Unfortunately, I don't know how to go about it, but I'm hopeful to be able to
figure it out with some basic instructions. I'm currently running a fresh RC1
install, and I'm able to boot the system if I set the BIOS to IDE mode, rather
than AHCI.

I just committed them to HEAD (226748 along with a cleanup in 226746). They
should backport to 9.

I'd like to test these patches on my Supermicro machine as well. Unfortunately,
I don't know how to go about it, but I'm hopeful to be able to figure it out
with some basic instructions. I'm currently running a fresh RC1 install, and
I'm able to boot the system if I set the BIOS to IDE mode, rather than AHCI.
Any help would be much appreciated,

GCC chokes here in drv.c:{49,50}: "cannot convert to a pointer type":
v86.ds = VTOPSEG(params);
v86.esi = VTOPOFF(params);
Changed this to ¶ms. Also changed sector_size to uint16_t as noted
by Andriy. Boots perfectly! (Tested with gcc and clang)
Thanks!

Yeah, probably so. We will probably never even use them anyway (just as we
don't
use edd_packet_v3 even though we could probably make use of it to avoid some
bounce buffering in the loader).

I doubt we will ever use them.

I found a document that suggests a possibility of BIOS writing more bytes
to the
array than its current size of 0x42:
http://www.t13.org/documents/UploadedDocuments/docs2008/e08134r1-BIOS_Enhanced_Disk_Drive_Services_4.0.pdf
Of course, the size of the array is passed to BIOS at the start of the
array and
so a _non-buggy_ BIOS should not write beyond the array, but we live in a
non-perfect world.

sector_size should be uint16_t, I think. Ditto for edd_params_v3 and
edd_params_v4.
sizeof(struct edd_params) should be 30, judging from the specs.
> + uint16_tedd_params_seg;

Perhaps the structures should be declared __packed (if only just in case)?
Also, perhaps edd_params_v3 and edd_params_v4 should inherit edd_params in some
"smarter" way to avoid verbatim duplicates.
Other than these issues the patch looks great!
Perhaps later we could do detailed definitions for things like interface paths
for
various cases, etc.

Ugh, it looks like in EDD 4.0 they silently expanded the path field to 16 bytes
instead of 8 as in EDD 3.0 which is why the HP BIOS is probably writing an extra
four bytes.
Ah, so the deal is that the device path bit is variable length and the caller is
supposed to set the length on input which we aren't doing. However, we don't
care about the device path stuff anyway, so we can set a smaller input value.
Perhaps try http://www.freebsd.org/~jhb/patches/edd_params.patch

Hmm, I think we've had to do a similar workaround in the past for a different
BIOS call (SMAP maybe?). However, I do have one request, can we declare an
actual structure instead of a silly char array? Then we can remove the weird
casts with offsets into it, etc. Having an actual struct would be far more
readable and less bug-prone.

Thank you for your very valuable analysis!
I looked at a difference in assembly code of the drvsize function produced by
gcc -Os and by gcc -O1. One thing that was immediately obvious is that gcc
places the params array and the sectors variable in a different order for
different options. One idea is that if BIOS actually writes beyond the end of
the array, then in one case it could be harmless (overwrites the sector
variable), but in the other case it could be more harmful.
I found a document that suggests a possibility of BIOS writing more bytes to the
array than its current size of 0x42:
http://www.t13.org/documents/UploadedDocuments/docs2008/e08134r1-BIOS_Enhanced_Disk_Drive_Services_4.0.pdf
Of course, the size of the array is passed to BIOS at the start of the array and
so a _non-buggy_ BIOS should not write beyond the array, but we live in a
non-perfect world.
Could you please test this hypothesis by trying the following patch?

the debug output may have changed where the problem occurs, I don't
know about that.
With 9.0R drawing near, CFLAGS should be s/-O1/-Os/, until we can figure
out what happens. But as for why gcc's magic -Os is required and clang's
output doesn't work at all, I'm clueless.

Do you have a hypothesis why not using -mrtd could cause a problem (a miscompilation?) ?

I'm seeing the same behavior on a Supermicro X8DT3 BIOS. The latest BIOS update changed the behavior from hanging forever to hanging for 2 seconds before rebooting. The problem occurs with BETA3 and RC1, but not with BETA2. Changing SATA mode from AHCI to IDE in the BIOS gets the OS to boot just fine.

Install runs fine, but when it's time for the first boot, the bootcode emits a single '-' (where usually it would be "spinning" for a moment while loading), hangs for about two seconds, and then reboots. I've used the BETA3 bsdinstall on other (amd64) hardware with GPT and it worked fine. Also, manually adding the GPT label, partitions and bootcode using gpart, then rebooting, shows the exact same behaviour (this was done using the BETA3 "Live CD"). I suspect it's something in the vicinity of "pmbr bootcode vs. newer HP BIOS". (BTW, not related to this issue: hw.memtest.tests=0 should be default. The kernel on a system with 128 GB of RAM needs about two minutes (!) before emitting a single line of output. At first we didn't know about this test and thought there was a serious problem.) - D. ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
Fresh installed Freebsd 9 don't boot from hd
I used FreeBSD 9 amd64 on my HP Proliant DL360 G5 (smart array p400i mirror) as test. It was installed long time ago and often I did csup/rebuild. Yesterday I updated it to 9.0-RC1 and everything was fine. Today I downloaded BETA3 iso and tried to install it. bsdinstall is good. CD ISO boots and installs good. It was fresh install and I choose guided partitioning (GPT) But after reboot my server don't boot from hd. I see HP splash screen, checks for iLo, smart array and when I should see message like "Attempting boot from harddrive" and then "BTX" it reboots. If I use MBR (new install) - system boots from hd normally. I tied 10.0-HEAD-20111018-JPSNAP snapshot from http://pub.allbsd.org/FreeBSD-snapshots/ I tried 9.0-RC1 iso that sometimes appears in ftp.freebsd.org Same story. Is it bsdinstall bug? P.S. in VirtualBox everything is fine. ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
