thorpej babefc5331 Add BUS_DMA_READ and BUS_DMA_WRITE flags, that hint the back-end 
at dmamap load time that the mapping will be used for a unidirectional
transfer of the specified direction.

darcy ce0ec1e208 Add System V semaphore resource limits to each GENERIC file that has an 
option for System V semaphores.  It appears that there are no overrides
in the code and each file has the following added.

 options    SYSVSEM     # System V semaphores
+#options   SEMMNI=10   # number of semaphore identifiers
+#options   SEMMNS=60   # number of semaphores in system
+#options   SEMUME=10   # max number of undo entries per process
+#options   SEMMNU=30   # number of undo structures in system
 options    SYSVSHM     # System V shared memory

If anyone thinks that this is incorrect for any of these files, please
correct it.

Note - the i386 port was not forgotten.  It was done separately.

marcus bc069b939c Abstracted handling of System ASIC controlled IRQ:s a little. 
Three different IRQ:s can be selected for each event, 9, 11, or 13
(which selects hardware priority).  More events to be added as they
are discovered.  Do not use shb_intr_establish() to register IRQ 9, 11
or 13 anymore.

thorpej 1c3a62e066 Sprinkle pmap_update() calls after calls to: 
- pmap_enter()
- pmap_remove()
- pmap_protect()
- pmap_kenter_pa()
- pmap_kremove()
as described in pmap(9).

These calls are relatively conservative.  It may be possible to
optimize these a little more.

lukem 20ba07f2fe - add dev_noimpl(xxx,yyy) macro to replace "(dev_type_xxx((*))) yyy", 
and use appropriately

- create more helper macros:
   . cdev__xyz_init(c,n), such as cdev__ocri_init() for
     /* open, close, read, ioctl */, etc.
   . cdev__xRy_init(c,n), where nullop is used instead of enodev to dummy out
     method `R' and the comments now read /* xxx (read) yyy */ instead
   . cdev__xyz_t_init(c,n,t) - as per cdev__xyz_init, but sets d_type = t
     as well

- use seltrue instead of dev_noimpl(poll,*), as (IIRC) cdevsw.d_poll should
  always DTRT WRT returning a valid result.  (a few devices previously
  incorrectly returned ENODEV)

- use dev_noimpl(stop,enodev) instead of dev_noimpl(stop,nullop) if tty
  == 0, because it doesn't matter if dev_type_stop isn't implemented in that
  case, and it allows the use of the cdev__xyz_init macros. certain ports
  (sparc,sparc64,x68k) used the nullop method for dev_type_stop in a few
  drivers, whereas everything else uses enodev

- ensure that the comments are accurate WRT the behaviour of a given entry

thorpej 40c4d1e0c3 Rename the CLI/STI/ECLI/ESTI macros to more descriptive names, 
and add comments to describe exactly what they do (because it's
not totally obvious at a glance, due to the number juggling necessary
to frob the correct bits in SR):

CLI -> EXCEPT_DISABLE (sets SR.BL)
STI -> EXCEPT_ENABLE (clears SR.BL)

ECLI -> INTR_DISABLE (sets SR.I[0-3])
ESTI -> INTR_ENABLE (clears SR.I[0-3])

thorpej f16d219c1b Config glue for rasops/wsfont. 2001-02-01 01:27:04 +00:00
thorpej fbfc0872d8 New PowerVR display driver, based on the TURBOchannel "cfb" 
driver by Tohru Nisimura (a very good framework for a FB driver,
BTW!), using bits of Marcus's original driver for the hardware
access.

The main advantage of this version is that is uses rasops (which
is faster than the rcons stuff) and wsfont, so you can select the
console font in the kernel config file.  Using the BOLD8x16 font,
you get an 80x30 console (vast improvement compared to the Gallant12x22
font).
