[PATCH 0/9] user-mode: Prune build dependencies (part 3)

[Philippe Mathieu-Daudé]

This is the second part of a series reducing user-mode
dependencies. By stripping out unused code, the build
and testing time is reduced (as is space used by objects).

Part 3:
- Extract code not related to user-mode from hw/core/qdev-properties.c
- Reduce user-mode QAPI generated files

This is doing more that *just* using qemu_strtol, it's also validating the
input.  I don't think you need to adjust the patch, just improve the commit
message.  With that,

Correct. I'll add a comment, as currently we ignore incorrect input due 
to the implicit cast to uint8_t:

struct MACAddr {
     uint8_t a[6];
};

     mac->a[i] = strtol(str+pos, &p, 16);

Thanks!

You can drop the e == p test.  That's done in check_strtox_error, called by
qemu_strtoul.  Same for the other 2 instances.

The range check looks wrong, as we have not yet decided if this element is
"dom" or "bus".

> -    if (dom > 0xffff || bus > 0xff || slot > 0x1f || func > 7) {
> +    if (bus > 0xff) {

I think it makes sense to leave this line unchanged.  Increase the slot and
func local variables increased to unsigned long so that the range check isn't
truncated.

[PATCH 6/9] hw/core/qdev-properties: Export some integer-related functions

[Philippe Mathieu-Daudé]

We are going to split this file and reuse these static functions.
Declare them in the local "qdev-prop-internal.h" header.

[PATCH 8/9] hw/core: Add qdev stub for user-mode

[Philippe Mathieu-Daudé]

While user-mode does not use peripherals (devices), it uses a
CPU which is a device.
In the next commit we will reduce the QAPI generated code for
user-mode. Since qdev.c calls qapi_event_send_device_deleted(),
let's add a stub for it.

This should be:

    obj-$(call lnot,$(CONFIG_SOFTMMU)) += qdev-stubs.o

(not common).

Actually I moved it to stub-obj-y which makes things easier.

No, common-obj- is the right thing, followed by

common-obj-$(CONFIG_ALL) += qdev-stubs.o

I don't understand CONFIG_ALL magic, why is that different to common-obj-y?

Anyway your suggestion works, so I'll blindly use it, thanks.

[PATCH 9/9] qapi: Restrict code generated for user-mode

[Philippe Mathieu-Daudé]

A lot of QAPI generated code is never used by user-mode.

Rewrite the QAPI_COMMON_MODULES variable one entry per line,
and split it in 3 groups:
- always used
- use by system-mode or tools
- only used by system-mode
