2013-09-17lib: update version to 1.4.1r1 and add helper macrosv1.4.1r1Thomas Monjalon
Applications can test versions, for compatibility, this way: #if RTE_VERSION >= RTE_VERSION_NUM(1,2,3,4) RTE_VERSION was already defined for use with rte_config. It is moved in rte_version.h and updated to current version number. Note that the first tag having this helper is 1.2.3r2. Releases 1.3.0r0, 1.3.1r0, 1.4.0r0 and 1.4.1r0 have not this patch.

2013-09-17kni: fix build with kernel < 3.3 with netdev_features_t backportAdrien Mazarguil
The netdev_features_t typedef appeared in Linux 3.3, but checking the kernel version isn't enough with some distributions (such as Debian Wheezy) that backported it into 3.2, causing a compilation failure due to redefinition. Since the presence of a typedef can't be tested at compile time, this commit adds type kni_netdev_features_t, which, depending on the kernel version, translates either to u32 or netdev_features_t.

2013-09-17ethdev: fix non-reconfigurable pmd initThomas Monjalon
Some Poll-Mode Drivers (PMD) are not reconfigurable and, thus, do not implement (rx|tx)_queue_release functions. For these drivers, the functions rte_eth_dev_(rx|tx)_queue_config must return an ENOTSUP error only when reconfiguring, but not at initial configuration. Move the FUNC_PTR_OR_ERR_RET check into the case of reconfiguration. Signed-off-by: Thomas Monjalon <thomas.monjalon@6wind.com> Acked-by: Ivan Boule <ivan.boule@6wind.com>

Update em, igb, and ixgbe drivers to return the value of the 4 XOFF/XON counters through the `rte_eth_stats_get` function exported by the DPDK API.

2013-09-17pci: use igb_uio mapping only when neededThomas Monjalon
Since DPDK 1.4, if RTE_EAL_UNBIND_PORTS is disabled, igb_uio mapping is done for all devices (commit eee16c964cd), breaking some non-Intel drivers. But pci_uio_map_resource() should only be called for Intel devices (using igb_uio kernel module). The flag RTE_PCI_DRV_NEED_IGB_UIO is set for all those devices, even when RTE_EAL_UNBIND_PORTS is disabled (fixes commit a22f5ce8fcc).

2013-09-17pci: do not check BAR0 mappingDavid Marchand
Since DPDK 1.4, bars mapping is checked and prevent from initializing drivers which do not use igb_uio mapping (see commit eee16c964cd). There is no need to check for bars mapping, especially BAR0 is not required. If bars mapping failed, then pci_uio_map_resource will fail and we won't reach this check. So get rid of BAR0 check.

2013-09-17mem: fix log for --no-hugeThomas Monjalon

2013-09-17mem: fix mempool for --no-hugeDamien Millescamps
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. This is a first step for enhancement PR #29696. 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).

2013-09-17mem: get memzone from any CPU socket when hugepages are disabledAdrien Mazarguil
When huge pages are disabled, memory is allocated for a single, undefined CPU socket using malloc(), causing rte_memzone_reserve_aligned() to fail most of the time. This patch causes that memory to use SOCKET_ID_ANY instead of 0, and allow it to be used in place of any socket ID specified by user.

2013-09-17mem: fix rte_malloc(SOCKET_ID_ANY), try to allocate on other nodesOlivier Matz
Before this patch, rte_malloc(SOCKET_ID_ANY) was equivalent to rte_malloc(this_socket). If the user specifies SOCKET_ID_ANY, it means that memory can be allocated on any socket. So fix the behavior of rte_malloc() in order to do that. The current CPU socket is still the default, but if it fails, other sockets are tested.

2013-09-17mem: get physical address of any rte_malloc bufferDidier Pallard
Get physical address of any rte_malloc allocated buffer using function rte_malloc_virt2phy(addr). The rte_memzone pointer is now stored in each allocated memory block header to allow simple computation of physical address of a block using the memzone it comes from. The function rte_malloc_virt2phy has a dependency on rte_memory.h: phys_addr_t must be defined.

2013-09-17mem: get physical address of any pointerDamien Millescamps
Extract rte_mem_virt2phy() from find_physaddr(). rte_mem_virt2phy() permits to obtain the physical address of any virtual address mapped to the current process calling this function. Note that this function is very slow and shouldn't be called after initialization to avoid a performance bottleneck. The memory must be locked with mlock(). The function rte_mem_lock_page() is a mlock() helper that lock the whole page. A better name would be rte_mem_virt2phys but rte_mem_virt2phy is more consistent with rte_mempool_virt2phy.

2013-09-17eal: fix recording of detected/enabled logical coresIvan Boule
1) In the EAL initialization phase, invoke the function rte_eal_cpu_init to detect the set of running cores (and enable them by default) before processing the [enabled] core mask option that is performed during the parsing of EAL arguments. 2) In the function rte_eal_cpu_init(): - to parse the set of all running logical cores on the machine, do not use the RTE_LCORE_FOREACH macro that considers the set of already detected cores... Instead, use a standard loop based on the RTE_MAX_LCORE constant. - explicitely set to ROLE_RTE the role of each detected logical core that is recorded in the EAL configuration, as all running cores are enabled by default. 3) In the function eal_parse_coremask(), update the "lcore_count" field of the EAL configuration with the effective number of logical cores that are set in the mask of enabled logical cores.

2013-09-17eal: fix type of pointer arithmetic resultThomas Monjalon
Adding or subtracting a value to a pointer makes a new pointer of unknown type. So typeof() is replaced by (void*) in RTE_PTR_ADD() and RTE_PTR_SUB(). But RTE_PTR_ALIGN_* macros have in their explicit API to return a pointer of the same type. Since RTE_PTR_ALIGN_CEIL is based on RTE_PTR_ADD, a typeof() is added to keep the original behaviour.
