[Xen-devel] [PATCH v1] Cleanups + various fixes due to libxl ABI + more logging on errors.

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

Hey!

since RFC [https://lists.gnu.org/archive/html/qemu-devel/2015-06/msg07326.html]
 - Added Acks
 - Followed 'xen: Print and use errno where applicable.' suggestion by Stefano
   and added a wrapper.

As I am in the process of syncing the 'dev.config' and Xen's internal
cache of the PCI config space I noticed that some oddities
in the code and figured that having them in would be easier
for me (so I don't have to handle 20 odd patches).


Stefano, patches 1-3 are unchanged since the RFC posting (well, they have the
Ack tag added). Patch:

 [PATCH v1 4/6] xen: use errno instead of rc for xc_domain_add_to_physmap

uses the new wrapper you suggested.

The last two patches are new and I missed them the first time I posted:
 [PATCH v1 5/6] xen/pt/msi: Add the register value when printing
 [PATCH v1 6/6] xen/pt: Use XEN_PT_LOG properly to guard against

In short, please review #4,#5, and #6.
