64860a1d74 Print the instruction word for undefined instructions. 1996-08-29 22:25:26 +00:00
mark
7568e05e32 Added machine command for reporting panic related information.
Trap undefined instructions that are used for breakpoints for all
processors modes. If the mode was USR32 then post a SIGTRAP signal.

2fb1f405f7 Added a new machine function to report information following a panic
e.g. panic string, message buffer etc. This is to aid debugging panics
following a panic while X was running as X will swallow all the panic
text.

75a39e190b Replaced the generic copystr() and copystrinout() functions with
optimised copystr(), copyinstr() and copyout() functions.
This removes the need for the copy{in,out}() stub code in stub.c

8b3ff9c94f Added support for NFS root and swap.
Define argdev here.
Fixed the interpreting of the root and swap devices passed from the
boot loader.

2c16eec75d Removed declarations of swapdev and argdev. These are now defined
elsewhere.

71ad30d0e9 (1) set scsi_link channel to either the appropriate channel (if a
multi-channel driver), or to SCSI_CHANNEL_ONLY_ONE if a
    single-channel driver.
(2) use scsiprint() rather than a locally-defined autoconfig print
    function, and kill any locally-defined print function.

2a73ef60b7 change cfprint_t type definition to take a const char *, rather than
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).

4be6fcfb6e Only disable IRQs during cpu_switch(). FIQs can be left activeas they cannot
interfere with a context switch.
Fixed several comments.

7b0a0c0a24 Initial commit of the NetBSD/arm32 kernel TODO list. 1996-08-21 20:25:04 +00:00

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.

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).

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.

e53ec9745b Updated to work better with the new assembly functions like fuswintr().

a panic if needed.

165dc50b4c This file can be removed now that the stubs functions it contained have

e75becbba3 Initial commit of proper [fs]uword() and associated functions. This

inittodr() and resettodr() will not work.

cf67f29afe * Add a HOSTED_C_C variable, which strips -p', -pg', and
`-nostdinc', and use it when building genassym.

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.

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 *.

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.

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.

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.
