1997-05-08 13:44:11 +00:00
matthias 9dd24ca41c * Print device information in md_attach_hook. Since this is a pseudo device,
we have to output the device name as well.

  used for debugging. Thank's to Ian Dall for this suggestion.
1997-04-01 16:37:43 +00:00
matthias af88eb9d75 * Fixes from Ian Dall. Make the ieee handler compile with the new gcc warning

matthias bf4354241e * Use machine/conf.h instead of sys/conf.h to get the
lpt{open,close,write,ioctl} prototypes.
* Remove the cdev_decl(lpt). We get it from machine/conf.h.

* Use machine/conf.h not sys/conf.h to get the prototypes for the
  scn cdev functions.
* Include <sys/kgdb.h> to get prototypes for kgdb_connect and kgdb_attach.
* Add missing prototypes for some functions.
* Make ddb work before the console was opend. Thank's to Ian Dall
  for this change. His comment:
	Also, ddb doesn't work if a break is set before the console
	is opened. That is because DTR and RTS are not asserted. It
	would probably work if the console is wired to ingnore DTR
	or RTS. The change below is probably not very correct.
	Proabably the state of DTR and RTS should be saved and DTR
	and RTS asserted on the start of a polled serial input and
	the saved values restored on exiting polled input
* Remove unused function scn_ei.
1997-03-20 12:03:03 +00:00
matthias 80502accfe * Remove unused ncr_minphys prototype.
* Add prototype for ncr_ready.
* Add ncr_wait_not_req function from Ian Dall:
	The ncr_wait_not_req business is to avoid a potential race.
	When the pseudo DMA finishes, the target may not have
	lowered REQ yet. If we just charge ahead, we eventually test
	for phase when REQ is high. However, if REQ has not yet gone
	low for the last byte transferred, this will be the wrong
	phase. This is taken from the dp8490 application notes. The
	last ACK is not deasserted until the dma is completed.
	Deasserting the last ACK should be delayed until the last
	REQ is deasserted. I am not sure if there are ever devices
	this slow, but I believe the code is "more correct".

thorpej 69d841a462 Add the "se" device at cdev major 22. 1997-03-18 01:41:40 +00:00
is 07b064e02e New ARP system, supports IPv4 over any hardware link.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.

matthias d8319f5c75 remove leftover from switch to the mi kgdb interface. 1997-03-13 10:25:25 +00:00
matthias c6d2740564 Integrate Phil Budne's latest changes to the scn driver. From his README:
* Uses Counter/Timer dynamicly for rate generation; You can
	  have both 19200 and 38400 on one duart, and 57600 on another!
	* Improved scninfo program to dump driver internal information.
	  implemented counters for parity err, framing err, break
	* Delays changes until transmitter idle to avoid "glitches"
	* Cleaned up scn_softc member names
	* Untested support for sc26c92 (I don't yet have any to test with);
	  + Will use alternate rate tables (include 115.2kbps and 230.4kbps)
	  + Will raise FIFO rx interrupt threshold and watchdog timer
	    at higher rates.
	  + Unknown (to me) how fast pc532 MC145406 driver chips can go

	NOTE: It seems like it may be a BAD idea to use a sc26c92 as
	a console port for now; the PROM doesn't know to reset the
	chip back to scn2692 mode!!

1997-03-01 09:49:45 +00:00
matthias 63183795c0 imask[IPL_ZERO] was updated after recomputing the run masks for all the
interrupt handlers. Due to this
  - DIAGNOSTIC kernels would panic
  - check_sir would run with the interrupt registered last blocked
Credits for finding and fixing this go to Ian Dall.
1997-03-01 09:49:44 +00:00
matthias 597322b455 * Adapt to changed definition of struct db_variable.

gwr 2de163471e Minimal changes to adapt to removal of NCR5380_PERMIT_RESELECT.
This driver should be updated to allow per-target control over
disconnect/reselect, but I will leave that to the port masters.

matthias f3cdc89574 * Use Phil Budne's full name in the copyright header.
* Define RECOVER to something faster.
* Check for a valid softc in scnsoft. When there is
  a "hole" (e.g. you have scn0,scn1, scn4, scn5) the
  old code would panic. Thank's to Phil Budne for
  finding and fixing this bug.

matthias 6f5bca455b * Remove whitespaces from empty lines.
* Add (commented out) type and asmtype commands. asmtype will
  be used to define the gcc constraint used to emit constants
  and type will be used to define the type the constant should
  get casted to before passing it to printf.
1997-02-08 09:33:52 +00:00

matthias 1370131ffd Add scripts and documentation for a new method to create assym.h files.
With the kern/genassym.sh script HOSTED_CC is no longer used to create
assym.h files. This should make crosscompilation easier.

thorpej 7b40f5228e "md" is declared in sys/conf/files, now. 1997-01-21 09:39:20 +00:00
perry b89a3425b7 Eliminate obsolete TIMEZONE and DST options.
Eliminate obsolete global kernel variable "struct timezone tz"
Add RTC_OFFSET option
Add global kernel variable rtc_offset, which is initialized by
RTC_OFFSET at kernel compile time.
on i386, x68k, mac68k, pc532 and arm32, RTC_OFFSET indicates how many
minutes west (east) of GMT the hardware RTC runs. Defaults to 0.
Places where tz variable was used to indicate this in the past have
been replaced with rtc_offset.
Add sysctl interface to rtc_offset.
Kill obsolete DST_* macros in sys/time.h
gettimeofday now always returns zeroed timezone if zone is requested.
settimeofday now ignores and logs attempts to set non-existant kernel
timezone.

* Add IPL_HIGH. Alias IPL_HIGH to IPL_RTTY
* Define splrtty (used by the scn driver).
* Add iv_level and iv_mask to struct iv. These define the IPL at
  which the handler should run.
* intr_establish now takes *two* ipls. One at which the handler should run,
  and one in which the interrupt should get blocked.
1996-12-23 08:37:41 +00:00
matthias b01c5dfbcb * Define NKPDE_BASE, NKPDE_MAX and NKPDE_SCALE for boottime computation of
nkpde (From the i386 port).
1996-12-23 08:37:38 +00:00
matthias b30b4f9fcf * Define new sysctl variable "machdep.nkpde" (From the i386 port). 1996-12-23 08:37:37 +00:00
matthias 41cc99aa8c * Rearange duart_info and add hwflags to store uart type (Ian Dall).
* Define SCN_RING_HIWAT and add sc_rbhiwat to scn_softc. When the
  ringbuffer gets full up to this mark, rts gets asserted (Ian Dall).
* Add sc_rx_blocked to scn_softc. This is used to tell scnsoft that
  rxinterrupts are blocked (Ian Dall).
1996-12-23 08:37:11 +00:00
matthias 2c7e970491 * Define the bits in MR0 for the SCC26C92 (Ian Dall).
* Define SCC26C92-only commands (Ian Dall).
1996-12-23 08:37:10 +00:00
matthias b080d4fea0 * Match functions take a "struct cfdata *" as their second argument.
* intr_establish now takes *two* ipls. One at which the handler should run,
  and one in which the interrupt should get blocked.

All the following changes were provided by Ian Dall:
* Remove SCN_HSOFT. Now that the pc532's software interrupt system is running
  from int14, this won't work anymore.
* Add code to detect uart type (SCN2681, SCC2692 or SCC26C92).
* Cleanup my RECOVER mess. Thank's to Ian Dall for reading the datasheet
  and removing all the unnecessary RECOVERs.
* Cleanup scnrxintr.
* Implement scnhiwflow.
* Do not use automatic RTS. This and scnhiflow and some changes to the
  interrupt system suggested by Ian fix the scn overrun problem at 57600
  baud.
1996-12-23 08:37:07 +00:00
matthias 70597563c6 * Match functions take a "struct cfdata *" as their second argument.
* intr_establish now takes *two* ipls. One at which the handler should run,
  and one in which the interrupt should get blocked.
* Make transfersize configurable for input and output. Default the input
  transfersize to 128 bytes. That way interrupts won't be disabled for more
  then about 128us-256us for slow targets. This is necessary to prevent scn
  fifo overruns. Cleanup the pdma code. Thank's to Ian Dall for these
  changes.
