mrg b8e9f36083 add COMPAT_12. 1996-08-26 23:39:36 +00:00
mark 4be6fcfb6e Only disable IRQs during cpu_switch(). FIQs can be left activeas they cannot
interfere with a context switch.
Fixed several comments.
1996-08-21 20:29:19 +00:00
mark 4522daecc9 Added defines for more proc structure fields (used by the FPE). 1996-08-21 20:26:41 +00:00
mark 7b0a0c0a24 Initial commit of the NetBSD/arm32 kernel TODO list. 1996-08-21 20:25:04 +00:00
mark 9d18e41fd8 No longer need the relocation function arm_fpe_mod_reloc() as this is now
sorted out at link time.
fpe_arm_header is now the header structure for the fpe and no longer
a pointer to a header structure.
1996-08-21 20:21:05 +00:00
mark 7b8910c01d Vastly simplified the FPE stubs code now that there are labels for all the
core entry points. i.e. the linker does the work rather than the stub code.
Optimised transferring the trapframe between UND32 and SVC32 mode stacks
in the fpe_post_proc handler.
Added experimental code to handle must of userret in UND32 mode. This means
that the copy of the trapframe and the switch to SVC32 mode is only needed
if mi_switch() has to be called. (This saves a vast number of pointless
trapframe copies).
1996-08-21 20:16:30 +00:00
mark 3142731d09 Re-written FPE core header.
Added branches relative to the start of the module and labels to the various
entry points.
All other offsets are now relative to _fpe_arm_start.
This removes the need for boot time relocation of the FPE.
1996-08-21 20:10:04 +00:00
mark e37583ac84 Removed the prototype arm_fpe_mod_reloc(). 1996-08-21 20:06:26 +00:00
mark 66d9ef4edb Updated with more info on the ARM7500 IOC/IOMD. 1996-08-21 20:00:50 +00:00
mark 9c8e5632da Replaced arch/arm32/arm32/fusu.c with arch/arm32/arm32/fusu.S
Added new iomd device.
1996-08-21 19:56:00 +00:00
mark 45bd77d893 Initial commit of a new iomd device. This device manages IOMD devices
for all ARM processors.
1996-08-21 19:53:21 +00:00
mark 64c91a1cc3 Report EASI space timings when probing the podule bus. 1996-08-21 19:46:47 +00:00
mark e8f3059a07 Define EASI space cycle types.
Added macro for setting the EASE space cycle time for a podule.
1996-08-21 19:44:53 +00:00
mark e53ec9745b Updated to work better with the new assembly functions like fuswintr().
Removed calls to traceback() as this info can be obtained via DDB after
a panic if needed.
1996-08-21 19:42:36 +00:00
mark 165dc50b4c This file can be removed now that the stubs functions it contained have
been replaced with proper assembly version in fusu.S
1996-08-21 19:38:39 +00:00
mark e75becbba3 Initial commit of proper [fs]uword() and associated functions. This
replaces fusu.c which comtained horrible stubs to things like copy{in,out}().
1996-08-21 19:37:43 +00:00
mark 663aa7fac0 Removed the #if notyet guards as this code now works.
Optimised the imsw16() and outsw16() functions by using ldm and stm
instructions.
1996-08-21 19:19:44 +00:00
mark caddfcc9e1 Make sure we have at least 1 rtc device configured otherwise
inittodr() and resettodr() will not work.
1996-08-21 19:07:19 +00:00
mark 88331f5ddc Removed debugging/diagnostic tracebacks. We have DDB now so can traceback
from there after the panic.
Guarded several checks with #ifdef DIAGNOSTIC
1996-08-21 19:04:17 +00:00
mycroft 1eba3fc001 Use to build `makemodes'. 1996-08-12 00:57:35 +00:00
mycroft 558d72128e Put into . Remove hooks for `config-dependent' and
`device-driver' flags.
1996-08-12 00:51:24 +00:00
mycroft cf67f29afe * Add a HOSTED_C_C variable, which strips `-p', `-pg', and
`-nostdinc', and use it when building genassym.
* Use `-nostdinc' just to be sure we're self-contained.
1996-08-10 06:07:57 +00:00
mycroft f94052ed3a * Define CWARNFLAGS and MKDEP in some moderately consistent fashion.
* Make S expand to an absolute path at compile time.
* Use `-S' rather than `-x' to remove debugging symbols.
* Garbage collect unused variables.
* Reverse a handful of port-specific changes that do not correspond to
the common build model and are not needed.

mrg 5abbf990f3 Change reboot(2) to take two arguments: bootopt like normal and also
a boot string for firmware that can do this, such as the SPARC and
the sun3 models.  It is currently silently ignored on all other
hardware now, however.  The MD function "boot()" has been changed to
also take a char *.
1996-08-09 10:30:23 +00:00
mark f5ee3d4ce6 Make sure all routes through vt_curadr() range check the x and y coordinates.
This fixes a nasty bug that could kill the kernel without ever reporting
a panic.
1996-07-05 19:07:55 +00:00
cgd af576d8a9f no need for a local implementation of SIOCGIFMTU; delete it.
s/ifr_metric/ifr_mtu/ where appropriate (in SIOCSIFMTU code), since
MTU data no longer (loggically) stored in ifr_metric.
1996-06-13 21:51:53 +00:00
mark 103a43ae29 Get the interrupt flags address from sc->sc_specific.sc_podule rather
than sc->sc_podule.
1996-06-13 18:29:45 +00:00
mark 31c4f7d574 Only read beyond the first byte of the podule header if we know that
an extended header is present i.e. don't assume an extended header as
however unlikely there could be a podule that doesn't have one.
Calculate an absolute address for the podule's interrupt mask rather
than leaving it relative to the base address of the podule.
If the interrupt status pointers are not present or are zero then
used the default bits as specified in the podule specification to
determine if the podule is interrupting.
1996-06-12 21:09:55 +00:00
mark 857439698b Claim the interrupt when leaving the interrupt handler as there can
only ever be a owner of the netslot interrupt.
Don't declare ebintr() as static.
1996-06-12 21:01:56 +00:00
mark 27ab616466 Don't claim the podule interrupts but pass them on in case of
chained podule interrupt handlers.
Fill out the ih_maskaddr and ih_maskbits fields in the interrupt handler
structure so that interrupt dispatcher knows where to look to determine
if the handler should be called.
General code tidy up and source code formatting.
1996-06-12 20:59:10 +00:00
mark 4dd0dabfca Don't claim the podule interrupts but pass them on in case of
chained podule interrupt handlers.
Fill out the ih_maskaddr and ih_maskbits fields in the interrupt handler
structure so that interrupt dispatcher knows where to look to determine
if the handler should be called.
1996-06-12 20:46:58 +00:00
mark e5aad86168 Allow the mouse interrupt to be specified in the config file. Fall
back on timer 1 interrupts if none is specified.
Only set up timer 1 is the driver is using timer 1 interrupts.
Don't claim the interrupt but allow them to be passed on to other
handlers.
1996-06-12 20:30:59 +00:00
mark 7d688793a8 Claim the interrupt if it has been dealt with otherwise pass it on. 1996-06-12 20:28:29 +00:00

masks.
1996-06-12 20:19:35 +00:00
mark 1fd9b6f37c Removed some dead code that could never get executed (followed a panic).
Updated several panic messages to indicate what part of the fault code
they came from.

mark 977f90bd3b Removed copyin()/copyout() stub code.
Removed several old debugging functions that are no longer needed.
Block interrupts while updating the soft interrupt masks.
Fixed softclock interrupts and added IRQ_SOFTPLIP to the SPL_SOFT mask.
1996-06-12 20:12:04 +00:00
mark 47c523fff0 Spilt the copyinout() function into two separate functions copyin()
and copyout() so that the address space checks are done here rather than
in a bit of stub code.
1996-06-12 20:06:00 +00:00
mark 7b05ce2841 Updated to match changes in the irq handler structure.
Define symbols for the address space limits that copyin() and copyout()
compare against.
1996-06-12 20:02:42 +00:00
mark 13ff05d513 Don't claim the interrupts in hardclock() and statclock() but allow
them to be passed on to other interrupt handlers attached to the
timer interrupts.
1996-06-12 20:00:21 +00:00
mark b8dfbd8fe6 Don't use signed compares when determining the copy direction. 1996-06-12 19:58:43 +00:00

moment.

mark 544631c0be Guard structures and prototypes with #ifndef _LOCORE
Rename the currently unused irq handler structure fields for podule
interrupts so they make more sense.
Define IPL_NONE as a positive value instead of -1 and increase the
number of IPL levels.
1996-06-12 19:47:11 +00:00
mark 4d280731dd Updated comments.
Print the irq masks for IPL_NONE.
