
specifically ata_types.h, ata_adapter.h and bus/ATA.h,
they were all including ide_types and bus/IDE.h still
* Some renaming of global variables for coding style consistency
* Removed the promise driver from the build, it's not used on the
image and I don't believe it compiled even for the old IDE stack.
* There is no more Command Queueing in the new ATA stack, so I
removed the capability indication from the busses/ata drivers
and ata_adapter.h.
The new ATA stack still boots fine on my computer and I proof-read
the diff like two times. Basically, this was a careful search&replace
job only. The only things I am not sure about is renaming some
publishing related strings, but it seems to all work fine.

* Reworked some of the transfer handling after reading the specs.
* Ensure that the device selection bit is set correctly for all commands.
* Generally disable interrupts and enable them only when expecting a DMA one.
* Renamed disk failure to device fault according to specs.

but doesn't really do anything more than before.
* It also replaces everything IDE with ATA counterparts and cleans up a lot
of the definitions.
* Cleaning up the old ATA bus_manager as well as some license headers missing.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30049 a95241bf-73f2-0310-859d-f6bbb57e9c96
ide_mask_sector_count_48, and ide_mask_LBA_*_48 were all wrong.
* Using the high byte in LBA48 mode should work now, too (wasn't written
to the IDE controller before, but that shouldn't have been a problem yet with
today's disks).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@28340 a95241bf-73f2-0310-859d-f6bbb57e9c96
our dma_restrictions structure (but we're using blocks instead of bytes,
since unlike the block size, the restrictions attributes are constant).
* We might want to use blocks for the dma_restrictions structure as well in
the future...
* Fixed another bug in the device_node variant of DMAResource::Init(): the max
segment size was specified in blocks as well.
* Removed the "hardcode" block_io module and header.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26973 a95241bf-73f2-0310-859d-f6bbb57e9c96
architecture: for now, we do this on the lowest layer only, therefore all
requests are handled synchronously (ie. in the scheduler's thread).
* Instead of using the block_io module, scsi_disk (and scsi_cd) are now
exporting a device on their own, and use an I/O scheduler with an appropriate
DMA resource.
* There are still lots of TODOs, and it can easily panic - don't update if
you intend to demo Haiku.
* scsi_periph now only has an io() function that get an io_operation, instead
of the previous read/write functions, moved preferred CCB size from those
functions into the device registration.
* Changed all scsi_periph files to C++.
* scsi_cd ported, too, but untested.
* Removed block_io from image - it will be removed completely soon.
* Temporarily commented an ASSERT() in the ATA bus manager (in case you use
it); it's sometimes triggered by the code now, and I haven't yet looked into
the issue -- doesn't seem to harm, at least.
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@26828 a95241bf-73f2-0310-859d-f6bbb57e9c96
* Moved devfs from fs/ to device_manager/, and separated the legacy driver
support from it.
* Removed fast_log module.
* There are a couple of (temporary) regressions, though:
- legacy SATA and ISA IDE support is disabled, the drivers haven't been
ported yet.
- The not yet used ATA bus manager hasn't been ported yet, either.
- AHCI changes have not been tested.
- the listdev command has been removed from the build (as it currently
doesn't work anymore).
- device manager generated IDs currently are not freed anymore when a device
node is removed.
- generic drivers can't yet use the new driver architecture.
- simple busses that do not support device types won't work yet.
- legacy driver publishing/unpublishing (ie. what USB needs) has not been
tested, and may be broken.

again.
* Publish /dev/ptmx. Opening it will open a fresh pty master. In
principle /dev/pt/ is obsolete now, but I guess we keep it around for
compatibility with BeOS. Though there shouldn't be many applications
opening a pty, that we might be interested in...
* New ioctls B_IOCTL_GET_TTY_INDEX (returns the tty index) and
B_IOCTL_GRANT_TTY (grants tty slave access rights).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25133 a95241bf-73f2-0310-859d-f6bbb57e9c96
Replaced IDE_ADAPTER_IS_PRIMARY by IDE_ADAPTER_CHANNEL_INDEX to support more than 2 bus master channels,
and made ide_adapter aware of 3rd and 4th channel when calculating bus master dma address.
Fixed bus master DMA support in legacy_sata driver for tertiary and quaternary channel, channel 3 and 4
were using the DMA engine of primary and secondary channels (that might have destroyed your data).
Use PCI_address_io_mask instead of ~PCI_address_space (no functional change).
git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@23207 a95241bf-73f2-0310-859d-f6bbb57e9c96
actually forgot to commit the changes I made to the ide_adapter...
* the IDE bus master command/status stuff is now used via flags; it's no
bitfield anymore.
* Changed a few constants to upper case.
