log: do not drop debug logs at compile time

Today, all logs whose level is lower than INFO are dropped at
compile-time. This prevents from enabling debug logs at runtime using
--log-level=8.

The rationale was to remove debug logs from the data path at
compile-time, avoiding a test at run-time.

This patch changes the behavior of RTE_LOG() to avoid the compile-time
optimization, and introduces the RTE_LOG_DP() macro that has the same
behavior than the previous RTE_LOG(), for the rare cases where debug
logs are in the data path.

So it is now possible to enable debug logs at run-time by just
specifying --log-level=8. Some drivers still have special compile-time
options to enable more debug log. Maintainers may consider to

pmdinfogen: fix endianness with cross-compilation

pmdinfogen has a bug in which, during build, it pulls in rte_byteorder.h to
obtain the rte macros for byteswapping between the cpu byte order and big or
little endian.  Unfortunately, pmdinfogen is a tool that is only meant to be run
during the build of dpdk components, and so, it runs on the host.  In cross
compile environments however, the rte_byteorder.h is configured using a target
cpu, who's endianness may differ from that of the host, leading to improper
swapping.

The fix is to use host system defined byte swapping routines rather than the
dpdk provided routines.  Note that we are using non posix compliant routines, as
the posix compliant api only addresses 16 and 32 bit swaps, and we also need 64
bit swaps.  Those macros exist (via endian.h), but BSD and Linux put that header
in different locations so some ifdeffery is required.

7 years agodoc: announce iomem and ioport removal from igb_uio
Jianfeng Tan [Thu, 22 Sep 2016 05:44:05 +0000 (05:44 +0000)]
doc: announce iomem and ioport removal from igb_uio

In igb_uio, iomem is mapped, and both ioport and io mem are recorded
into uio framework (then into sysfs files), which is duplicated with
what Linux has already provided for user space, and makes the code
too complex.

For iomem, DPDK user space code never opens or reads files under
/sys/pci/bus/devices/xxxx:xx:xx.x/uio/uioY/maps/. Instead,
/sys/pci/bus/devices/xxxx:xx:xx.x/resourceY are used to map device
memory.

For ioport, non-x86 platforms cannot read from files under
/sys/pci/bus/devices/xxxx:xx:xx.x/uio/uioY/portio/ directly, because
non-x86 platforms need to map port region for access in user space,
see non-x86 version pci_uio_ioport_map(). x86 platforms can use the
the same way as uio_pci_generic.

This will remove iomem and ioport mapping in igb_uio kernel module,
and adjusts the iomem implementation in both igb_uio and
uio_pci_generic:
  - for x86 platform, get ports info from /proc/ioports;
  - for non-x86 platform, map and get ports info by pci_uio_ioport_map().

Note: this will affect those applications who are using files under
/sys/pci/bus/devices/xxxx:xx:xx.x/uio/uioY/maps/ and
/sys/pci/bus/devices/xxxx:xx:xx.x/uio/uioY/portio/.

net/i40e: fix VF bonded device link down

If VF device is used as slave of a bond device, it will be polled
periodically through alarm. Interrupt is involved here. And then
VF will send I40E_VIRTCHNL_OP_GET_LINK_STAT message to
PF to query the status. The response is handled by interrupt
callback. Interrupt is involved here again. That's why bond
device cannot bring up.

This patch removes I40E_VIRTCHNL_OP_GET_LINK_STAT
message. Link status in VF driver will be updated when PF driver
notify it, and VF stores this link status locally. VF driver just
returns the local status when being required.
