We will make the functions reserve_crashkernel() as generic, the
xen_pv_domain() check in reserve_crashkernel() is relevant only to
x86, the same as insert_resource() in reserve_crashkernel[_low]().
So move xen_pv_domain() check and insert_resource() to setup_arch()
to keep them in x86.
Suggested-
When reserving crashkernel in high memory, some low memory is reserved
for crash dump kernel devices and never mapped by the first kernel.
This memory range is advertised to crash dump kernel via DT property
under /chosen,
linux,usable-memory-range =
We reused the DT property linux,usable
Introduce macro CRASH_ALIGN for alignment, macro CRASH_ADDR_LOW_MAX
for upper bound of low crash memory, macro CRASH_ADDR_HIGH_MAX for
upper bound of high crash memory, use macroes instead.
Besides, keep consistent with x86, use CRASH_ALIGN as the lower bound
of crash kernel reservation.
Signed-o
There are following issues in arm64 kdump:
1. We use crashkernel=X to reserve crashkernel below 4G, which
will fail when there is no enough low memory.
2. If reserving crashkernel above 4G, in this case, crash dump
kernel will boot failure because there is no low memory available
for allocation.
T
Move CRASH_ALIGN to header asm/kexec.h for later use. Besides, the
alignment of crash kernel regions in x86 is 16M(CRASH_ALIGN), but
function reserve_crashkernel() also used 1M alignment. So just
replace hard-coded alignment 1M with macro CRASH_ALIGN.

For arm64, the behavior of crashkernel=X has been changed, which
tries low allocation in DMA zone and fall back to high allocation
if it fails.
We can also use "crashkernel=X,high" to select a high region above
DMA zone, which also tries to allocate at least 256M low memory in
DMA zone automatical
The lower bounds of crash kernel reservation and crash kernel low
reservation are different, use the consistent value CRASH_ALIGN.

Hi Cristian,
sorry for my late reply.
Thanks for looking into this.
I am preparing a v7 with suggestions proposed by Viresh which, hopefully, should

I had left behind some dealloc, so thanks for spotting!
Many thanks,
Nicola

enabling channel multiplexing and dispatching. This allows for remote host
communication channels across pcie links.
