Hi,
I remember that there has been an issue, only seen on Cortex-A7/A15, like the
Allwinner A20.
The fix for that issue is somewhere here[0].
Try this[1] kernel and have a look if it has the same issue or not.
I do not have an A20, so I can’t test it, sorry. But I’ll probably buy

Hi,
iked_cp_fixaddr() is called to replace unspecified (e.g. 0.0.0.0)
addresses by specified (e.g. 192.0.2.1) ones. The function should
return if the address is already set. The check is wrong for the
IPv6 case, as it returns if it's not set. This causes the address
to never be fixed.
ok?
Hi,
Currently there is only one address pool which is either v4 or v6.
This means that we cannot have dual-stack VPNs via iked. Clients
then might tunnel all IPv4 traffic, but IPv6 traffic is still using
the non-encrypted default route, which might be a security issue.

one of the reasons Allwinner A20/sun7i-based boards, like the

Hi,
as the new translation function makes use of errnos as return value,
it probably makes sense to change the "get memory" function, too.
Also I think we should check that mem is not NULL in this function,
as it's exposed in the API. If node or mem is NULL, just return
EINVAL.
ok?

Hi,
this diff makes armv7 map the FDT, if available, and uses it to read
information about the machine's available memory and bootargs.
I'd like to get some opinions about the way I have implemented some
stuff. For instance, I need the size of the FDT so I can properly
copy it. Does it make

Hi,
if you attach sdhc, you automatically compile the pci attachment driver,
even if there's no "sdhc* at pci?" in the config. This might fail on
architectures that don't have pci compiled in.
If I'm not completely mistaken, this can be averted by making the file
depend on sdhc_pci. Tested to

Hi,
I think if we call fdt_parent_node() and give it the root node, it
should return NULL, as there can't be a parent above it. It should
not start searching for the node somewhere in the tree.

Hi,
to allow FDT to be used on ARM I think we should move the FDT code from
socppc to sys/dev/fdt/. Opinions?
Could someone test this diff for me?

Hi,
apparently AArch32 of ARMv8 is backwards compatible to ARMv7,
so we can basically run OpenBSD/armv7 on those new fancy chips.
Early on set_cpufuncs() is called and makes the kernel panic if
it can't find a setup routine for the processor it is running
on. This diff allows set_cpufuncs() to

Hi,
currently we have a rather big list of bits that we remove and set in
the System Control Register. Those differ per processor, so not every
armv7/armv8 processor has the same bits, although they tend to be
rather similar.
I think we should only reset and set a few specific ones that we

Hi,
the Procedure Call Standard used in EABI requires the stack pointer to
be 8-byte aligned by
* exception handlers, before calling AAPCS-conforming code.
* the OS, before giving control to an application.
This diff makes sure our kernel interfaces adhere to that requirement.
Can someone

Hi,
I had the pleasure of debugging a USB mass storage device that showed
interesting behaviour when used with our stack and in combination with
the blink(1) usb device.
The blink(1)-tool depends on libusb. Libusb calls ioctl(USB_DEVICEINFO)
plenty of times to get a map of the USB tree. Per
Hi,
based on the other changes this diff is a draft to make ampintc, the
generic interrupt controller code, FDT aware.
It basically only needs to see if the compatible string matches and
then read out two rows of regs/addresses.
Still, it needs to take care of the address- and size-cell sizes,
Hi,
the armv7_match() function is unused as every platform implements its
own (e.g. imx_match(), exynos_match()).
Ok to remove?

Hi,
currently the armv7 platform busses always match if the board id is set
to something they know. This means that even with a device tree the
platforms will always try to match, even though they should not.
By properly checking for the ma_name member, we can find out if we're
being asked to
