|
20070415 Landisk PCLOCK should be 33.33 MHz, not 50 MHz. (This makes |
3395 |
|
the clock run at correct speed.) |
3396 |
|
FINALLY found and fixed the bug which caused OpenBSD/landisk |
3397 |
|
to randomly bug out: an &-sign was missing in the special case |
3398 |
|
handling of FPSCR in the 'LDS.L @Rm+,FPSCR' instruction. |
3399 |
|
Adding similar special case handling for 'LDC.L @Rm+,SR' |
3400 |
|
(calling sh_update_sr() instead of just loading). |
3401 |
|
Implementing the 'FCNVSD FPUL,DRn' and 'FCNVDS DRm,FPUL' |
3402 |
|
SuperH instructions. |
3403 |
|
The 'LDC Rm,SR' instruction now immediately breaks out of the |
3404 |
|
dyntrans loop if an interrupt is to be triggered. |
3405 |
|
20070416 In memory_rw.c, if mapping a page as writable, make sure to |
3406 |
|
invalidate code translations even if the data access was a |
3407 |
|
read. |
3408 |
|
Minor SuperH updates. |
3409 |
|
20070418 Removing the dummy M68K emulation mode. |
3410 |
|
Minor SH update (turning unnecessary sts_mach_rn, sts_macl_rn, |
3411 |
|
and sts_pr_rn instruction handlers into mov_rm_rn). |
3412 |
|
20070419 Beginning to add a skeleton for an M88K mode: Adding a hack to |
3413 |
|
allow OpenBSD/m88k a.out binaries to be loaded, and disassembly |
3414 |
|
of a few simple 88K instructions. |
3415 |
|
Commenting out the 'LDC Rm,SR' fix from a few days ago, because |
3416 |
|
it made Linux/dreamcast bug out. |
3417 |
|
Adding a hack to dev_sh4.c (an extra translation cache |
3418 |
|
invalidation), which allows OpenBSD/landisk to boot ok after |
3419 |
|
an install. Upgrading the Landisk machine mode to stable, |
3420 |
|
updating documentation, etc. |
3421 |
|
20070420 Experimenting with adding a PCI controller (pcic) to dev_sh4. |
3422 |
|
Adding a dummy Realtek 8139C+ skeleton device (dev_rtl8139c). |
3423 |
|
Implementing the first M88K instructions (br, or[.u] imm), and |
3424 |
|
adding disassembly of some more instructions. |
3425 |
|
20070421 Continuing a little on dev_rtl8139c. |
3426 |
|
20070422 Implementing the 9346 EEPROM "read" command for dev_rtl8139c. |
3427 |
|
Finally found and fixed an old bug in the log n symbol search |
3428 |
|
(it sometimes missed symbols). Debug trace (-i, -t etc) should |
3429 |
|
now show more symbols. :-) |
3430 |
|
20070423 Continuing a little on M88K disassembly. |
3431 |
|
20070428 Fixing a memset arg order bug in src/net/net.c (thanks to |
3432 |
|
Nigel Horne for noticing the bug). |
3433 |
|
Applying parts of a patch from Carl van Schaik to clear out |
3434 |
|
bottom bits of MIPS addresses more correctly, when using large |
3435 |
|
page sizes, and doing some other minor cleanup/refactoring. |
3436 |
|
Fixing a couple of warnings given by gcc with the -W option (a |
3437 |
|
few more warnings than just plain -Wall). |
3438 |
|
Reducing SuperH dyntrans physical address space from 64-bit to |
3439 |
|
32-bit (since SH5/SH64 isn't imlemented yet anyway). |
3440 |
|
Adding address-to-symbol annotation to a few more instructions |
3441 |
|
in the SuperH instruction trace output. |
3442 |
|
Beginning regression testing for the next release. |
3443 |
|
Reverting the value of SCIF_DELAYED_TX_VALUE from 1 to 2, |
3444 |
|
because OpenBSD/landisk may otherwise hang randomly. |
3445 |
|
20070429 The ugly hack/workaround to get OpenBSD/landisk booting without |
3446 |
|
crashing does NOT work anymore (with the April 21 snapshot |
3447 |
|
of OpenBSD/landisk). Strangely enough, removing the hack |
3448 |
|
completely causes OpenBSD/landisk to work (!). |
3449 |
|
More regression testing (re-testing everything SuperH-related, |
3450 |
|
and some other things). |
3451 |
|
Cobalt interrupts were actually broken; fixing by commenting |
3452 |
|
out the DEC21143s in the Cobalt machine. |
3453 |
|
20070430 More regression testing. |
3454 |
|
20070501 Updating the OpenBSD/landisk install instructions to use |
3455 |
|
4.1 instead of the current snapshot. |
3456 |
|
GAAAH! OpenBSD/landisk 4.1 _needs_ the ugly hack/workaround; |
3457 |
|
reintroducing it again. (The 4.1 kernel is actually from |
3458 |
|
2007-03-11.) |
3459 |
|
Simplifying the NetBSD/evbarm install instructions a bit. |
3460 |
|
More regression testing. |
