Hi,
I am playing around with openbsd kernel source code on a raspberry pi 4.
I have a couple of questions:
Does openbsd use low or high peripheral mode?
At what virtual address does openbsd map the peripheral base address ?
I had a look at the source code but that part is still a bit cryptic for
dress space ) to a much higher memory location.
Best,
Alessandro

Hi,
I am using openbsd 6.8 on a raspberry pi 4. I have a problem and wonder if
this is an arm
or arm64 specific bug.
In my code I am creating an uvm_object and mapping it in kernel memory
using uvm_map.
uvm_map returns an address which is not aligned with PAGE_SIZE and later
when I call
uvm_unma
Hi all,
in the kernel I see the code below (file: arm64/dev/ampint.c lines:643-666).
void

struct ampintc_softc *sc = ampintc;
struct intrhand *ih;
void *arg;
uint32_t iack_val;
int irq, pri, s, handled;
iack_val = ampintc_iack();
#ifdef DEBUG_INTC
if (iack_val !

Hi all,
I am writing a custom boot loader for openbsd the raspberry 4 and 400.
I have seen on the internet that there used to be a problem with earlier
versions of u-boot leading to a panic due to a call to do_el0_error(), just
after setting the address for bwfm0.
I have the exact same crash o
