is dc914f2ee7 Only create verbose delay loop calibration message for DIAGNOSTIC kernels. 1997-09-15 22:17:55 +00:00
is 4d8c2c3528 Make Amiga battery clocks autoconfiguration devices, so that they can be
left out of specialized configurations.

is fc3de9d828 Make the DraCo hardware clock an autoconfiguration device. 1997-07-17 23:29:28 +00:00
is 487476c2a9 Implement the RTC_OFFSET kernel option/rtc_offset variable for the Amiga port.
To get the old behaviour, set options RTC_OFFSET=0 in your kernel configuration
file.

is 5e6f97d4ef A first hack at DraCo real-time clock support; only reads clock, currently.
Also only whole seconds are used (while the hardware provides 1/256 seconds).

veego 9aca91d78c Converted for the use of sys/dev/clock_subr.[ch].
Add some comments about the a2000 oki clock chip and stop the clock while
writing.

is 9ad0171cce Use the right parameter to decide whether it's early configuration. (I wonder
why this worked with some configurations... it shouldn't have).

While we're here, correct the 2.4% error in the delay divisor message.

veego 94b6312429 Get rid of __BROKEN_INDIRECT_CONFIG. 1996-12-23 09:09:49 +00:00
is b71e65949f Make clock an early configuration device, configured before early console
configuration. This way, the delay loop is calibrated before graphics and
serial hardware is touched.

This change should smooth pr 2890 by Thorsten Frueauf (also privately
reported by Laurent Badoukh). While the real problem with those is the
paranoically high delay() calls in the grf_cl initialization, it was made
even more visible by the miscalibrated (to the save side) new style delay
loop.

is 5a86eaccfc a) replace our delay() with a Gordon Ross style one, calibrated at
clock_attach() time (for now).
   This removes our dependance on the DraCo ROM access timing and frees
   the second CIA on Amigas.
b) support for DraCo rev. >= 4 native timer chips.
1996-09-29 21:27:30 +00:00
is 0569d3582c Use the right microsecond delay address. To achieve this, also map that
piece of hardware into kernel virtual memory (was only a guess 'til now).
XXX Unfortunately, the hardware vendor reserves the right to change this in
future DraCo revisions. We must rethink delay() and DELAY(), at least for the
DraCo, soon.
1996-06-20 09:31:58 +00:00
is 59bbde87bc Don't use the inline assembler 64bit integer division if our kernel might
run on 68060. Some graphics boards need delay() in early initialization (that
is, before initcpu() was called.
1996-06-18 11:41:48 +00:00
is e138ae4f38 Clean up the mess I left over from my yestereve's commit: partially unused
variables left over from color background debugging, partially wrong #ifdefs
making some variables unused in non-M68060 kernels.
1996-05-10 14:30:53 +00:00
is f6ab1073c8 First part of M68060 and DraCo support.
* for the M68060 part: store buffer and branch target cache aren't
  enabled yet (this needs cleanup of lots of locore.s code which is a
  maze of little passages, all a little different) (and it wasn't yet
  tested in an accellerated Amiga, only in the DraCo).

  I've included a workaround for 2 of the CPU bugs in chips with Masks
  1F43G and earlier, but didn't bother to deal with the can of worms
  in the [0-3]D11W chips. Be sure to get "68060 rev. 1" or more
  reported at kernel startup time, or at least mention it (or the mask
  revision, if available) when reporting problems.

* for the DraCo: only machines with a CIA timer.

  I assigned machine id 32000+nn (0x7Dnn), where n is the machine
  readable Quicklogic custom chip revision (also printed at boot
  time).  "Guaranteed to work" up to rev. 3, newer DraCo's aren't
  guaranteed to have any CIA (we don't have a driver for the new timer
  yet).

  Supported are:

  - MF-II keyboards on the native interface and A3000 keyboards via
    the CIA.
  - builtin SCSI interface (yet another instance of siop)
  - CIA timer.
  - Zorro II devices which don't do DMA (don't get mapped to Zorro II
    address space in the DraCo)
  - "local bus" devices which are autoconfigured by the boot rom
    (should be all); only an Altais driver is there (looks like a Retina Z3)

  Not yet supported are:

  - native timer of newer machines.
  - Real Time Clock.
  - serial, parallel + floppy on the SuperIO chip (that is also: no mouse)

  XXX You need an enhanced boot loader, which will committed in a few days.

  XXX std.draco should and will go away.

veego 974e9f6e22 - Cleanup for -Wall and -Wstrict-prototypes
- Added support for multiple floppy drives
- CyberVision64:
        - has now a real console mode
        - another bugfix for boards with the new S3 chip
- Ariadne:
        - fixed crashes with aeput (mbuf failure)

mhitch b00a2c1e30 Clean up typos and other errors from new device attachment changes. 1996-03-17 05:53:57 +00:00
thorpej 5c67e5fad9 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

interrupts to level 4 (deal with icky built-in serial port)

chopps 15d4cf6bf9 resistance is futile, you will be assimilated.
amiga goes: config.new *and* /sys/scsi.
clock code coerced into a single .c file adding an accurate usec delay().
disklabel.c updated to DTRT, code to write RDB's to be added soon.
sbic (old scsi) converted over to new scsi and config this covers about
90% of users.  Other drivers soon.
