2014-07-22Use MI rasops_cmap, instead of MD-defined ANSI colormap.Kenji Aoyama
Note about workaround for 8bpp frame buffer: Current LUNA wscons touches only first 4 planes (plane #0-#3), but other program (e.g. mlterm-fb) can use all 8 planes on an 8bpp frame buffer. When such program exits, it may not clear all planes, so there may be some visible garbage data on the other 4 planes (plane #4-#7) when we use default 256 rasops_cmap directly. We should manage all 8 planes on LUNA, but that will be too much overhead for 16 colors wscons. So, by repeating 16 colors in 256 colormap, we can ignore the values on the other 4 planes. ok miod@
2014-07-21boot(9): Reduce annoying style diffsMasao Uebayashi
- Always use either: ((x & RB_XXX) != 0) or ((x & RB_XXX) == 0) in boolean context (mostly if (x), or x ? y : z) - prom_halt() in alpha is confirmed to take int as boolean Converted by coccinelle. No functional change intended.

2014-07-10Set cold to 1 before executing the DVACT_POWERDOWN handlers when halting orMartin Pieuchot
rebooting a machine, like it is done in the hibernate case. At least some USB host controller drivers rely on this to busy way instead of sleeping. Avoid a panic on macppc with an uhci(4) cardbus plugged in. ok deraadt@, uebayashi@
2014-07-10boot(9): More comment removal about cold/savectx() missed in previousMasao Uebayashi
2014-07-10boot(9): Remove comments about RB_*, "cold", and savectx()Masao Uebayashi
Again remove slightly different comments to reduce diffs. These will be re-added once boot() become MI and its specification is clearly re-defined. OK miod@
2014-07-10boot(): Remove comments about RB_TIMEBAD to reduce diffsMasao Uebayashi
RB_TIMEBAD is documented well enough that the comment is not needed. sparc64 does slightly different and its comment is left with XXX. OK deraadt@ miod@
2014-07-10boot(): Unify declarationsMasao Uebayashi
OK deraadt@
2014-07-01Replace the assembly 88100 FPU imprecise exception code (mostly triggered byMiod Vallat
denormal results) with C code using softfloat to correctly round the inexact results in the best possible way according to the current rounding mode. No functional change intended, and this assembly code was surprisingly almost non-buggy, as opposed to the precise exception code replaced a few weeks ago; still an improvement as this replaces 900 lines of arcane assembly with 90 lines of understandable C code.
2014-06-18Update comment; there seems to be no PC-9801 extension board slot onKenji Aoyama
'original' LUNA-88K.
2014-06-09Replace the unmaintainable assembler code responsible for 88100 precise FPUMiod Vallat
fault handling with a C wrapper around the softfloat code, as already done for 88110 kernels. As a bonus, attempting to read or write FPU control registers but fcr62 and fcr63 in userland will now correctly signal an illegal instruction, instead of leaving the destination register unchanged and pretending nothing bad happened. Be sure to rm m88100_fp.d in your kernel compile directory after updating your tree.
2014-06-07Modify to ANSI-style function declarations. No binary change.Kenji Aoyama

2014-06-03Better comment for `faulty address'.Kenji Aoyama
2014-05-31Revert previous diff setting cold to 1 on shutdown because it breaks machineMartin Pieuchot
with softraid(4) disks. softraid(4) is the last real consumer of the doshutdownhooks(9) API and it is not trivial to convert its hook to a DVACT_POWERDOWN handler since the latter does not allow to sleep.

2014-05-08The pcexmem(4) and pcexio(4) should be attached on LUNA-88K2 only.Kenji Aoyama
Actually, there seems to be no PC-9801 extension board slot on 'original' LUNA-88K. ok miod@
2014-04-22Unify the model name to LUNA-88K{,2}, that is considered theKenji Aoyama
`official' name. ok jmc@ miod@
2014-04-16Add generic driver for "NEC PC-9801(*) extension board slot" onKenji Aoyama
LUNA-88K. LUNA-88K{,2} has one or two slot(s) that can attach the extension board designed for PC-9801. This driver provides dedicated mmap(2) and capability for waiting specified interrupt on that slot so that we can use the extension board from userland program. (*)PC-9801 is a Japanese popular personal computer, mainly used in 1980-90's. (see http://en.wikipedia.org/wiki/NEC_PC-9801) ok miod@, and man pages jmc@

2014-03-29It's been a quarter century: we can assume volatile is present with that name.Philip Guenther
ok dlg@ mpi@ deraadt@
2014-03-13get rid of the assumption that the head of the alldevs list is theDavid Gwynne
"mainbus" device. this breaks when mpath is enabled because it attaches before mainbus and therefore takes the head position. have autoconf provide device_mainbus() which looks up mainbus_cd, and use that instead. discussed with deraadt who just wants mpath stuff to move forward despite there being many ways to shine this particular turd.
2014-02-23Try and load /etc/random.seed before attempting to load the kernel.Miod Vallat
Bump version.
2014-01-30Add missing 'stand' directory in order to work 'make build' and 'makeKenji Aoyama
install' properly. ok miod@
2014-01-29Add rnddata[] placeholders to make boot block build again, same asKenji Aoyama
other platforms. ok miod@
2014-01-26Attempt to make user changes of keyboard layout a bit more `sticky' on wsmuxMiod Vallat
kernels: - keyboard drivers will now tell wskbd if the keyboard layout they ask for is a default value, or a value they are 100% sure of (either because your kernel has a XXXKBD_LAYOUT option, or because the driver can tell the keyboard layout, e.g. by the country code on USB keyboards which provide it, such as Sun's) - when attaching a keyboard with a non-default layout, the layout will become the default layout of the mux for new keyboard attachments if the mux doesn't have a layout set already. - when changing the keyboard layout of a particular keyboard with an ioctl (i.e. using kbd(8) or wsconsctl(8)), the layout will become the default layout of the mux for new keyboard attachments. ok mpi@
2014-01-19Initialize ci_randseed better using arc4random() + a trick. Remove theTheo de Raadt
libkern srandom() API since it is not suitable for this use. ok kettenis miod
2014-01-15Add WSDISPLAYIO_SETGFXMODE ioctl on LUNA's frame buffer.Kenji Aoyama
This ioctl changes `pseudo' frame buffer depth, in order to use color wscons and monochrome X server both. Also need to some luna88k-specific initialization in xenocara/driver/xf86-video-wsfb/src/wsfb_driver.c.

2014-01-03KNF, update comments, and delete LUNA(m68k) specific DIPSW comments.Kenji Aoyama
No functional change.
2014-01-02Add primary support for LUNA-88K 4bpp/8bpp frame buffer.Kenji Aoyama
This brings color support on LUNA's wscons. And, with the help of recent development version of 'mlterm-fb' (frame buffer version of ports/x11/mlterm), graphic images can be displayed in 16/256 colors on the screen. Thanks to arakiken, the original developer of mlterm! This diff is based on NetBSD/luna68k work: http://mail-index.netbsd.org/source-changes/2013/12/28/msg050266.html Need more work to coexist with the monochrome X.Org server. "go ahead!" miod@
2013-12-30Correct initialization of Bt458, used in LUNA's 8bpp frame buffer.Kenji Aoyama
According to the manual, the address register does not automatically increment when we access to the control registers. Also we disable overlay planes, because we do not use them. This diff should be one of preliminaries for upcoming colored wscons on luna88k. ok miod@

2013-11-16Re-organize luna88k rasops om_{copy,erase}{cols,rows} by using oneKenji Aoyama
generic function, based on hp300/dev/diofb_mono.c. This also fixes `screen is not updated when delete a character if it is on the middle of a 32-bit word of the frame buffer' problem. "Go for it!" miod@
2013-11-16Allow initial device mappings (from pmap_table) to be backed up by BATC.Miod Vallat
Use this on luna88k to map the bitmap planes of the frame buffer used by the driver. 10% speedup under X.
2013-11-16Allow ddb to be entered from the keyboard, if glass console and ddb.console=1,Miod Vallat
with ctrl-alt/zenmen-esc. Tested on three different keyboard models (compact black, JIS, and full-sized) by aoyama@ and me.
2013-11-13Do not map frame buffer resources the kernel doesn't use; only keep theMiod Vallat
lowest bitmap plane, and a page per plane to be able to probe the frame buffer depth. Saves an insignificant amount of kernel memory (about 4KB), still worth doing. ok aoyama@
2013-11-12We always make symlinks to 'machine' and 'm88k' to compile.Kenji Aoyama

2013-11-05Replace direct references to p_size, p_offset and d_secperunit withKenneth R Westerback
DL_[GET|SET]PSIZE(), DL_[GET|SET]POFFSET(), DL_[GET|SET]DSIZE() in order to get|set correct value that includes the high bits of the value.
2013-11-03Even saner kernel layout, so that .rodata can be batc mapped by a read-onlyMiod Vallat
dbatc. Add batc mapping support for 88110 systems as well.
2013-11-02Use a linker script to align .data to a BATC boundary as well, so that noMiod Vallat
DBATC may span over parts of .rodata.
