/dev/bio support?

Is /dev/bio currently supported on ARM, and if not is it planned to be?

For more context, I recently tried to set up full disk encryption on a
Beaglebone Black, and bioctl exited with the error that /dev/bio
couldn't be opened. Is this expected behaviour, and is there any
known workaround?

upgrading packages

There are no precompiled packages for ARM, right?
(The fruits of my BBB's labor are at
http://stare.cz/pub/OpenBSD/packages/arm/ )

So there is no point in pkg_add -u
- what is the preferred way to upgrade packages
after upgrading a snapshot?

I would say recompile everything, hence
# /usr/ports/infrastructure/bin/dpb -c `pkg_info -Paq`
Is this the right thing?

Sadly, dpb(1) fails for me at this BBB
(while it works everywhere else):

   Can't call method "enforce_local" on an undefined value at
/usr/ports/infrastructure/lib/DPB/Config.pm line 186.
   DPB::Config::parse_command_line(DPB::Config, DPB::State=HASH(0x493a77e0)) called at
/usr/ports/infrastructure/lib/DPB/State.pm line 182
   DPB::State::handle_options(DPB::State=HASH(0x493a77e0)) called at
/usr/ports/infrastructure/bin/dpb line 75

This happens with any pkgpath.
Am I missing something obvious?

Question about armv7_icache_sync_range function


I have a question for armv7_icache_sync_range function in

        ldr     ip, .Larmv7_line_size
        cmp     r1, #0x8000
        movcs   r1, #0x8000

The register r1 is the size of range to sync.
My question is, why it is limited to 0x8000 (32K bytes) ?

Similar limitation also existed in following functions:

It's so strange!

The function armv5_ec_icache_sync_range in

        ldr     ip, .Larmv5_ec_line_size
        cmp     r1, #0x4000
        bcs     .Larmv5_ec_icache_sync_all

It will use icache_sync_all function if size greater than 0x4000,

OpenBSD on Olinuxino-Lime2

Hi everybody!

I recently bought a Olinuxino-Lime2 and wanted to see if I could get
OpenBSD up and running.
> https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXIno-LIME2/

It is my first time I am doing something like this and currently I am
stuck.  I tried to boot with the cubieboard image, as this board is
based on an Allwinner A20 and this thread said that it might be
supported (I do not need X):
> https://marc.info/?l=openbsd-arm&m=139894585630709&w=2

The original u-boot loader used by the miniroot failed to initialize
the DRAM (both 5.7-release and 5.8-release), so I used the one from
over here:

Now I have the same problems as Leonardo describes another thread.
The system boots and freezes at some point. I have attached a full log
> https://marc.info/?l=openbsd-arm&m=144386766902942&w=2

I have read all the threads which showed up for the search terms
'olinuxino' and 'sunxi', but none gave me any helpful advise.

Does anyone have some idea I could try?

Thank you.

pcDuino3_Nano mount root problems on boot

  I'm back trying to make the pcDuino3_Nano board
work with OpenBSD.

The u-boot version shipped with the board:
U-Boot 2011.09-rc1 (Jul 03 2013 - 17:40:47) Allwinner Technology

Is not able to load openbsd from sd card.

Back in august I wrote to the list with a config option for
u-boot 2015-07 to make the bsd.umg image load; that
[*] Enable workarounds for booting old kernels 
under ARM Architecture of the uboot menuconfig.

Now, using the last uboot git version

U-Boot 2015.10-rc3-00297-g1a9c229 (Sep 27 2015 - 11:01:54 +0200) Allwinner Technology

it would stop at dram initialization:

DRAM:Timeout initialising DRAM

I had to change another config option to make it work:

"ARM Architecture" -> "sunxi dram timings" set to "JEDEC DDR3-800E / DDR3-1066G / DDR3-1333J"

instead of "Magic vendor timings from Android"

Now I'm back to square one with the same problem: openbsd loads fine but stuck at the
