jimke@microsoft.UUCP (Jim KELLY) (12/18/90)
At the end of this post is a patch to Thomas Roell's X386 server that will
let you build and run X386 on SCO Unix System V/386 3.2. Sorry for the
large post but I have no publically available node to put this on.
To install this you need the X11R4 sources up to fix-18 PLUS Thomas Roell's
November 8th X386 sources/patches. Follow all the instructions given to
setup the ix386 version. Apply the patch below. I have only built this
using gcc. Check the README.SCO file for problems I had with other
compilers.
The SCO version has some minor flaws at present. But then again the OS
and development system do too.
-- I have only tested this with a Microsoft serial mouse. The serial port
usually resides at /dev/tty1a so update the Xconfig file before you
start the server. Remember to set up your display/card paramters too.
-- The screen may go blank after stopping the server. Hit enter a couple
times or run 'clear'.
-- If you have an ET3000 you will need an OS with version 3.2.1 or greater.
ET4000 should be OK with 3.2.0 but I haven't tested it.
-- The mouse buttons are flip-flopped. Use xmodmap to fix this.
-- You cannot switch to a different virtual terminal using <Alt><F?> or
any other key combination.
-- No shared library support unless you have the newest DevSys, 3.2.2.
-- The CAPS and NUM lock work but don't light up.
-- The hot key combination <Ctrl><Alt><Bksp> will kill the server with no
questions asked.
-- Check mit/README.SCO for more details.

+ The following is an extensive explanation of changes to the X11R4
+ sources in order to run in on SCO UNIX System V/386 3.2.
+
+ The starting point was patchlevel 18 plus changes done for ix386 by
+ roell@lan.informatik.tu-muenchen.de. It was not too difficut to modify
+ for SCO. roell did most of the work. roell uses the terminology
+ STREAMS pipes for local IPC, but the server still uses the STREAMS
+ psuedo-ttys (ptm/pts) rather than the pipe driver (sp).
+
+ The compiler I used was gcc. The SCO development system contains two
+ compilers, cc which is an ANSIish Microsoft C 5.1 port and rcc which
+ is the AT&T pcc-based compiler. I'll discuss the other compiler
+ attempts below.
+
+ I added an SCO specific file
+ ./server/ddx/at386/sco.h
+
+ There has been quite a lot of press about binary compatibility among
+ the System V/386 3.2 Unixes. Let's set the record straight that this
+ piece of software compiled for SCO will only run on SCO Unix. (Not to
+ mention software that uses some of the Xenix or security system
+ calls).
+
+ First of all we must access the system console so that we can map
+ screen memory into our virtual space, ring the bell and play with the
+ lights on the keyboard. We must also map I/O ports because they are
+ just as protected. To open the system console you open your tty.
+ Typically you open "/dev/tty" which gives you a handle to your
+ controlling tty. The server has a problem with this becuase before
+ execing the server, xinit calls setpgrp() which loses the controlling
+ tty. Opening "/dev/tty" fails. Now in the server I get my real tty
+ name via ttyname() call setpgrp() then open the tty.
+ ./clients/xinit/xinit.c
+ ./server/ddx/at386/screen.c
+
+ We have a handle to the console. To move into graphics mode an
+ KDSETMODE ioctl is sent to the console. How is screen memory mapped.
+ There are three ioctl's documented in the System Administrators
+ Reference and release notes that claim to do this.
+ KDMAPDISP - always causes the kernel to panic.
+ MAPCONS - maps the screen memory, the size of which is defined by
+ the mode we are in. Must switch to a graphics mode before
+ or else we won't map all the memory.
+ MAP_CLASS - maps the screen memory and IO port based on the kernel
+ configuration in /etc/conf/pack.d/cn/class.h. The argument
+ to the ioctl is a string describing the type of device. I
+ used "SVGA" because the screen must map into 128K of CPU
+ addressable memory and MAPCONS only maps 64K. MAP_CLASS
+ only works on 3.2.1 and above. If this ioctl fails I
+ revert to MAPCONS. But if your VGA driver needs to address
+ > 64K (et3000), then you must have 3.2.1 or greater.
+ ./server/ddx/at386/vga/vga.c
+
+ KDMKTONE is not supported. You need KIOCSOUND to ring the bell. It
+ takes an explicit call to both start and stop the bell. Because we
+ need < second precision and to avoid nap(), I used select() and
+ specified zero file descriptors.
+ ./server/ddx/at386/keyboard.c
+
+ I tried adding a VGA driver for my SuperVGA card, Video7 VRAM. There is a
+ limitation with this card that won't allow it to work with the Nov 8
+ version of the server. You cannot have separate read and write pages.
+ The bitblt code sets the read page, then the write page and then
+ does the blite. With the VRAM you would have to reset the page before each
+ set of read/writes. Since this would take minor surgury on the server I
+ just went out and bought an ET4000 card.
+
+ I had to modify /boot to even get the machine to boot. It seems the
+ VRAM's have some ROM pointed to by int 6d. The old /boot does not move
+ the 6d vector segment from E000 to C000 like it does the other video
+ vectors (10, 1f, 43). There is OLIVETTI code for this so I assume the
+ cards would work on those architectures. I have a Compaq.
+
+ Had other problems with my ET4000 card which is an Orchid Pro Designer
+ II w/1M. Whenever the server switched modes the VGA registers would
+ get hosed. There must be some compatibility problem with the vga
+ driver and these cards. Don't know if it effects all ET4000 cards or
+ not. Since one of the server's last duties is to switch to text mode,
+ I had to hand reset the VGA registers in ./server/ddx/at386/screen.c.
+
+ sin() and cos() seemed to screw up the stack. This seems to be a known
+ bug with _ftol() that is fixed in the next rev of the DevSys. In
+ ./lib/X/XlibInt.c I have redefined _ftol() and it either fixes the
+ problem or moves it somewhere else.
+
+ Had a problem with large amounts of data thrugh the IPC for the
+ STREAMSCONN server. This was a bug in _XWriteV in ./lib/X/XlibInt.c.
+ The routine was not simulating writev quite correctly. The function
+ has two nested loops. If the "write" inside the inner loop failed, it
+ only broke out of the inner loop. It should return immediately. I
+ guess it is possbile for one "write" to fail and later "write" to
+ succeed within the same function. Data gets written twice or not at
+ all. I submitted a bug report to expo for this.
+
+ Next change was to the all important xterm. I used /dev/ttyp? for
+ psuedo-termianls rather than the STREAMS tty, /dev/ptmx. Here in lies
+ the second major snafu of SCO I've found. xterm opens "/dev/tty" to
+ read the tty settings. Under certain conditions this open causes the
+ kernel to panic. I use twm as my window manager and like to use its
+ menus to start new xterms. The controlling tty for twm is /dev/ptmx
+ because xinit loses the the controlling tty and twm picks up /dev/ptmx
+ to use it for IPC with the server. When twm starts an xterm, xterm
+ inherits this controlling tty. When xterm goes to open "/dev/tty"
+ (remember opening /dev/tty returns a handle to your controlling tty),
+ the kernel panics. Could it be that the /dev/tty driver does not
+ specify a clone open when it redirects the open to /dev/ptmx
+ (/dev/ptmx is a clone driver). I don't know, but leaving out the open
+ fixes the problem and you end up with a working xterm. Roell has left
+ this code out as well for some reason.
+ ./clients/xterm/main.c
+
+ I have been unsuccessful at creating shared libraries. This is a known
+ problem with the SCO DevSys 3.2, one which is fixed in the SCO DevSys
+ 3.2v2.0 -- The Sequel.
+
+ The build was done using 'make BOOTSTRAPCFLAGS=-DSCO -DSYSV386 -DSYSV" World'.
+
+ Compiler problems --
+ cc is picky about function prototypes and declarations matching. To avoid
+ these problems I would specify -DNeedFunctionPrototypes=0 everywhere.
+
+ cc has resource limitations. I had to simplify one compilicated
+ expression in ./lib/X/XPutImage.c. It also had a problem with a huge
+ macro in ./server/ddx/at386/vga/vgaGlyph.c. Splitting the #define up
+ fixed that. Identifiers are truncated to 32 characters. This caused
+ problems with the two macros sz_xMbufGetMultiBufferAttributesRequest
+ and sz_xMbufGetMultiBufferAttributesReply defined in
+ ./extensions/include/multibufst.h as well as some interdependent
+ identifiers elsewhere in ./extensions/include/multibuf.h,
+ ./extensions/lib/XMultibuf.c and ./extensions/server/multibuf.c. This
+ also caused the compiler to generate the message
+ UNKNOWN ERROR: Contact Microsoft Technical Support
+
+ In the file ./lib/Xt/Selection.c, cc gave me the error
+ static function 'HandleSelectionReplies' not found
+ This function is first declared static within the scope of another
+ function and then defined, as static, later in the same file. So I
+ rearranged some functions so that it is defined before it is invoked.
+ Then I ran into another problem with another function that was defined
+ as static, but later it generated an external reference, one which
+ could never be resolved. By playing musical functions I was able to
+ find a function ordering that produced a usable object file.
+
+ The GNU assembly routines for I/O ports did not hang well with cc. SCO
+ has built-in functions inp, outp and outpw which I used to simulate
+ inb, outb and outw in place of the GNU inline assembly in
+ ./server/ddx/at386/compiler.h. These functions are declared intrinsic
+ using #pragma so the compiler will generate inline in's and out's,
+ i.e. no function calls.
+
+ cc did find a cosmetic bug in ./server/ddx/mi/mispritest.h
+ 95c95
+ < #define LINE_SORT(x1,y1,x2,y2) \
+ ---
+ > #define LINE_SORT(x1,y2,x2,y2) \
+
+ None of the cc fixes are included in the patches.
+
+ I have not tried rcc on this code and I don't think I will. It does not
+ produce very good code.
+
+ That leaves us with gcc, which is capable of compiling all the
+ sources. Be careful to specify the -fpcc-struct-return switch or
+ else you'll produce incompatible code with SCO's libdbm.a.
+
+ I've seen one instances where the three compilers produce mutually
+ incompatible code.
+
+ ./server/ddx/mfb/mfb.h defines the struct mfbPrivGC which contains 3
+ unsigned char followed by two unsigned bitfields, each one bit,
+ followed by a pointer and other stuff.
+
+ struct bad_news {
+ unsigned char a;
+ unsigned char b;
+ unsigned char c;
+ unsigned x:1;
+ unsigned y:1;
+ char * p;
+ };
+
+ offsets generated cc rcc gcc
+ unsigned char a 0 0 0
+ unsigned char b 1 1 1
+ unsigned char c 2 2 2
+ unsigned x:1 4 3 3
+ unsigned y:1 4 3 3
+ char * p 8 4 4
+
+ Not a good situation when you compile different files with different
+ compilers.
