print the "can't get bus clock" message. While there, adjust comments for the i3/i5/i7 CPUs and include the relevant Xeon models. The Intel marketing people seem to have less influence on the Xeon names, so they describe the CPU generation much better. ok marco@, deraadt@
2010-12-29the random ioctl stuff is not very useful. I want to see all theTheo de Raadt

2010-12-29implement timeouts of scsi commands.David Gwynne
timed out scsi commands get put on a list and an iohandler is scheduled. that iohandler pulls the timed out scsi command off the list and issues a task management request to kill all outstanding io on the target with the timed out io. all io killed as a result of this request will be returned to the midlayer with their status set to XS_RESET, which in turn will cause the midlayer to retry the command. this relies on the previous commit.
2010-12-29make mpii properly detach devices, which helps a lot if they have commands ↵David Gwynne
in flight. to relevant changes are: - call the activate(DVACT_DEACTIVATE) function against all the luns on the target that is going away as soon as possible. - issue the target reset BEFORE detaching the children devices. this is needed now tha the midlayer will sleep until all outstanding commands on a device come back from the adapter before calling the child devices attach routine. tested on straight disks and on disks in enclosures. ok and moral support from krw@

x86_atomic_*_l(), and update the callers of all of those to use the underlying x86_atomic_*_u32() functions that they were expecting anyway. Whether the x86_atomic_*_ul() macros should be eliminated has been deferred. ok kettenis@, tedu@

2010-12-27Do not issue a cache maintainance operation until the last one is notMiod Vallat
completed; this used to be the case, but revision 1.25 of this file, close to four years ago, changed this behaviour by mistake. The side effects of this mishandling of the cache did not show up until the kernel memory allocation strategy moved towards fast reuse of freed pages. Took me a while to track this down, maybe I'm getting too old to write code, I probably should write backdoors instead.

a physical address [more precisely, something suitable to pass to pmap_enter()'sphysical address argument]. This allows MI drivers to implement mmap() routines without having to know about the pmap_phys_address() implementation and #ifdef obfuscation.

2010-12-23Better malloc the right size, overruns are so 200x... Pass the brown paperMiod Vallat
bag, please.
2010-12-23The exception vector page on m88k systems has always been the same page asMiod Vallat
the one used by the firmware, which (at least on mvme88k) is at address zero. This is unfortunate, since this means that NULL pointer dereferences in the kernel are not caught, and writes cause havoc. This behaviour was necessary to be able to use the PROM system call interface during early bootstrap, without having to disassemble the VBR page and update branches - which use pc-relative displacement - if we were to use a different VBR address. On mvme88k, change this and actually set up two VBR pages: one, over the PROM page (except for the system call vectors), and another one in the kernel image (which will be mapped read-only). We'll run with the PROM page until the end of autoconf, and then switch to the kernel one, and unmap all the PROM below it. As a bonus, the final kernel page can use optimized data access fault handlers, which do not have to check for faults caused by badaddr(), since badaddr() is only used during device probe on buses which do not support hotplug. There are a few infrastructure collateral damage on aviion and luna88k, but these ports do not change their behaviour yet.

2010-12-23Make the pte created by pmap_map() wired, and count them in pmap_kernel()'sMiod Vallat
statistics. This allows these mappings to be removed with pmap_kremove() without messing with accounting.
