[dpdk-dev] [PATCH 0/3] dpdk/xen:support DPDK running on Xen Dom0 of SUSE Linux

[Jijiang Liu <jijiang.liu@intel.com>]

Because SUSE linux kernel doesn't not fully follow Linux kernel in main branch, there are some diffirences between them, and DPDK can't run on Xen Dom0 of SUSE Linux. Recently, some customers want us to support this, so we provide this patch set for it.

Now this patch set V1 is not compatible with Linux kernel in main branch, this purpose of sending the patch set is to help those customers who have an urgent need;we probably cooperate with SUSE to eliminate the gap in the future.   

The patch set was validated with the following SW version:

SUSE 11 SP3 (Linux Kernel: 3.0.76-0.11-xen)

Hypervisor: XEN 4.2

GCC: gcc version 4.3.4 [gcc-4_3-branch revision 152973] (SUSE Linux) 

DPDK: 1.8

In addition, users have to a small change in the source codes in SUSE 11 SP3 Linux kernel for this patch set:
comment the 'CONFIG_XEN' define out in ./include/linux/msi.h, or esle there will be some compilation errors. 

//#ifndef CONFIG_XEN
 
struct msi_msg {
        u32     address_lo;     /* low 32 bits of msi message address */
        u32     address_hi;     /* high 32 bits of msi message address */
        u32     data;           /* 16 bits of msi message data */
};
...

//#else /* CONFIG_XEN */
//struct pci_dev;
//struct msi_desc;
//#endif /* CONFIG_XEN */
