eal: fix vdev allocation on non-0 numa socket

vdev ethdev can not be allocated on a numa socket that is not socket 0.
The reason comes from rte_eth_dev_allocate() which uses rte_socket_id() to
identify the socket on which vdev driver data should be allocated.
However, at this initialization step, rte_socket_id() always returns 0.

Looking at rte_socket_id(), it needs rte_lcore_id() which uses the per-core
global _lcore_id variable. This variable is initialised by
eal_thread_init_master.

"timer: get TSC frequency from /proc/cpuinfo"

The use of cpuinfo to determine the frequency of the TSC is not
advisable and leads to incorrect results when power management is
in use. This is because, while the TSC frequency does not change
in modern cpus with constant_tsc support, the frequency of the core,
and hence the frequency of the core reported by cpuinfo *does* change.

Depending on the current frequency of core 0 when an application is
started, the EAL can get a wildly incorrect value for the TSC freq.
Since frequency is scaled down for power saving, any incorrect value
is likely to be lower than the default, which means that any delay
loops inside the code which rely on the TSC will be shorter than
planned. This can cause issues (reported on the mailing list by a number
of people) where ports are not initialized correctly due to delays being
too short.

10 years agomem: fix mempool for --no-huge

mem: fix mempool for --no-huge

In --no-huge mode, mempool provides objects with their associated
header/trailer fitting in a standard page (usually 4KB).
This means all non-UIO driver should work correctly in this mode,
since UIO drivers allocate ring sizes that cannot fit in a page.

Extend rte_mempool_virt2phy to obtain the correct physical address when
elements of the pool are not on the same physically contiguous memory region.

Reason for this patch is to be able to run on a kernel < 2.6.37 without
the need to patch it, since all kernel below are either bugged or don't
have huge page support at all (< 2.6.28).
