2010-11-18Do not #include <sys/dkstat.h> if you don't need anything from it.Miod Vallat
ok krw@ deraadt@
2010-09-20Get rid of evcount's support for arranging counters in a treeMatthew Dempsky
hierarchy. Everything attached to a single root node anyway, so at best we had a bush. "i think it is good" deraadt@
2010-07-02Move common code for waking up writers on a tty into a function.Nicholas Marriott
ok deraadt matthew millert
2010-06-28Remove all adapter-specific 'struct scsi_device's. They are never used. FirstKenneth R Westerback
step in elminating 'struct scsi_device' entirely. Spotted and initial diff from matthew@. ok matthew@ dlg@ deraadt@ marco@ miod@
2010-06-28Allow tty drivers to request larger buffers at attach time using aTheo de Raadt
max-baud-rate hint. Adjust TTYHOG (the nearly full logic) to this new situation. The larger buffers are required by the very high speed KDDI devices in Japan (CF com, or USB ucom) so those are the only two drivers which currently ask for a larger buffer size. ok yasuoka miod
2010-06-27Bunch of include adjustements to restore compilability.Miod Vallat
2010-06-26Don't #include <sys/user.h> into files that don't need the stuffPhilip Guenthe
it defines. In some cases, this means pulling in uvm.h or pcb.h instead, but most of the inclusions were just noise. Tested on alpha, amd64, armish, hppa, i386, macpcc, sgi, sparc64, and vax, mostly by krw and naddy. ok krw@
2010-05-20New scsi code seems to be stable. Pluck previously identifiedKenneth R Westerback
low-hanging splbio/splx pairs that are no longer needed and see if this reveals any hidden scsi flaws. ok dlg@
2010-04-12Some of the line disciplines want to check for suser. Better to pass themTed Unangst
a process instead of using curproc. ok deraadt
2010-03-23Change the scsi_cmd function member of scsi_adapter from int toKenneth R Westerback
void. Use XS_NO_CCB error in the scsi command (xs) to report the NO_CCB condition. Eliminates all SUCCESSFULLY_QUEUED and COMPLETE confusion and untangles the midlayer from the adapter a bit more. Eyes and some fixes by miod@ There may be some compile issues on little used (i.e. I don't have any) drivers but the change is mechanical and thus easy to remedy. ok dlg@
2010-01-10Set ITSDONE in scsi_done() and zap trivial instances of setting itKenneth R Westerback
in the drivers just before calling scsi_done(). ok dlg@ beck@
2010-01-09Zap all setting of ITSDONE in drivers that don't look at it. NobodyKenneth R Westerback
else cares so it's just noise. Drivers that actually look at ITSDONE are unchanged. ok marco@ (for his files) dlg@ beck@
2009-11-22Bring last drivers fully into the NO_CCB world by replacingKenneth R Westerback
TRY_AGAIN_LATER uses with equivalent NO_CCB. Eliminates confusion between the two as was always intended. buf I/O's that can't be started get pushed back onto the front of the queue and retried. Others get sent back to originator as failures. No more epi-cycle looping inside the SCSI midlayer hoping the problem goes away. Various testers, no objection from miod@ as vs(4) was tested by nick@.
2009-11-09Every selwakeup() should have a matching KNOTE() (even if kqueue isn'tNicholas Marriott
supported it doesn't do any harm), so put the KNOTE() in selwakeup() itself and remove it from any occurences where both are used, except one for kqueue itself and one in sys_pipe.c (where the selwakeup is under a PIPE_SEL flag). Based on a diff from tedu. ok deraadt
2009-10-31in the absense of link state handling, drivers should still be silent; ok miodTheo de Raadt
2009-10-31Use suser when possible. Suggested by miod@.Federico G. Schwindt
miod@ deraadt@ ok.
2009-10-31Add missing KNOTE() calls after selwakeup(), until we decide if the KNOTE()Theo de Raadt
calls can go directly into selwakeup() safely long discussion with nicm, murmers of consent from tedu and miod, noone else seems to care of kqueue is busted as long as it makes their sockets move data fast... pretty sad.
2009-05-31Fix definition of CL_FIFO_MAX to match what the hardware can do; this inMiod Vallat
turn fixes a stack smash in cl_rxintr().
2009-03-29make various strings ("can't map mem space" and similar) more consistentStuart Henderson
between instances, saving space in the kernel. feedback from many (some incorporated, some left for future work). ok deraadt, kettenis, "why not" miod.
2009-03-09Switch mvme88k to timecounters.Miod Vallat
2009-03-05Change SMP secondary processor startup to have them ``hatch'' earlier,Miod Vallat
so that they can invoke sched_init_cpu() before the scheduler starts, which allows the horrible kluge in cpu_configure() to die.
2009-03-04When handling clock interrupts, check the overflow counter to know how manyMiod Vallat
times hardclock() needs to be invoked; fixes clock drift found on 197DP with SMP kernels.
2009-02-18Fix thinko in list traversal in vsbic_cmd_ccb().Miod Vallat
2009-02-17Be sure to pass a valid confargs * to child devices of vme0 when attaching,Miod Vallat
for they will attempt to dereference it and having NULL readable while in the kernel is just cheating.
2009-02-16Extend the scsi_adapter minphys() callback to take a struct scsi_link *Miod Vallat
as additional argument. This will allow intermediate layers between scsi devices such as sd and scsi host adapters to take appropriate action if necessary.
2009-02-15Properly send a request sense command if the command status asks for it.Miod Vallat
2009-02-14Add vsbic(4), a drive for the MVME327A SCSI and floppy controller, only forMiod Vallat
the SCSI part so far.
2009-02-14Fix a few defines.Miod Vallat
2009-02-13Provide a specific delay() routine using separate timers for the two cpusMiod Vallat
on MVME197DP boards running the MP kernel.
2009-02-12BPP routines for ``intelligent'' Motorola MVME boards. Currently not usedMiod Vallat
by anything, will eventually be used by the vx(4) MVME332 driver (once I take the time to fix it) and the vsbic(4) MVME327 driver being worked on.
2009-02-08Use the correct flags when bus_dmamap_sync()ing the s/g lists.Miod Vallat
2009-02-01Nuke whitespace at EOL.Miod Vallat
2009-02-01Finally switch this driver to bus_dma.Miod Vallat
2009-01-29Add a few cache operations after I/O completes.Miod Vallat
2008-11-28Eliminate the redundant bits of code for MTU and multicast handlingBrad Smith
from the individual drivers now that ether_ioctl() handles this. Shrinks the i386 kernels by.. RAMDISK - 2176 bytes RAMDISKB - 1504 bytes RAMDISKC - 736 bytes Tested by naddy@/okan@/sthen@/brad@/todd@/jmc@ and lots of users. Build tested on almost all archs by todd@/brad@ ok naddy@
2008-10-02First step towards cleaning up the Ethernet driver ioctl handling.Brad Smith
Move calling ether_ioctl() from the top of the ioctl function, which at the moment does absolutely nothing, to the default switch case. Thus allowing drivers to define their own ioctl handlers and then falling back on ether_ioctl(). The only functional change this results in at the moment is having all Ethernet drivers returning the proper errno of ENOTTY instead of EINVAL/ENXIO when encountering unknown ioctl's. Shrinks the i386 kernels by.. RAMDISK - 1024 bytes RAMDISKB - 1120 bytes RAMDISKC - 832 bytes Tested by martin@/jsing@/todd@/brad@ Build tested on almost all archs by todd@/brad@ ok jsing@
2008-09-23Fix uninitialized variable.Miod Vallat
2008-07-30Do not print adapter target id on the attachment line, now that scsibus(4)Miod Vallat
prints it. These should be the last offenders.
2008-01-23Cleanup cn_pri. Change constants to more meaningful names, rather thanJoel Sing
the hp300 related ones currently in use. CN_NORMAL becomes CN_LOWPRI, CN_INTERNAL becomes CN_MIDPRI and CN_REMOTE becomes CN_HIGHPRI. ok miod@
2008-01-05For each channel, tell if it is single-ended or differential if we can knowMiod Vallat
this. Might help before someone sets his disks on fire. Especially with boards where not all channels are of the same type.
2008-01-03Enable wide transfers in the IOPB on wide busses, and get the IOPB passthroughMiod Vallat
SCSI commands length correct (it's a length in 16 bit words, not in 8 bit bytes).
2008-01-01Match on Cougar boards, and try to drive them like Jaguars on steroids. OnMiod Vallat
wide Cougars, use one command queue per target and disable lun support, so that we do not overflow the board's memory; and since we are behaving as a Jaguar, do not do tagged queuing or synchronous transfer negotiation. Tested on two MVME328XT-2 (4220 and second revision artwork 4220) narrow Cougar-I (but wide external connectors), but probes fail with select timeout so far; I could not get various Motorola BUG to probe devices on these boards either, so we're even (and maybe both my boards are toast, but I won't bet money on this).
2008-01-01A potpourri of bugfixes:Miod Vallat
- switch back to a fixed queue number allocation, but keep the rotating command queue entries. Force openings to 1 because of this. - make sure to mark the queue as ready before invoking scsi_done(), which could trigger a request for the same target. - allocate a command queue and an IOPB at the same time, instead of using two routines and ugly queue pointer arithmetic. This makes the daughterboard work, as long as the first scsi chain is not empty.
2007-12-27Make the mvme188 interrupt handling closer to the aviion interrupt handling:Miod Vallat
non-VME syscon interrupt sources will now use their own intrhand array, and interrupt sources will be enabled in the arbiter as interrupt handlers are registered. This allows VME devices to use the whole 256 interrupts range.
2007-12-25Increase timeout on the processor bus when running without snooping enabled.Miod Vallat
This lets 40MHz MVME197LE boards run with instruction cache enabled, and also fixes random instruction faults occuring on the early 50MHz models.
2007-12-20Stricter range checks in mmap function.Miod Vallat
2007-12-15All MVME BUG manuals concur on SR3 being the only register needing to beMiod Vallat
preserved across BUG calls, but on the other hand the last 16 traps need to be restored to BUG values, not only trap #496.
2007-12-13Disable write posting, this does not work on BusSwitch revision #1. The BUGMiod Vallat
should do this for us, but better play safe.
2007-12-04Work in progress SMP code for 88110 processor using the BusSwitch chip asMiod Vallat
an IPI facility, for MVME197DP. It's still missing a few remote cache IPIs and IPI do not seem to be reliably triggered on remote processors at the moment (but this could be a problem on the board I am currently testing on), at least it will boot multiuser using only cpu0 to schedule processes.
