2020-10-06vppinfra: add heap header in front of dlmalloc spaceDamjan Marion1-11/+0
This patch adds smal header in front of dlmalloc space, and it stores some additional information about the heap. Immediate benefit of this patch is that we know the underlying page size si we can display heap page statistics / real memory usage.

2020-09-28vppinfra: don't call dlmalloc API directly from the codeDamjan Marion1-19/+12
- it is confusing from end consumer perspective that some thing is somewhere called heap and somewhere mspace - this is base for additional work where heap pointer is not the same thing like mspace Type: improvement Change-Id: I644d5a0de17690d65d164d8cec3c5654571629ef Signed-off-by: Damjan Marion <damarion@cisco.com>

Callbacks for monitoring and performance measurement: - Add new callback list type, with context - Add callbacks for API, CLI, and barrier sync - Modify node dispatch callback to pass plugin-specific context - Modify perfmon plugin to keep PMC samples local to the plugin - Include process nodes in dispatch callback - Pass dispatch function return value to callback Type: refactor Signed-off-by: Tom Seidenberg <tseidenb@cisco.com> Change-Id: I28b06c58490611e08d76ff5b01b2347ba2109b22
2020-02-11vppinfra: remove the historical mheap memory allocatorDave Barach1-83/+0

2019-07-16api: enable binary API event logging in vatDave Barach1-7/+11
Cleaned up a few instances of side-bet elog_string hash table usage. Elog_string handles that problem itself. Add cli commands to vat to initialize, enable/disable, and save an event log. Event logging at the same time in both vpp and vat yields a pair of event logs which can be merged by the "test_elog" tool.

2019-05-17Add a debug-CLI leak-checkerDave Barach1-0/+25
leak-check { <any-debug-cli-command-and-args> } Hint: "set term history off" or you'll have to sort through a bunch of bogus leaks related to the debug cli history mechanism. Cleaned up a set of reported leaks in the "show interface" command. At some point, we thought about making a per-thread vlib_mains vector, but we never did that. Several interface-related CLI's maintained local static cache vectors. Not a bad idea, but not useful as things shook out. Removed the static vectors.

2019-05-10cli: Add return value in cli_inbandOle Troan1-1/+6
Even when a CLI command called through the cli_inband API failed the API would return 0 (SUCCESS). This patch fixes that, but since most CLI handlers return error->code == 0, in most failure cases it will return -1 (UNSPECIFIED ERROR).

Configure w/ --enable-dlmalloc, see .../build-data/platforms/vpp.mk src/vppinfra/dlmalloc.[ch] are slightly modified versions of the well-known Doug Lea malloc.

2018-06-13cli: 'restart' should close open files (VPP-1068)Chris Luke1-2/+17
- On 'restart' close all registered files (except stdio) so that the new process has a clean start; in particular, CLI sockets, API sockets, tun/af_packet etc descriptors all need to close so they're not left open but unused by the new VPP process. To do this we iterate all the files registered for the polling mechanism and close() them.[1] - While we're here, retain the original environment on 'restart'; several things make use of it. [1] An alternative mechanism would be to mark all files with CLOEXEC on opening; I think that is a little fragile for this fairly esoteric use case.

2018-06-05VPP API: Memory traceOle Troan1-9/+49
if you plan to put a hash into shared memory, the key sum and key equal functions MUST be set to constants such as KEY_FUNC_STRING, KEY_FUNC_MEM, etc. -lvppinfra is PIC, which means that the process which set up the hash won't have the same idea where the key sum and key compare functions live in other processes.

2017-04-06Use thread local storage for thread indexDamjan Marion1-3/+3
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.
