Error correction: this is todays BK, not pristine 2.4.23 (if that
matters).

2.4.23-bk bogus edd changeset - Re: 2.4.23 compile error in edd

[Anton Altaparmakov]

Marcelo,

2.4.23-bk has a changeset (post 2.4.23 release TAG) that makes edd not
compile as Meelis Roos already reported:

Further, looking at the header files the closest constant that does exist
is #define DISK80_SIG_BUFFER 0x228 from include/asm-i386/edd.h.

However, changing DISKSIG_BUFFER to DISK80_SIG_BUFFER causes the kernel to
reboot the computer as soon as it starts booting.  Basically I select it
in grub and the screen changes graphics mode and by the time it has
finished the switch the computer reboots.

2.4.23-bk at the 2.4.23 release TAG works fine and compiles fine with the
same .config.

Best regards,

	Anton

Yeah, that's my bad, setup.c should say DISK80_SIG_BUFFER not
DISKSIG_BUFFER.

With this, it works for me on my PowerEdge 4600 with disks on the
aic7xxx, and the same int13 code works on all other PowerEdge servers
we've ever tried it on.  What kind of system and disks (IDE/SCSI) and
BIOS do you have for those please?

Can you send me your .config and I'll try to reproduce? 

Thanks,
Matt

.config is attached (I called it edd_config).  

With latest 2.4-BK which includes your compile fix, compiling the kernel
with the attached .config, installing and attempting to boot the kernel
causes immediate reboot on my workstation.

Disabling EDD in the .config, recompiling and installing the kernel
makes it boot just fine.

My workstation is a P4 2.6GHz hyperthreading (with SMP in kernel
enabled), 1GB DDR400 RAM, the motherboard is an Intel D865GLC Desktop
Board, latest BIOS version BF86510A.86A.0049.P11 (I just updated the
BIOS to this and tried again just in case that made a difference).

Ok, I'm betting that your BIOS doesn't like the int13 call in setup.S for some
reason.

#if defined(CONFIG_EDD) || defined(CONFIG_EDD_MODULE)
# Read the first sector of device 80h and store the 4-byte signature
        movl    $0xFFFFFFFF, %eax
        movl    %eax, (DISK80_SIG_BUFFER)       # assume failure
        movb    $READ_SECTORS, %ah
        movb    $1, %al                         # read 1 sector
        movb    $0x80, %dl                      # from device 80
        movb    $0, %dh                         # at head 0
        movw    $1, %cx                         # cylinder 0, sector 0
        pushw   %es
        pushw   %ds
        popw    %es
        movw    $EDDBUF, %bx
        int     $0x13
        jc      disk_sig_done
        movl    (EDDBUF+MBR_SIG_OFFSET), %eax
        movl    %eax, (DISK80_SIG_BUFFER)       # store success
disk_sig_done:
        popw    %es


To test this, would you mind #if 0'ing everything starting with
movb $READ_SECTORS, %ah   through the popw %es at the end?  That
should leave you with a file in /proc/bios/int13_dev80/mbr_signature
that says 0xFFFFFFFF, but a booting system.

I'm wondering if %eax shouldn't be zeroed before the int13.  The
bottom word gets set properly, but the top word is 0xFFFF which your
BIOS may not like?  That would be another test, add an

 xor %eax, %eax

before the movb $READ_SECTORS, %ah.


My BIOSs I've seen this on work, so it could be BIOS-dependent;
clearing eax before setting the lower bytes would be OK if that fixes
it.

I'm travelling Monday and Tuesday, but will respond ASAP.

Thanks,
Matt

No, still reboots.

No.  The higher 16 bits are irrelevant.  I played with this today by
inserting debugging into the EDD archi/i386/boot/setup.S code as well as
into the EDD arch/i386/kernel/setup.c code.  I will give you details
below but here is what I believe is the conclusion:

The ds segment is not pointing to the correct segment AND/OR the offsets
into the segment used for the writes are bogus.  You write straight into
ds and ds:si referenced memory but you never setup ds in the first
place.  So the writes done by the EDD code corrupt the loaded compressed
kernel and the decompression fails.

I may be wrong of course.  (-:

Now the experiments I did:

1) 

Disable the entirety of the memory writes done by EDD code in setup.S
with destination ds:si as well as the initial ds:DISK80_SIG_BUFFER.
Basically I just did #if 0 #endif arround the whole EDD code!

To match this, edit setup.c::copy_edd() and add these lines at the end:

	eddnr = 0;
	edd_disk80_sig = -1;

This makes my kernel boot just fine and EDD tells me that no devices are
present.

Thus it is likely that the setup.S EDD code is what kills us.

2)

Leaving the setup as in experiment 1) with only one modification; in
setup.S move the top two EDD lines above the #if 0, i.e.:

	movl    $0xFFFFFFFF, %eax
	movl    %eax, (DISK80_SIG_BUFFER)       # assume failure

Booting this kernel now causes an immediate reboot!

3)

I added a readkey (ah = 0, int 0x16) at the end of the EDD code in
setup.S so that I need to press a key to continue.  This allowed me to
tell when the computer is rebooting.  This also allows the graphics card
to have changed graphics mode and I can see messages on screen before
the reboot happens.

Repeating experiment 2 with my readkey code added, the kernel waits for
my key press (after having done the write to (DISK80_SIG_BUFFER), then
displays "Decompressing kernel..." and then reboots, i.e. it never
completes kernel decompression.

This is what leads me to believe that the kernel image has been
corrupted by the above memory write.

-- end of experiments --

I haven't really spent time thinking about ds and offsets and what they
should be set to but I hope I have given you enough information to fix
this yourself.  (-:

Please also note that you may want to consider adding this around your
first int 0x13 call (the one to read the MBR):

movb	$READ_SECTORS, %ah
[snip]
pushw	%dx		# work around buggy BIOSes
stc			# work around buggy BIOSes
int	$0x13
sti			# work around buggy BIOSes
popw	%dx

This is what Microsoft uses apparently to work around various buggy BIOS
implementations - ref: Ralf Brown's Interrupt list 61, which I consider
the ultimate and definite guide to interrupts. (-:

Further, at the Getdeviceparameters int 0x13 call, you may want to zero
the two bytes following the EDDPARMSIZE in %ds:(%si) before doing the
interrupt as your own company's PhoneixBIOS 4.0 Release 6.0 machines
didn't work unless this was the case (ref: Ralf Brown's Interrupt list
61).

Finally, would it not be prudent to check the result of
checkextensionspresent int 0x13 call before doing the
getdeviceparameters int 0x13 call?  For example this would do just that:

[snip]
movw	%cx, %ds:-2(%si)		# store extensions
[snip]                                                                                        testw	$7, %cx				# Is Function 48 supported?
jz	edd_skip_getdevparms		# If not, skip the call...

movb	$GETDEVICEPARAMETERS, %ah	# Function 48
int	$0x13				# make the call
					# Don't check for fail return
					# it doesn't matter.
edd_skip_getdevparms:

Just a few thoughts.

Best regards,

	Anton

ds is set up already to point at the empty_zero_page, else none of
what I'm doing is correct.  But, it is very likely that something else
is using 0x228 in empty_zero_page but isn't marked as using it in
Documentation/i386/zero-page.txt.

You've been patient, and thorough.  As another test, could you change
include/asm-i386/edd.h: DISK80_SIG_BUFFER from 0x228 to 0x2cc (the
four bytes immediately before the e820 memory buffer), and see if that
helps?  If so, I'll submit a patch to use that instead, and another
that markes 0x228 as in use by something else.

I'm quite certain that ds is correct, but that 0x228 may be in use by
something else.

OK, I'll look into that too.

Ahh, yes.  I read that now.  OK, no harm in doing so, I'll add that.

So, I thought about this for a while when I first wrote the code.  I
haven't run across *any* BIOSses yet which didn't implement function
48 for at least some version of EDD; it may not be version 0x30, but we've got
space reserved for it up to the size 0x30 could return, so it doesn't
matter.  If it returns anything in function 41, then it will return
something in function 48 too.  I could be wrong I suppose, but none of
the BIOS reports I've seen suggest otherwise.

Thanks,
Matt

Hi Matt,

sorry for the delay but I am now on holidays until January because of my
impending wedding and I won't be back at work, where the affected PC lives
until 5th or 6th January (whichever is the Monday).  I will try it then,
sorry to have to keep you waiting so long.

Best regards,

	Anton

Same here - instant reboot when EDD is enabled. Do you need my config
also? The mainboard is Intel D815EEA2 with latest BIOS
(EA81520A.86A.0039.P21.0211061753).

Ok, 2 reports now.  With Anton off getting married, can you assist
with debugging this (I've tried, and can't reproduce it on any systems
available to me) ?

In include/asm-i386/edd.h, change:
#define DISK80_SIG_BUFFER 0x228

to

#define DISK80_SIG_BUFFER 0x2cc

and see if that helps.  What I'm thinking right now is that 0x228 is
being used by a boot loader somehow (what's your boot loader?) though I can't
yet prove it, and it isn't listed in
Documentation/i386/zero-page.txt.  But Anton showed that the int13
calls the EDD code makes (or even if you remove those) succeeds, but
by writing something into 0x228 the kernel uncompress fails.  I'm
hoping that by moving the buffer to 0x2cc (immediately before the e820
memory map reserved space) that it will succeed.

Thanks,
Matt
