Hi all,
This patch aims is a first attempt to write the hypercall dispatch in assembly
in order to avoid reloading the hypercall arguments from the stack.
I've posted an early version to get comments and only the ARM64 side has been
implemented.
A branch with the code can be found here:
git://x
This has been fully implemented in assembly so it's not necessary to
keep it anymore.

One of the missing pieces is a new boot ABI, that replaces the PV boot

Switches the build system to rely on the options and flags generated by
Kconfig to control what gets built and how. Follow on patches will
convert items to be prefixed with CONFIG_. Additionally remove a #define
that resulted in a redefined variable when building for arm.

current is a define which is replaced by a read to a system register.
Rather than reading the system registers multiple store the result in a
local variable.

Currently when the guest is issuing an hypercall, all the registers are
saved in the stack and then later reload from the stack before calling
the hypercall dispatcher.
To avoid spending time loading from the stack the arguments, the
hypercall handler can be implemented in assembly.

Previously we would retry only the body, but not LOCK TABLEs.
We got away with it before because of the heavyweight locking of even
long-running read-only transactions, but now the LOCK TABLEs can fail
(at least in a mixed-version system, and perhaps even in a system with
only new code).
Addition
Currently the LRs are cleared every time we entered in Xen from a guest
before any action is taken by the hypervisor. This requiring to reload
the guest registers from the stack when an hypercall is handled for
instance.
However, we only need to clear the LRs for the following actions:

Now that Xen hypercall is fully dispatched in assembly, the code to
handle HVC32/HVC64 is mostly the same.
Create an helper to avoid duplicating the code.

Why? A couple of stack operations are in the noise, performance wise.

After starting the xenstore domain write the basic data (domid and

Each hypercalls have different number of arguments. To avoid worry about
the number of arguments, all the hypercall handler are cast to a
5-arguments function. However, based on the C-spec (see 6.3.2.3 paragraph 8
and 6.7.5.3 paraph 2) the behavior is undefined.

The shorthand lr and the macros push/pop are useful for any assembly
code.
