Subject: Re: [dpdk-dev] [PATCH v4 0/5] Clean up pci uio implementations
Date: Tue, 19 May 2015 14:57:47 +0900 [thread overview]
Message-ID: <555AD0DB.4000904@igel.co.jp> (raw)

Hi Bernard,
I've updated the series, because I've found the issue in BSD code.
Also, I have rebased the series for latest master branch.
Could you please read my below comments?

pci_uio_map_resource() {
....snip....
- for (i = 0; i < map_idx; i++)
- rte_free(maps[i].path);
....snip....
}
I removed above code from BSD, because 'maps[i].path' will not be
allocated in BSD code.

struct mapped_pci_resource {
.....snip.....
char path[PATH_MAX];
.....snip.....
};
I left 'path' member like above. It will be used by BSD code even after
BSD support port hotplug function.

Tetsuya
