2006-12-12small cleanup after feng shuiDavid Gwynne
2006-12-12Give the SCSI layer the ability to requeue i/o's rejected by a driverKenneth R Westerback
using the new NO_CCB result. Currently a no-op since no driver produces that result. ok dlg@ marco@ deraadt@
2006-12-12after allocating the ahci_port bits, stash it in the softc rather thanDavid Gwynne
drop it. im guessing at some point we'll want to use each port, knowing where they are can help.
2006-12-12feng shuiDavid Gwynne
2006-12-12for each port the controller says is hooked up, go and allocate ourDavid Gwynne
ahci_port structs for it.
2006-12-12start implementing the bits that allocate the per port structures and theirDavid Gwynne
ccb lists. this is missing handling of the dmamem each port needs to manage, but that can wait till i figure out how it fits together. insane stuff.
2006-12-12remember our dma tag. be able to do dma is like, really cool. man.David Gwynne
2006-12-12add functions to get and put ccbs out of each ports command free list.David Gwynne
2006-12-12add wrappers for reading and writing a ports registers called ahci_pread,David Gwynne
and ahci_pwrite. these will use an io handle into a window of the controllers register space that can be created with bus_space_subregion, and which is stored in the ahci_port struct.
2006-12-12introduce the command control blocks, and the concept that they are managedDavid Gwynne
per port rather than as a big list for the whole controller. the softc has an array of pointers to a struct that manages all the shizz relevant to a particular port. when we map the controllers ports, we'll allocate these as needed. if the port isnt implemented, we leave its pointer in the softc null and use that to decide if a drive might be there or not, rather than lookup up the PI register all the time. a comparison has to null has to be cheaper than doing bit operations, surely.
2006-12-12stash the number of commands each port can do in the softcDavid Gwynne
2006-12-11Ensure kvm86_call actually saves the curpcb instead of junk. ErrorGordon Willem Klok
introduced by myself at h2k6, thanks mickey@ and toby@ for turning me in the direction of a corrupt PCB.
2006-12-11use oct bits consistently in the format string for %b. pointed out byDavid Gwynne
deraadt@
2006-12-11refer to the RSTP point to point option as "PTP" instead of "P2P".Reyk Floeter
P2P is commonly used in relation to peer to peer networks, PTP is used in various protocols for layer 2 point to point links (ie., full duplex ethernet links). note that the newly added brconfig commands [-]p2p and [-]autop2p will change to [-]ptp and [-]autoptp. suggested by Andrew Thompson (thompsa@freebsd.org)
2006-12-11allow RST with th_seq incremented (seen from windows tcp clients); ok dhartmeiMarkus Friedl
2006-12-11do not bus_space_map devices which are at address 0; ok kettenisTheo de Raadt
2006-12-11change sig_atomic_t to int (was long). spotted by Alexander_Bluhm@genua.deTheo de Raadt
this is a tiny ABI change, but it is better for a handfull of reasons

2006-12-11oops, we want to return when everything goes well in ahci_attach, ratherDavid Gwynne
than fall through to the bits that do cleanup when an error occurs.
2006-12-11remove the argument to all the port registers that say which port you wantDavid Gwynne
to address. instead make them simply offsets from the start of a ports register space, which is something we can easily set up with bus_space_subregion. this should make the code a lot easier to read later on.
2006-12-11dont stash the implemented ports map, im going to use a differentDavid Gwynne
mechanism to figure out if a port is usable or not later on.
2006-12-11define the command structs used by the ports.David Gwynne
this stuff isnt endearing me to ata at all, and apparently ahci is a good ata controller. the command path looks way more complicated than it needs to be (or maybe i am used to really good scsi controllers, i dont know). a lot of the terminology seems annoyingly different just for the sake of being different. i mean, what is the advantage of calling a scatter gather lement a "physical region descriptor table"? noone else calls it that. there's a lot of weird stuff in here. blah.
2006-12-11pull the wrapper for allocations of dma mem with a single segment in fromDavid Gwynne
arc, which got it from mpi, which got it from ami. grange is right, we should look at pushing it back up into the bus_dma api somewhere.
2006-12-11oops, too far for the match/attach funcsDavid Gwynne
2006-12-11give the function prototypes a bit more room for the return type.David Gwynne

2006-12-11allow bit 32 to be printed; bug spotted and fix tested by dlgTheo de Raadt
2006-12-11stash the field showing which ports are hooked up, and dump it if verboseDavid Gwynne
debug is on
2006-12-11if ahci debug and verbose output is enabled, then dump the cap register.David Gwynne
this also fixes a few reg definition errors i found after having them dumped. something seems really screwy with %b. i cant select the 32nd bit position using \x20 or \040, so im using \32 and the rest are octal (\oNN). hex (\xNN) seems really really borked, and the compiler doesnt like eating some of the dec ones (eg, \8BITNAME).

ignored previously.
2006-12-10restart collecting bits immediately after a parity error, i.e. use the frameMarc Balmer
immediately following the corrupt one; there is no no need to skip it by waiting for the next minute gap and the sensor value has valid data one minute earlier than before.
2006-12-10Fix typo in intersil clock programming.Miod Vallat
2006-12-10Re-arm signal loss detection only after we received a bit, not in itself. ThisMarc Balmer
prevents the signal loss function from being called repeatedly when we have no signal.
2006-12-10Faster synchronization after an unexpected minute gap.Marc Balmer
Only look at the skew value if it is != 0. Remove some dead code.
