leo 89532d8b32 Introduce NO_PHYS_NETWORK as a define in the FALCON kernel. This define is 
used to turn off the vlan, bridge and pppoe pseudo devices and the NETATALK
protocol.

aymeric 84ccd9ee4b call grfcc_probe() and viewprobe(), even when we are not the console. 
This fixes a panic when using a serial console and wsconscfg.
(The monitors list wouldn't be initialized in grfabs.c)

scw 2a7a3cc2f8 In the _EXCEPTION_EXIT macro, don't use r24 until we've finished 
accessing the kernel stack, since a TLB miss on the kernel stack
will result in r24 being trashed.
Also clear the ES_CRITICAL flag just before returning to the
previous context.

jdolecek ed2badbd21 make vers.c depend on ${SOURCES} and remove .PHONY tag for it, so that it 
would only be regenerated if any of the input files changed

manu 9d459610ba When the serial port was not checked in hpcboot on hpcarm, writing to 
/dev/ttyS0 crashed the kernel. This is because sacom_filltx uses some
uninitialized static variables. Pulling the salues from softc instead
fixes the problem (this is what was done before the drver was moved
from /sys/arch/hpcarm to /sys/arch/arm, anyway).

thorpej 556a752996 Build a .gdbinit in the kernel build directory. The new .gdbinit 
will source all of the system-provided gdb scrips in sys/gdbscripts,
as well as any files specified by the user in the GDBINIT make var.

scw b02c328efd Track adjacent movi/shori instructions with the same destination register 
so we can print the accumulated value.

Print symbols, if possible, when decoding "pta" branch targets, and
"movi"/"shori" accumulated values.

mjacob e2f3e02af9 Do not enable interrupt driven mailbox commands for non-FC scsi. 2002-09-01 22:30:09 +00:00
martin 1caaa903fa If the peer did not answer LCP echo requests in-time, but we got user 
data through within the last LCP keepalive interval, do not count this
as a keepalive failure.

Addresses parts of kern/17723.
 2002-09-01 18:54:12 +00:00
martin adb5933cbb Apply patch from Todd Vierling in PR kern/17665: 
remove a test that has been obsoleted by the authentication failure
counter - enter slow retry mode always, not only if we already transfered
data successfully (the test was designed to disable retries when the
initial authentication setting was not correct, the auth failure counter
does this job better).

martin ac83580ea9 Add an option PPPOE_TERM_UNKNOWN_SESSIONS to forcefully disconnect sessions 
we don't know anything about with a PADT packet.

Use with care, this is pretty dangerous and will kill all userland PPPoE
implementations. Therefore it is not enabled by default nor added as
a commented out option to GENERIC kernels.

But it is highly usefull if you have a fixed IP, an ISP that does not use
LCP echo requests for link monitoring and you want to recover quickly after
a crash or otherwise ungracefull disconnect.

itohy f89823c1f8 Save 1-4 instructions on all cases except for the ret=0 case. 
This is probably the last version from me. :)
You are welcome to speed it up, of course. :)

Here's a benchmark on SH-4 200MHz.
9.2% faster if all the cases occur evenly.

scw f387921c31 Move registers r10-r13 over to the Caller-saved set, at least as far 
as intrframe and trapframe are concerned.

According to the ABI, only the low 32-bits of these registers are
guaranteed to be preserved by the callee. Therefore, we need to
preserve all 64-bits of them in the interrupt trampoline.

takemura 6a286a4f2a BUGFIX: WSDISPLAYIO_SVIDEO and WSDISPLAYIO_GVIDEO don't work. 2002-09-01 11:38:29 +00:00
takemura e00064b3e0 Fixed again. Rev 1.7 was incomplete and this device did't work for long time. 2002-09-01 10:45:38 +00:00
bouyer 3a7aeb79ca nfs_doio(): handle the case where nfs_writerpc() returned error != 0. 
Fix kern/18125. OK'd by thorpej and chs.
 2002-09-01 10:39:38 +00:00
scw 75c81c5275 Blah, some of the larger operands could overflow the "opstr" buffer. 
Bump the size of all of them to be on the safe side.
 2002-09-01 10:07:25 +00:00
scw d73a178b6b Output a new-line character after disassembling the opcode. 2002-09-01 09:18:52 +00:00
scw 5938c04bbe Yay, single-step now works. 
Also do a wee bit tidying up.
 2002-09-01 09:01:33 +00:00
scw 1398cd2898 Verify that the lowest 4 bits of the opcode are zero before disassembling. 
According to the docs, opcode 0x6ff4fff0 is gauranteed to generate
a RESINST exception on all implementations, so disassemble it as "illegal".

scw 4c7d945594 A full SHmedia disassembler for ddb(9). 
ToDo:
 - Symbol support (can't test as yet, due to lack of symbols),
 - Take notice of adjacent "movi/shori" instructions in order to display
   the resulting 32/64-bit value, with symbol lookup if possible.

scw 63fee282ed Always panic in the default/dopanic case, even if kdb_trap() returns. 2002-08-31 09:41:05 +00:00
scw 9c10dc5c22 If DEBUG is defined, enable Cayman's NMI button. 2002-08-31 09:30:02 +00:00
scw da6c509ffa Pick a better T_NMI code. The previous one clashed with T_AST|T_USER. 2002-08-31 09:25:53 +00:00
scw c2aa4b74c8 Don't use "Branch Likely" for the NMI case. 2002-08-31 09:25:24 +00:00
scw 9a6575c7df Add T_NMI. 2002-08-31 09:12:59 +00:00
scw d7dbb0862d Deal with NMIs by jumping through the normal trap() code path. 
At the very least, this will dump the machine state. At best,
we get into ddb().

This provides a useful way to regain control using an NMI button
if the cpu decides to spin at a high ipl.
 2002-08-31 09:11:56 +00:00
scw 17746914f0 Small simplification to the splx() code path when dealing with soft 
interrupts, and fix a couple of nits in the generic soft interrupt code.

Soft interrupts now work.

scw 60bff6ed9c Make sure to sign-extend PTEH/PTEL values before writing to the TLBs. 
Make sure to zero-extend PTEH/PTEL values before comparing with TLB entries.
Don't use the two LSBs of CTC when choosing a "random" TLB entry to replace;
seems like these bits are always zero on this CPU.
 2002-08-30 13:54:16 +00:00
scw 7da5ef1b84 Delete the CPU_CTB1 option; it was never used. 
Add the SH5_INTC_IRL_MODE_INDEP option, to correctly configure
the interrupt controller for Cayman.
 2002-08-30 11:25:09 +00:00
scw 877f6b7143 Add some options: 
- SH5_SIM, as we're targetting the simulator.
 - KERNEL_IPT_SIZE, as we want to reduce startup time.
 - DDB. Yes, DDB inside a debugger/simulator. :)
 2002-08-30 11:23:12 +00:00
scw aaa2f7e5ca When running on the simulator, assume there is 16MB of "RAM". This 
greatly reduces startup time.
 2002-08-30 11:06:03 +00:00
scw 1fd693d5b5 In the IRL1 interrupt handler, you need to read the Interrupt 
Source Register#0, Steve. Not the Board Operating Mode register. Duh.
 2002-08-30 11:03:25 +00:00
scw de63e7f1e4 Swap the IRL numbers for FEMI and SUPERIO, after reading the Cayman 
docs a bit more closely...
 2002-08-30 10:59:39 +00:00
scw 5cc4fe3194 Slight tweak to how the sm(4) driver attaches to superio. Also, just 
use the regular bus tag for sm(4) instead of superio's "special" ISA
bus tag.
