2020-10-12misc: clang-11 and gcc-10 supportDamjan Marion1-1/+1
clang-11 complains: error: field 'buffer_template' with variable sized type 'vlib_buffer_t' not at the end of a struct or class is a GNU extension [-Werror,-Wgnu-variable-sized-type-not-at-end] Type: improvement Change-Id: I2cb6b4fde723a05b42cf33dd8130df074f0362ab Signed-off-by: Damjan Marion <damarion@cisco.com>
2019-02-14Add -fno-common compile optionBenoît Ganne1-1/+1
-fno-common makes sure we do not have multiple declarations of the same global symbol across compilation units. It helps debug nasty linkage bugs by guaranteeing that all reference to a global symbol use the same underlying object. It also helps avoiding benign mistakes such as declaring enum as global objects instead of types in headers (hence the minor fixes scattered across the source).

2018-05-04Harmonize vec/pool_get_aligned object sizes and alignment requestsDave Barach1-0/+2
Object sizes must evenly divide alignment requests, or vice versa. Otherwise, only the first object will be aligned as requested. Three choices: add CLIB_CACHE_LINE_ALIGN_MARK(align_me) at the end of structures, manually pad to an even divisor or multiple of the alignment request, or use plain vectors/pools. static assert for enforcement.

2018-03-22memif: version 2Damjan Marion1-2/+31
In version 1 of the protocol sender was always ring producer and receiver was consumer. In version 2 slave is always producer, and in case of master-to-slave rings, slave is responsible for populating ring with empty buffers. As this is major change, we need to bump version number. In addition, descriptor size is reduced to 16 bytes. This change allows zero-copy-slave operation (to be privided in the separate patch).

2018-01-29memif: Add new API calls to manage memif socket names.Jon Loeliger1-2/+5
New API calls and corresponding CLI commands allow the user to manage the socket filenames for memif connections using: vppctl# create memif id <u32> filename <socket-filename> vppctl# delete memif id <u32> and then referencing it later in a memif interface: vppctl# create memif <u32> socket-id <id> mode <mode> <master|slave> ... Corresponding VAT cli entries have also been added. The default memif socket file at id 0 are still always present. The existing memif create/delete CLI commands have been slightly altered into the new syntax: vppctl# create interface memif ... vppctl# delete interface memif ...
