4742fe7a4d When memory mapping a PCI device (like XFree86 does) on an XP1000, we must
use ALPHA_PHYS_TO_K0SEG(offset) rather than just plain offet.  I've verified
that this does not break other platforms (I've tested an AlphaStation 200
and a Personal Workstation 500au with this patch).

As to why this works, well.. Its black magic as far as I know.  I obtained
this hack from Myricom, who in turn, obtained it from Compaq engineers.
Without this hack, XFree86 cannot talk to a PCI graphics card.

f9476829d0 A forgotten bit of my ST6600 commit 1999-05-27 22:03:31 +00:00
Andrew Gallatin
7ae6cdbca2 Add support for the DEC_ST6600 family of alphas. This includes the
Compaq XP1000, AlphaServer DS20, AlphaServer DS10, and DP264

This has been tested *only* on XP1000's.  I'll be interested to hear from
owners of other types of DEC_ST6600 alphas.

I'd like to thank Don Rice of Compaq for providing the documentation required
to support this platform on FreeBSD.  I'd also like to thank Doug Rabson for newbus,
and for helping me get a multiple hoses working with newbus.

50b8d1cce4 Allow chipset drivers to specify the direct-mapped DMA window's mask in
preparation for tsunami support.  Previous chipsets' direct-mapped DMA
mask was always 1024*1024*1024.  The Tsunami chipset needs it to be
2*1024*1024*1024

These changes should not affect the i386 port

|Check for page being resident when doing I/O with /dev/kmem and return
|EFAULT if it is not resident. This prevents the system from manufacturing

a3be63b3ce * Factor out the common code between the isa bus drivers for i386 and alpha.
* Re-work the resource allocation code to use helper functions in subr_bus.c.
* Add simple isa interface for manipulating the resource ranges which can be
  allocated and remove the code from isa_write_ivar() which was previously
  used for this purpose.

6d04a6cb97 I'm sick of the automatic rename of /kernel to /kernel.old while doing
development that leads to lots of crashes during boot.

I have made a 'reinstall' target (like in ports, and reinstall.debug)
This is most useful if you want to keep /kernel.old as a known bootable
kernel.  If you test a new kernel and have to reboot for a fix, a
'make reinstall' will install the new kernel over the top of the old
non-viable one, leaving the old one untouched.  This is mainly meant
for development, not general users.

4be2eb8c49 I got tired of seeing all the cdevsw[major(foo)] all over the place.
Made a new (inline) function devsw(dev_t dev) and substituted it.

Changed to the BDEV variant to this format as well: bdevsw(dev_t dev)

DEVFS will eventually benefit from this change too.

46eede0058 Continue where Julian left off in July 1998:
Virtualize bdevsw[] from cdevsw.  bdevsw() is now an (inline)
        function.

        Join CDEV_MODULE and BDEV_MODULE to DEV_MODULE (please pay attention
        to the order of the cmaj/bmaj arguments!)

        Join CDEV_DRIVER_MODULE and BDEV_DRIVER_MODULE to DEV_DRIVER_MODULE
        (ditto!)

(Next step will be to convert all bdev dev_t's to cdev dev_t's
before they get to do any damage^H^H^H^H^H^Hwork in the kernel.)

84b399de51 Changes to support diskless booting on the alpha:
* Make the network code in the bootstrap more chatty (helps debugging)
* Add nfs root stuff to cpu_rootconf(). I also added a check to make sure
  it really was netbooting which allows the use of the same kernel for local
  and network boots.
* Tweak the de driver so that it takes the speed setting from the console
  for the alpha (some PWSs have broken de chipsets). This is the same
  behaviour as NetBSD/alpha.
