Subject: IDE-disk hangs - solution/patches NetBSD/FreeBSD
Summary: fixes for lost interrupts with IDE disks
Keywords: hanging-disk, IDE-disk, lost-interrupt


Due to "popular" demand I'm posting these patches to NetBSD/FreeBSD
instead of mailing them around the world :-)

As many have found out there is a problem when using IDE disks on
FreeBSD. Following is a patch that fixes the problem with lost intterrupts.
Both fixes is based on a patch posted here some month ago by
Stefan Behrens?? (sorry I've lost the original article). But anyway it
works (for me :-).
Basically it does a timeout on lost interrupts, starting the operation
again and logging and error message on the console.

It additionally makes the allready present while loop timeouts
independent of CPU speed, and adds minor numbers for easy access to
dos partitions.

workaround for this: if netmask == 0, set it to 0x8000,

Change movl %es: -2(reg) to use a subl $2,reg when fixing up the IDT
entries for bdb.  This seems to be the best way to go.

0967373e1c First steps in rewriting locore.s, and making info useful
when the machine panics.

i386/i386/locore.s:
1) got rid of most .set directives that were being used like
	#define's, and replaced them with appropriate #define's in
	the appropriate header files (accessed via genassym).
2) added comments to header inclusions and global definitions,
	and global variables
3) replaced some hardcoded constants with cpp defines (such as
	PDESIZE and others)
4) aligned all comments to the same column to make them easier to
	read
5) moved macro definitions for ENTRY, ALIGN, NOP, etc. to
	/sys/i386/include/asmacros.h
6) added #ifdef BDE_DEBUGGER around all of Bruce's debugger code
7) added new global '_KERNend' to store last location+1 of kernel
8) cleaned up zeroing of bss so that only bss is zeroed
9) fix zeroing of page tables so that it really does zero them all
	- not just if they follow the bss.
10) rewrote page table initialization code so that 1) works correctly
	and 2) write protects the kernel text by default
11) properly initialize the kernel page directory, upages, p0stack PT,
	and page tables. The previous scheme was more than a bit
	screwy.
12) change allocation of virtual area of IO hole so that it is
	fixed at KERNBASE + 0xa0000. The previous scheme put it
	right after the kernel page tables and then later expected
	it to be at KERNBASE +0xa0000
13) change multiple bogus settings of user read/write of various
	areas of kernel VM - including the IO hole; we should never
	be accessing the IO hole in user mode through the kernel
	page tables
14) split kernel support routines such as bcopy, bzero, copyin,
	copyout, etc. into a seperate file 'support.s'
15) split swtch and related routines into a seperate 'swtch.s'
16) split routines related to traps, syscalls, and interrupts
	into a seperate file 'exception.s'
17) remove some unused global variables from locore that got
	inserted by Garrett when he pulled them out of some .h
	files.

i386/isa/icu.s:
1) clean up global variable declarations
2) move in declaration of astpending and netisr

i386/i386/pmap.c:
1) fix calculation of virtual_avail. It previously was calculated
	to be right in the middle of the kernel page tables - not
	a good place to start allocating kernel VM.
2) properly allocate kernel page dir/tables etc out of kernel map
	- previously only took out 2 pages.

i386/i386/machdep.c:
1) modify boot() to print a warning that the system will reboot in
	PANIC_REBOOT_WAIT_TIME amount of seconds, and let the user
	abort with a key on the console. The machine will wait for
	ever if a key is typed before the reboot. The default is
	15 seconds, but can be set to 0 to mean don't wait at all,
	-1 to mean wait forever, or any positive value to wait for
	that many seconds.
2) print "Rebooting..." just before doing it.

kern/subr_prf.c:
1) remove PANICWAIT as it is deprecated by the change to machdep.c

i386/i386/trap.c:
1) add table of trap type strings and use it to print a real trap/
	panic message rather than just a number. Lot's of work to
	be done here, but this is the first step. Symbolic traceback
	is in the TODO.

i386/i386/Makefile.i386:
1) add support in to build support.s, exception.s and swtch.s

...and various changes to various header files to make all of the
	above happen.

024253188b Try to be a little smarter about touching the date on assym.s, so that
if something changes which doesn't affect it, locore doesn't have to get
rebuilt.  This is at the cost of a genassym and a cmp in every compile,
until someone can figure out how to make `make' smarter itself.

d73546248a Modified the "rude stack hack" that it only applies to addresses within
the stack area and not memory above VM_MAXUSER_ADDRESS.
That way, copyout and friends now work for pages whose page table entries
have not yet been allocated/been paged out.

ce0dbe6e66 Fix for 1542C support, it turns out that the 0x8 extended bios flag is only
set when extended translation is turned on, thus we need to do the mailbox
unlock command no matter what value is in the extended bios flag byte as
the other extensions (ie, > 2 drive support) cause the same problems.

The code has been changed to ALWAYS unlock the mailbox interface on ALL
1542C class boards.

b0da334790 Reverted back to older version of ./genassym, instead of ./genassym.o

this version is better than the original and the lastest version.

eb77639e83 This is my patched version of a busmouse driver originally by Rick Macklem
(rick@snowhite.cis.uoguelph.ca).  I am currently using it with a Microsoft
InPort busmouse, under FreeBSD Epsilon.  I hadn't planned on supporting it,
but I have patched it a few times, and I guess this is now the de facto

As the subject line says:
I can;t believe this typo is still here.

Has NOBODY used the isa_dmastart() routine for 16bit DMA?

I know I just hit the dma regs directly for the AHA1542,
and it appears that either everybody else does as well, or
they only use 8bit DMA (e.g. floppy)

Editors Note:
	The definition of DMA2_CHN was incorrectly using IO_DMA1!

960173b9b2 genassym.c:
Remove NKMEMCLUSTERS, it is no longer define or used.

locores.s:
	Fix comment on PTDpde and APTDpde to be pde instead of pte
	Add new equation for calculating location of Sysmap
	Remove Bill's old #ifdef garbage for counting up memory,
	that stuff will never be made to work and was just cluttering
	up the file.

	Add code that places the PTD, page table pages, and kernel
	stack below the 640k ISA hole if there is room for it, otherwise
	put this stuff all at 1MB.  This fixes the 28K bogusity in
	the boot blocks, that can now go away!

	Fix the caclulation of where first is to be dependent on
	NKPDE so that we can skip over the above mentioned areas.
	The 28K thing is now 44K in size due to the increase in
	kernel virtual memory space, but since we no longer have
	to worry about that this is no big deal.

	Use if NNPX > 0 instead of ifdef NPX for floating point code.

machdep.c
	Change the calculation of for the buffer cache to be
	20% of all memory above 2MB and add back the upper limit
	of 2/5's of the VM_KMEM_SIZE so that we do not eat ALL
	of the kernel memory space on large memory machines, note
	that this will not even come into effect unless you have
	more than 32MB.  The current buffer cache limit is 6.7MB
	due to this caclulation.

	It seems that we where erroniously allocating bufpages pages
	for buffer_map.  buffer_map is UNUSED in this implementation
	of the buffer cache, but since the map is referenced in
	several if statements a quick fix was to simply allocate
	1 vm page (but no real memory) to it.

pmap.h
	Remove rcsid, don't want them in the kernel files!

	Removed some cruft inside an #ifdef DEBUGx that caused
	compiler errors if you where compiling this for debug.

	Use the #defines for PD_SHIFT and PG_SHIFT in place of
	constants.

trap.c:
	Remove patch kit header and rcsid, fix $Id$.
	Now include "npx.h" and use NNPX for controlling the
	floating point code.

	Remove a now completly invalid check for a maximum virtual
	address, the virtual address now ends at 0xFFFFFFFF so
	there is no more MAX!!  (Thanks David, I completly missed
	that one!)

vm_machdep.c
	Remove patch kit header and rcsid, fix $Id$.
	Now include "npx.h" and use NNPX for controlling the
	floating point code.

	Replace several 0xFE00000 constants with KERNBASE

d42d25c451 param.h:

Document that KERNBASE should really be KPTDPTDI << PDRSHIFT, for
now leave it as the constant 0xFE000000 until I make a seperate
common header file for this stuff (vmaddresses.h?)

Remove NKMEMCLUSTERS define, it was only being used to define
VM_KMEM_SIZE, so why have all the indirection.  Besides who wants
to work in CLBYTE sizes chuncks.


pmap.h:

Fix $Id$ and some other minor format clean ups.

Remove the XXX comment about NKPDE, since it now has the correct value
of 7.

Remove unused LASTPTDI and move the APTD into the very end of memory to
free up 4MB of kernel virtual address space.
Remove unused RSVDPTDI and free up 12MB of kernel virtual address space.


vmparam.h

Fix $Id$.

Increase SHMMAXPGS to 512 (2MB) now that there is room for it to be
bigger.  The XXX comment stays until the kernel moves down in memory
to free up enough space to use the proper default of 4MB.

VM_KMEM_SIZE is now a direct constant stating the size of the kernel
malloc region.  Increased the value from 3MB to 16MB.

5c644711a9 ALL:
Removed patch kit headers and rcsid strings, add $Id$.

isa.c:

Removed old #ifdef notyet isa_configure code, since it will never be
used, and I have done 90% of what it attempted to.

Add conflict checking code that searchs back through the devtab's looking
for any device that has already been found that may conflict with what
we are about to probe.  Checks are mode for I/O address, memory address,
IRQ, and DRQ.  This should stop the screwing up of any device that has
alread been found by other device probes.
Print out messages when we are not going to probe a device due to
a conflict so the user knows WHY something was not found.  For example:

aha0 not probed due to irq conflict with ahb0 at 11

Now print out a message when a device is not found so the user knows
that it was probed for, but could not be found.  For example:

ed1 not found at 0x320

For devices that have I/O address < 0x100 say that they are on the
motherboard, not on isa!  The 0x100 magic number is per ISA spec.  It
may seem funny that pc0 and sc0 report as being on the motherboard, but
this is due to the fact that the I/O address used is that of the keyboard
controller which IS on the motherboard.  We really need to split the
keyboard probe from the display probe.  It is completly legal to build
a pc with out one or the other, or even with out both!

npx.c:

Return -1 from the probe routine if we are using the Emulator so
that the i/o addresses are not printed, this is the same trick used
for 486's.

Do not print the ``Errors reported via Exception 16'', and
``Errors reported via IRQ 13'' messages any more, since these just lead
to more user confusion that anything.  It still prints the message
``Error reporting broken, using 387 emulator'' so that the person is
aware that there mother board is ill.

of the kernel virtual space.

Eliminate constant PDRPDROFF, now use PDTDTPI to control location of PTD,
PTDmap and PTDpde

Eliminate constant APDRPDROFF, now use APTDPTDI to control location of APTD,
APTDmap and APTDpde.

Still need to fix Sysmap location (it is still a constant).

.globl statements are now consistent with respect to <comma><space>, the
<space> being removed from all .globl statements.

Document the fillkpt macro as to what registers control what.

Fix some comments that went past column 80, and clean/line some others up.

Remove constand for _Crtat, now use KERNBASE+constant, this still needs work.

Replace constants for offsets of sigcode parameters with symbolic names
from assym.s

Mark the sigreturn() call with XXX since we use the hardcoded constant
for the system call number, this is bogus and should be a #define or
something some place!

The kernel before and after this change was verified with cmp, not one
byte changed.  These are all cosmetic clean up changes that makes the
code more correct and easier to move the kernels virtual address space
and size.

Okay, I tracked down the d*mn thing that is causing the memcpy to be
emmitted by gcc2.  In the following patch is a fix to eliminate the
one place that was causing gcc to do the memcpy in function ie_readframe
for the ie_recv_frame_desc rfd = *(ie->rframes[num]) structure copy.

I also fixed the code so that the NS (XNS) support would compile with
out error and removed the cruft #define ns_* stuff from the softc
structures (I did this a while back for all the other either drivers)

Removed the $Log$ and all of the old log stuff, that is all kept in
the cvs tree, no need to duplicate it in the file... I'll copy it
into my commit message so that it is all retained, except the
revision numbers are going to get screwed up.

It now compiles cleanly under my LINT kernel...

 * Deleted attempt to set watchdog timer, since we don't use it.
 *
 * Revision 1.25  93/04/16  22:15:31  wollman
 * Fixed infinite loop in iestart() which would cause the transmitter
 * to constantly step on the Ethernet, sending the same two packets over
 * and over again.  This crashes the router (really!) and makes other
 * network users very angry.
 *
 * Revision 1.24  93/04/14  23:57:47  wollman
 * Increased transmit buffer size from 1504 to 1512, just in case I don't
 * understand how the MTU is used.

 * Revision 1.22  93/04/14  23:02:16  wollman
 * Unknown changes.
 *
 * Revision 1.21  93/04/12  18:29:33  wollman
 * Added multiple transmit commands.  Note that they are always queued in
 * pairs (there are only two to begin with), and the I flag is only set
 * on the second one.  This should decrease interrupt activity somewhat.
 *
 * Revision 1.20  93/04/12  15:36:05  wollman
 * Changed setup of config block to take into account difference between
 * StarLAN (10BASE-T) and Ethernet: StarLAN is Manchester, Ethernet is NRZ.
 *
 * Revision 1.19  93/03/23  18:58:44  wollman
 * Raised count of receive buffers from 32 to 48 and included analysis of
 * memory usage in a comment near that definition.
 *
 * Revision 1.18  93/03/18  03:59:53  wollman
 * Last try to get large TCP windows to work...
 *
 * Revision 1.17  93/03/18  03:54:10  wollman
 * Added RNR processing as a part of receive interrupts.  Hopefully this
 * will make everything Just Work now.
 *
 * Revision 1.16  93/03/18  03:23:24  wollman
 * Still having problems with RNR conditions.  Basic problem: say we
 * set TCP window to 16k, which is a semsible value.  Then smart
 * partners will blast 16k to us, of which we can fit 8k minus a bit
 * into our buffers.  (Need to look at that memory map..)  So, we get
 * an RNR interrupt.  The problem is, what do we need to do in this case?
 * The original code doesn't work, but it doesn't hang the system either.
 *
 * Revision 1.15  93/03/18  02:37:00  wollman
 * Disabled watchdog timer.  This gets called from a timeout somewhere,
 * which is running up at softclock.  This is at a higher priority than
 * we are, so we can get interrupted in the process of receiving something
 * by the timer expiration, which is not a nice thing to have happen.
 * Question: how can we keep this functionality, but do it in sync with
 * our interrupts?  (Ugh!)
 *
 * Revision 1.14  93/03/18  02:35:46  wollman
 * Fixed some more problems with receive code---it works!
 *
 * Revision 1.13  93/03/17  20:15:59  wollman
 * Think we fixed the serious (showstopper) bugs in 1.12.
 *
 * Revision 1.12  93/03/15  17:45:39  wollman
 * Changed filtering logic dramatically to avoid the unnecessary copyin
 * for BPF or multicast routing when the packet is not for us.  (We
 * have to run in promiscuous mode in this case.)  We still need to
 * deal with the problem of allocating one mbuf per receive buffer;
 * we should be able to get away with a single mbuf for all reasonable
 * incoming packets, and using an mbuf cluster will help avoid unnecessary
 * copying of data.
 *
 * Revision 1.11  93/01/30  20:23:15  wollman
 * Fiddled with reset code to hopefully make it work better when the
 * watchdog timer expires.  Question: why does it make a difference that
 * we do the same thing through ieioctl() as we were doing before.  The
 * old code, when iereset() was called, the receive unit would completely
 * die.  But, a cycle of ifconfig ie0 down ; ifconfig ie0 up' would bring
 * things back to normal.  So, we try to mimic that now.  Grrr...
 *
 * Revision 1.10  93/01/29  17:26:50  wollman
 * Finally fixed multicast routing/BPF mb_map full problem!!!!
 * It turned out that, when we received a packet not for us, we
 * would just return from ie_readframe(), *WITHOUT* freeing the
 * mbuf that the packet was in.  So, when running in promiscuous
 * mode (i.e., multicast routing or BPF without -p), we would have
 * (on our extremely busy subnet 4) a memory leak of epic proportions.
 *
 * We now hold on to a single mbuf chain allocated in this way,
 * and the next time a packet is read, we free it.  Also, the
 * next time a packet is transmitted, we free it.  This way,
 * we never lose more than 6 mbufs total (and on average more like
 * 3).

Subject: Re: Error reading from DAT (fwd)
Date: Mon, 11 Oct 1993 03:02:39 -40962758 (WST)

Some tapes won't do anything until you tell them to load.
Other tapes think that being asked to load is a great excuse to
make the next command return a "unit attention" (media changed) error.
Since we need to do the load, throw in a dummy instruction to cop the
error.

specifically for DEC DAT drives.

64e154d67b Fixed the options hd(1,... to be more accurate (removed word options it
now reads:

printf("use hd(1,a)/386bsd to boot sd0 when wd0 is also installed\n");

I know the person wanted more explination, but there is little room in
the boot blocks for verbose text!

1c622fc1dc SYSPDROFF and SYSPDREND are now calculated using KERNBASE, KERNSIZE and
PDRSHIFT.

The SYSTEM constant that was defined in this file has been replaced
with KERNBASE from param.h.

Changed almost all # style comments to /* */ C style comments.  Several
comments cleaned up so that they make a little more since.

In the comments that describe C calling conventions to assembler routines
used a comma space sequence to seperate arguments and removed the space
between the function name and the argument list.

Removed useless comments like /* clr eax */.

Changed all comma space sequences on assemble instructions to just be comma.

Removed spaces after $ operators to make the file consistent, this may need
to change again (ie: $KERNBASE should probably be $(KERNBASE), but for now
it all seems to work just fine.)  This may become a problem with the C
pre-processor.

Changed several double blank lines to single blank lines that where used
to seperate the I/O routines, these routines are blocked enough that we
don't need double blank lines between them.

Changed sequence of I/O routines to be all input functions, all output
functions instead of just the opposite.

Moved the SHOW_A_LOT debug stuff to near the end of the file.

Changed two occurances of the constant 0xfff to NBPG-1.

845dee6b85 Added a compile time #error so that if the user does not specify on of
the proper I_X86CPU in the config file the following error will occur
while building the kernel: (had to line wrap the error for this message)

../../i386/i386/machdep.c:343: #error This kernel is not configured for one \
of the supported CPUs

156812b7e4 Added PDRSHIFT and KERNSIZE so that the PDR offsets can be calculated in
locore.s instead of being constants (3F8, 3FA).

11851b0ee1 Removed FAT_CURSOR as default since it breaks certain CGA displays
and it is better to conform to the lowest common denominator.
Those wishing to retain it can always use options FAT_CURSOR in
their config files.

09f07fb057 All:
Remove patch kit headers, and add $Id$
	This is mostly to align some more code with NetBSD.

cpu.h:
	Remove the old function vs. include configuration stuff that was
	ifdefed out when we went to inline functions.
	Remove the define of resettodr that made it a nop, there is
	already a function that makes it a nop, no need to #define one.
	Remove the #defines of processor types, they are now defined
	in cputypes.h, #include that file.
	Add struct cpu_nameclass for support of cpu types.

frame.h:
	include sys/signal.h, it will be needed in the future.
	put the sigframe structure here that was in machdep.c

pcb.h:
	Add multiple inclusion protection.
	Add pcb_ldt and pcb_ldt_len to pcb structure, this is for the
	user mode ldt.

3409a2f663 All:
removed patch kit headers and sccsids, add $Id$.  This is a general
	clean up and reallignment with NetBSD-current where possible.

genassym.c:
	removed extranious include of reg.h
	removed old FP_* defines that have been ifdefed out since the patch kit
	removed PCB_SIGC that is not referenced anywhere
	add trapframe and sigframe defines
	add KERNBASE define for use in locore.s

locore.s:
	include npx.h and use NNPX for turning on and off FPU
	include machine/cputypes.h for the types of cpu (used in cpu_identify)
	change SYSPDREND to be one higher, this is really the base of the
	next area, and will be changing again next time I revise the file
	Reverse the NOP defines, you now get slow NOP's by default, this
	may be what is casuing us trouble with some systems.  If you want
	the NOPS to be null you now need to have options DUMMY_NOPS.
	Now get esym from the boot blocks which don't pass it yet, and
	it is not used, but this will be changing.
	Move the bit_colors stuff to be in with the rest of Bruces SHOW_A_LOT
	things for debugging.
	Added NetBSD's CPU type probe code, we now know what type of CPU
	we are running on.
	Adjust kernel pde calcuation to correct for change in SYSPDREND, no
	longer need the +1.

machdep.c
	include npx.h and use NNPX for turning on and off FPU
	include isa.h, map.h(new file), exec.h in preperation for
	changes that are still in process.
	Add some of the code for MACHINE_NONCONTIG that will alow us
	to better map around the BIOS memory area.
	Now print the version, cpu id, real memory and availiable memory
	during boot.
	Correct the calculation of bufpages, the code was mixing pages
	and bytes, it now does the right things.  Removed Bill's hack
	for limiting the erronous calculation.
	add the identifycpu print out code from NetBSD.
	remove the definition of the sigframe struct, it belongs in
	frame.h
	put in printf's about syncing disks on a halt/reboot.
	Change the halted message to be a little easier reading.
	Clean up of the dump messages, makes the source and the output
	much more readable.
	Change 0,0 in several places to have spaces after the commas.

bb9b7f49b4 Remove the ``loader overlaps bss, kernel must bzero'' printf since that
is so often reported as an error condition when it is not.  We print the
size of things so for those who want to know if this happened they can
figure it out from the size information that is printed.

f87a326945 >From NetBSD
Change the cpu "i386" line to 2 lines:
cpu "I386_CPU"
cpu "I486_CPU"
This is so we can do real CPU classification of code.

Fix missing depend for assym.s which does depend on genassym.c
