When using vfio, the probe fails for BAR > 0 after the commit-id 90a1633b2 (eal/linux: allow to map BARs with MSI-X tables). While debugging further, found that the BAR region offset and size read from vfio are u64, but are assigned to uint32_t variables. This results in the u64 value getting truncated to 0 and passing wrong offset and size to mmap for subsequent BAR regions. The fix is to use unsigned long for the offset and size. This is based on patch by Alejandro Lucero <alejandro.lucero@netronome.com> posted at below: http://dpdk.org/ml/archives/dev/2015-June/020201.html and updated with diff from below to fix 32-bit compilation: http://dpdk.org/ml/archives/dev/2015-July/020963.html Fixes: 90a1633b2347 ("eal/linux: allow to map BARs with MSI-X tables") Signed-off-by: Alejandro Lucero <alejandro.lucero@netronome.com> Signed-off-by: Rahul Lakkireddy <rahul.lakkireddy@chelsio.com> Signed-off-by: Kumar Sanghvi <kumaras@chelsio.com>
