Changed ispcvt + to report status of compile time switch. + +- release beta 23 -------------------------------------------------------------- + +- removed some files for 386BSD as there is virtually noone outside + using it anymore + +- make pcvt_ioctl.h accept "KERNEL" or "_KERNEL" for NetBSD-current + +- configuration fix: patch from Rafal Boni for pcvt_vtf.c, he writes: + This patch lets one compile pcvt on a system that is lacking XSERVER + and UCONSOLE [or either?] in the config file. I found this while + trying to build a minimal floppy-based test kernel. The problem is + that roll_up and roll_down assume that PCVT_USL_COMPAT is + unconditionally set, and hence muck with parts of the video structure + that are only there if PCVT_USL_COMPAT is set. + (generalized the patch a bit so that fastscroll functionality is + not lost in case of PCVT_USL_COMPAT not being defined. -hm) + +- bugfix: pcvt_ext.c switch_screen() - when switching to a 25 line charset + pure VT emulation screen which has force 24 lines set, then we have + to clear the last line on screen (bugreport from Joerg). + +- added define PCVT_NONRESP_KEYB_TRY for how many times to try to detect + a non-connected keyboard. This was previously set to 100 and + Joerg reports a 5+ minutes delay for a 386 booting without keyboard. + Set to 25 now in the definition. Also made shure the messages in + the corresponding loop display only once. [doreset() in pcvt_kbd.c] + +- updated kbdio utility to include the 7 us delay and added a 'what' command + detect type of MCA motherboard keyboard controller according to + Frank van Gilluwe, "The Undocumented PC", Addison Wesley, pp 273 + +- "Gateway 2000" problem: after some discussion on the NetBSD port-i386 + mailing list about hanging keyboards, Martin Husemann sent in a + patch where each inb(CONTROLLER_DATA) is now preceeded by a + delay(6). This fixed his keyboard problem, the same was reported + from Roland McGrath for his Gateway 2000 keyboard/machine. + +- patch from John Kohl for usl_vt_ioctl() in file pcvt_ext.c, he writes: + This is probably a long standing bug. tsleep() returns ERESTART + if it's interrupted. ERESTART is -1, which means that the + VT_WAITACTIVE call returns from usl_vt_ioctl() with -1, + meaning "not one of my ioctl's". + +- patch from Matthieu Herrb for NetBSD-current (post 1.0) support + +- patch from Joerg for FreeBSD pre-2.1 support + +- added file ToDo in directory Doc + +- fix for Util/Makefile.inc.NetBSD-c from Onno + +- removing unnecessary Trident support code from pcvt_out.c + +- fix from Onno for IST_EDGE in NetBSD-current + +- patch from Thomas Eberhardt to fix the bell frequency and duration setting + for NetBSD + +- some fixes from Onno van der Linden for NetBSD + +- added patch for NetBSD-current from Rafal Boni and Lon Willett + +- added another mega patch from Lon Willett fixing several bugs: + + 1 -- Misc porting changes to deal with NetBSD-current, including + a new Util/Makefile.inc.NetBSD-current. + + 2 -- The Control_R scancodes were being mapped to the Control_L + pcvt keynum. + + 3 -- FASTSCROLL/graphics-mode problem: there was a problem where + switching from a graphics screen to a text screen would corrupt + the text screen's content if it had been scrolling using the + FASTSCROLL code. (The problem is the bcopy() from kernel to + video memory was using the vs[i].Memory pointer as the source, + instead of the vs[i].Crtat pointer). This is fixed in the beta + 21 release by just disabling the fast scroll code for screens + which aren't active. + + The patch I'm sending you re-enables the fast scroll code on + inactive (i.e. in kernel memory) screens, saving a few cpu + cycles. + + 4 -- This is a big one: running multiple X servers was not + really working. The USL handshaking code was a mess (not very + well designed to begin with, but there's not much that can be + done about that). I did manage to get it fairly functional, but + there's a lot of changes. + +- changing example rc.local to take care of good old EGA's + +- fixing support for EGA boards in vt_coldinit() + +- removing vt100 font files from Util/fonts, updated Manifest + +- fixing an obviously longstanding bug in roll_up() / roll_down() which was + triggered by Joergs "Crtat" cleanup mega patch. + +- removing PCVT_FAKE_SYSCONS10 + +- removing duplicate names in termcap entries + +- fixing vt_coldinit: setting variable "color" for mda/hercules and cga + initializing cursor position + +- fixing roll_up() and roll_down() for mda/hercules: mda's have ALWAYS + just one page of memory, original hercules boards too so they + can NEVER use the fastscroll option. SOME hercules are somehow + enhanced in that they support 2 pages. pcvt now just supports + one page hercules/mda! + +- made cleanups to 8x14 high and 8x8 high fonts: adjust the 5 scanline + characters to adjust with the corner characters from the low fonts + +- applying patch from Joerg which fixes some bugs: + + writing to a tty containing an X server resulted in some stange + behaviour depending on the opsys and opsys version used + + the init code preserving the screen contents and cursor shape + can only be done on boards allowing the reading of + several crtc registers + +- removed bcopyb declaration from pcvt_hdr.h for FreeBSD 2.1 + +- another patch from Lon Willett (willett@math.utah.edu), he writes: + + 1 -- Very minor: One of my previous changes didn't get merged + into "pcvt_out.c"; the caclulation of ws_row doesn't account for + "force24" at one spot. It's easier to just set it from + screen_rows anyway, unless there's something that I didn't + understand happening here. + + 2 -- Debugging stuff: I don't know if you care to add it, but I + found it useful, so I left it in. I rearranged the + PCVT_SHOWKEYS code a little, and added a few lines to show + keyboard commands and responses, with special delimiters. + [file: pcvt_kbd.c] + + 3 -- "kcon" utility enhancement: I added a "-R" switch to kcon + to do a KBDRESET ioctl. [file: Util/kcon/kcon.c] + + 4 -- KBDRESET-ioctl bug: the code was trying to read kbd + responses without an spltty(), so naturally it would fail, since + pcrint() was grabbing the ACKs. [file: pcvt_kbd.c] + + 5 -- update_led() makes kbd hang: the problem here is that + update_led() makes the keyboard generate two KEYB_R_ACK + responses, and one of the interrupts sometimes gets lost when + there is a lot of other I/O happening. See the comment in the + code. My fix seems to work for me, but you may want to handle + it some other way. It would probably be quite reasonable to + check for lost interrupts periodically anyway, whether + update_led() has been called or not. [file: pcvt_kbd.c] + + (NOTE: item 5 has been disabled because it causes older + FreeBSD's to panic because of the timer queue not being + initialized at the time called. -hm) + +- partly rewrote doreset() in pcvt_kbd.c to enable boot procedure to proceed + if no (PC) keyboard is found. The current behaviour and implementation + is subject to change. + +- patch from Thomas Gellekum to Util/keycap/keycap.src + +- minor modification to main.c in Util/set2061 + +- patch from Onno and John Kohl to make pcvt beta 16 work on NetBSD current: + 1. pcvt_conf.h + _real_ 1.0 ===> NetBSD1_0 == 1 + current 1.0 (1.0A) ===> NetBSD1_0 == 2 + 2. pcvt_hdr.h + Put pcvt_conf.h before _all_ the #ifdef PCVT_*. This way + the #ifdef NetBSDx_y stuff can do its work. + +- size of PCVT_BURST was still reported as 1 for FreeBSD 2.0, fixed + +- made some adjustments for FreeBSD 2.0 in Util/vgaio + +- Another patch from Joerg for FreeBSD 2.0 + +- included vgaio, kbdio and set2061 into the outer Makefile, this programs + are build and cleaned but don't install anything. + All program's in the Util dir should now cleanly make <anything> ... + +- enable 132 column support for Trident TVGA8900CL, some NetBSDisms + +- addend patch from Joerg for pcvt-320b7 to fix FreeBSD 2.0's ttymalloc's + encapsulation into #if's. Also new keycap.src entry. + +- fixed keyboard status/LED not updated on soft reset emulator + +- on 23rd of December i had some spare time, so i added some demos to the + Util/demo directory as well a a time-killer program (playvt) to view + some of the VT animations and a christmas animation i got from Joerg. + +- added a new utility set2061 to program the clock generator on my S3 based + ELSA Winner VGA board. This eventually lets me use 132 columns on this + board, because i'm now able to program the clock to generate 40MHz + on clock output #2. + +- debugged winsize patch on FreeBSD 1.1, line discipline open init's the + queues, winsize initialization must happen after line disc. open! + +- got a bunch of NetBSD PR's from J.T. Conklin: + + PR #214: PCVT treats ctrl-shift exactly like shift for most characters. + (fixed by Lon Willet's Mega Patch described below -hm) + + PR #399: If you define PCVT_META_ESC when builting PCVT, Meta-Return + sends 0x8d instead of ESC RET. + (fixed by applying the patch from Bill Sommerfeld. -hm) + + PR #400: pcvt sometimes gets confused about window size + (fixed by applying the patch from Bill Sommerfeld. -hm) + + PR #404: Meta-Control-Space broken with PCVT_META_ESC and PCVT_NULLCHARS + (put into "BugList" file, no solution yet .. -hm) + + PR #488: pcvt can loose keyboard control if you start an xserver from + an xterm + (already fixed by a patch from John Kohl, see below -hm) + + PR #580: NetBSD i386/pcvt bugs/enhancements; fixes included + (already integrated the patch from Lon Willet, see below -hm) + +- on coldinit, if FAT_CURSOR is defined, the old large blockcursor is used + +- enhanced the vgaio output in an attempt to make 132 column mode work + for my S3 board .... + +- applied patch from Thomas Gellekum: install instructions for FreeBSD 2.0, + patch to fontedit to compile under FreeBSD 2.0, an addition to + keycap.src and a fix for kbdio + +- changed installation instructions to reflect recent changes, removed + instructions for FreeBSD 1.0 and added instructions for FreeBSD 2.0 + +- upgraded all utilities version strings to 3.20 + +- new example of rc.local + +- changing timeout()/untimeout() function parameter type to TIMEOUT_FUNC_T + definition in pcvt_hdr.h + +- changed install instructions to reference Etc dir instead of Doc dir for + several files which were moved from Doc to Etc. + +- new parameter -d for the cursor utility, updated cursor manpage + +- applying a patch from Lon Willett, willett@math.utah.edu which fixes + several bugs and provides some enhancements. Lon writes: + + 1 -- The displayed cursor is not updated during kernel I/O, + because async_update() doesn't get called. This is merely ugly + while the system startup messages are being displayed, but it is + positively annoying when using the kernel debugger. + + 2 -- CONTROL-SHIFT-<KEY> is taken to be the same as SHIFT-<KEY>. + It should be interpretted as CONTROL-<KEY>, or even have its own + binding. One of the lines below fixes it in the former way. + This is especially bad (i.e. clearly buggy) when I type + CONTROL-SHIFT-<6/^> to get a "Control-^", and instead get a "^". + + 3 -- The "special" region at the bottom of the screen, i.e. the + function-key-labels/status-line in HPVT mode, and the blank line + in FORCE24LINES mode, do not get properly cleared/updated. + + 4 -- When switching screen sizes/modes, the FORCE24LINES setting + is not always handled. + + 5 -- The PCVT_VT220KEYB functions are missing some features. + The control key settings are bug fixes; they apply only if + system function key labels are on, and match the labels. The + shift key definitions are enhancements. + + The new keys (previously undefined) are: + + Control-F1 -- toggle 80/132 columns + Control-F2 -- soft reset emulator + Control-F3 -- toggle force 24 lines mode + Control-F4 -- toggle keyboard debugging + + Shift-F1 -- select screen 4 + Shift-F2 -- select screen 5 + Shift-F3 -- select screen 6 + Shift-F4 -- select screen 7 + Shift-F5 -- select (current screen - 1) + + 6 -- [Enhancement] The initial startup screen is cleared, and + the screen gets cleared when changing modes/sizes. I don't like + this. I want a chance to see bootstrap loader messages, and I + also want the command "scon -d/dev/ttyv0 -H -s28" in my + rc.local, but then I lose various messages from daemons, etc + (which aren't always logged to syslog). So I have fixed the + code so that it tries to preserve the contents of the screen + when starting up, and when changing modes/sizes. + + 7 -- [Enhancement?] I added code to preserve the initial cursor + shape at startup. This isn't really necessary, since the + "cursor" command can be used to set it to your preference; but + it seems like this is the preferable policy to use for the + default. + +- applying patches from Onno van der Linden and Martin Husemann: adding + support for post 1.0 NetBSD-current and adding PCVT_NO_LED_UPDATE + +- patch from Joerg Wunsch: support for FreeBSD 2.0 and better support + for serial console coexistence + +- bugreport from Michael Havemester regarding PCVT_NOFASTSCROLL: it was + not enabled in pcvt_vtf.c, fixed. + +- renamed pcvt_disable_intr and pcvt_enable_intr to PCVT_DISABLE_INTR and + PCVT_ENABLE_INTR (Joerg) + +- attempt to automatically compile time configure in pcvt_conf.h, how + does FreeBSD do this ? should work for NetBSD (from Onno v.d.

Burditt, gordon@sneaky.lonestar.org) + +- modified Makefile for Support/ispcvt to copy it for installation instead + of moving it .. + +- renamed /usr/share/misc/keycap -> /usr/share/misc/keycap.pcvt to + avoid nameclash with same file for codrv (Gordon Burditt) + +- security bit no longer ignored when initializing keyboard (see #define + PCVT_USEKBDSEC in pcvt_hdr.h, suggested by Terry Lambert) + +- cpufunc.h include made only for NetBSD (Gordon Burditt) + +- switch statement in pcvt_drv.c removed for 386BSD (Gordon Burditt) + +- Trident cursor size bug removed + +- keyboard initialization for ddb + +- added support for cursor on/of switching, screensaver and DECTCEM + +- removed explicit Hercules support, MDA = Hercules in this context now + +- patchkit from Joerg Wunsch (kbd-overlay malloc, scroll_sleep, clip fix) + +- ispcvt now installed into /usr/sbin + +- removed PCVT_NETBSD08 and PCVT_NETBSDCU, intro of PCVT_NETBSD + +- implemented 132 column operation for wd90c11 chipsets + +- PCVT_PREPATCH022 renamed to PCVT_NEEDPG + +- INSTALLATION.NetBSD written + +- DEVICE in kcon makefile changed from /dev/console to /dev/ttyc0 + +- new keyboard code in pcvt_kbd.c from NetBSD current + +- new /etc/rc.local script in INSTALLATION + +- implemented 132 column operation for et4000 chipsets + +- detection of super vga chipsets as a prerequisite for 132 col mode + +- switched to memory mapped virtual screen operation, configurable no. of + virtual screens, virtual screens now also on MDA and Hercules boards + + +Changes 2.10 -> 2.20 June 1993 +-------------------------------------------------------------------------------- + +- added new option -a to scon to get the video adaptor in scripts + +- support for NetBSD-current, define PCVT_NETBSDCU to enable it + +- Support for NetBSD 0.8, define PCVT_NETBSD08 in pcvt_hdr.h to enable it. + +- Change Support/Makefile to use <bsd.subdir.mk> instead of <bsd.prog.mk> + +- Font editor for the EGA/VGA font-files added to support the design of new + fonts. One will need Zeyd M. Ben-Halim's ncurses library to compile it, see + file README.FIRST for information where to get it + +- Doc/INSTALLATION upgraded + +- Terminfo entry added to support Zeyd M. Ben-Halim's ncurses port + +- ispcvt is now installed in /sbin to have it at boottime if /usr is not + yet mounted. + +- applied a patch which prevents CAPS LOCK, SHIFT LOCK, and SCROLL LOCK + from being repeated (causing i.e a flashing CAPS LOCK led while + holding CAPS LOCK key down). + (diff from Gordon L. Burditt, gordon@sneaky.lonestar.org) + +- merging patches to support the pccons-model of X11 server support + (diff from Joerg Wunsch, joerg_wunsch@uriah.sax.de) + +- file pcvt_drv.c routine pg() enclosed in "#ifdef PCVT_PREPATCH022" to solve + multiple defined symbols beginning with patchkit 0.2.2 + (reported by Marko Karppinen, dreamer@purkki.apu.fi) + +- added british keycap entry into keycap source file + (from Andy Duplain, duplain@rtf.bt.co.uk) + + +Changes 2.00 -> 2.10 March 1993 +-------------------------------------------------------------------------------- + +- detecting the presence of video boards has been changed to ask the + BIOS "equipment byte" in the RTC-CMOS ram what's installed. this caused + many discussions but solved also many problems .... + +- driver name changed from "pc" to "vt" for multiple driver coexistence + (diff from Joerg Wunsch, joerg_wunsch@uriah.sax.de) + +- new devicenames recommended for showup in utils like "ps" + (many people suggested that ..) + +- new location for manual pcvt.0 + (diff from Joerg Wunsch, joerg_wunsch@uriah.sax.de) + +- new demo file "sgr.vt" to show available graphic renditions + +- intro of Doc/ChangeLog (this file) + +- fixed bug in Support/keycap/Makefile + (diff from Gordon L. Burditt, gordon@sneaky.lonestar.org) + +- make vttest (main.c) compile after applying patchkit-beta2 + +- screensaver fixed by Joerg Wunsch + +- screensaver now compiled in by default + +- made recognition of CONTROL-ALT-DELETE an optional #ifdef'ed feature + +- added sgr-conversion table for MDA adaptors + +- fixed sgr-conversion table for VGA monochrome environments + +- added support for using the kernel debugger + (diff from Bruce Evans, bde@runx.oz.au) + +- fixed several bugs regarding monochrome environments in pcvt_sup.c + +- fixed bug in scon preventing one from piping output though more + (reported by Gordon L. Burditt, gordon@sneaky.lonestar.org) + +- display current screen number in HP-mode in the bottom right of screen + +- changed names of all #define-able compile time options to start with + "PCVT_" for easy identification and installation into the kernel config file + +- applied another pcvt_kbd.c patchkit from Bruce Evans, bde@runx.oz.au. he + writes: + + These fixes are mainly related to ddb. sgetc has a weird interface that + has caused some bugs, and it was too easy for ddb to reenter itself. + + 1. Don't use char for keypad2num, char might be unsigned. Space is not + important since the array is small. + + 2. Don't use u_short for n. + + 3. Change some 0's to NULLs. + + 4. sgetc must not return NULL for the !noblock case. Only callers with + noblock set check for the null pointer. When the kernel follows a + null pointer, I think page 0 is sometimes mapped in so nothing bad + happens. The kernel panics if the page is not mapped in. + + 5. Reentrancy fix. The debugger really ought to check for reentrancy + itself, but the driver still needs to return early after the + debugger returns, so that it doesn't return a junk ESC from + ctrl-alt-ESC. + + 6. xlatkey2ascii may return NULL too. + +-------------------------------------------------------------------------------- |
