This patch doesn't represent a strict lower bound for GCC and

the Xen RISC-V container and are anticipated to undergo continuous

Initially the patch was introduced by Bobby, who takes the header from

This patch series performs all of the additions necessary to drop the

The patch introduces the following generic functions:

Also, the patch introduces the following generics which are

Currently, RISC-V requires two extensions: _zbb and _zihintpause.
This patch introduces a compiler check to check if these extensions

Additionally, it introduces the riscv/booting.txt file, which contains
information about the extensions that should be supported by the platform.

The patch defines __ffs() in terms of Xen bitops and it is safe
to define in this way ( as __ffs() - 1 ) as considering that __ffs()
was defined as __builtin_ctzl(x), which has undefined behavior when x=0,
so it is assumed that s
This patch introduces the anchor riscv-fixed-randconfig,
which includes all configurations that should be disabled for
randconfig builds.

Recently there are needs to find unallocated/used memory regions
for different use cases at boot time, and the logic of finding
extended regions can be reused for some of the new use cases.
This commit therefore generalize the extended region finding logic.
Firstly, extract the extended region fin
An error message can seen from the init-dom0less application on
direct-mapped 1:1 domains:
```
Allocating magic pages
memory.c:238:d0v0 mfn 0x39000 doesn't belong to d1
Error on alloc magic pages
```
This is because populate_physmap() automatically assumes gfn == mfn
for direct mapped domains. Thi
Currently the GUEST_MAGIC_BASE in the init-dom0less application is
hardcoded, which will lead to failures for 1:1 direct-mapped Dom0less
DomUs.
Instead of hardcoding the guest magic pages region, use the
XEN_DOMCTL_get_mem_map domctl to get the start address of the guest
magic pages region. Add th
For 1:1 direct-mapped dom0less DomUs, the magic pages should not clash
with any RAM region. To find a proper region for guest magic pages,
we can reuse the logic of finding domain extended regions.
If the extended region is enabled, since the extended region banks are
at least 64MB, carve out the
There are some use cases where the toolstack needs to know the guest
memory map. For example, the toolstack helper application
"init-dom0less" needs to know the guest magic page regions for 1:1
direct-mapped dom0less DomUs to allocate magic pages.
To address such needs, add XEN_DOMCTL_get_mem_map
