It will depends whether your application need to use HUGETLB_ELFMAP and/or HUGETLB_SHM since it is not implemented on glibc.  The HUGETLB_ELFMAP requires a lot of hacks and kernel/toolchain have worked to make THP to work better with text and data segments, and I think it is unlikely that we will support on glibc anytime soon (it will most likely require changes in the ELF gnu extension to explicit use huge pages). For HUGETLB_SHM it should be easy to adapt the code to align to page size and add SHM_HUGETLB. I think it might be doable to add support on glibc with an extra tunable as well to avoid code changes in the application.  I still prefer to adapt the the application itself because libhugetlbfs subtly change shmget semantic under the hood (by changing memory alignment and segment). >> Or just run "GLIBC_TUNABLES=glibc.malloc.hugetlb=2 app"? Based on the command line you pasted, it should be only that.  It will cover all memory allocation done by malloc. > > I am still in checking how to upgrading to glibc 2.35 in system.

[PATCH v3 0/6] uadk - add wd_comp_init2
by Yang Shen 29 Sep '22

29 Sep '22

The current uadk initialization process is: 1.Call wd_request_ctx() to request ctxs from devices. 2.Call wd_sched_rr_alloc() to create a sched(or some other scheduler alloc function if exits). 3.Initialize the sched. 4.Call wd_<alg>_init() with ctx_config and sched. Logic is reasonable. But in practice, the step of `wd_ request_ Ctx() ` and `wd_ sched_ rr_alloc() ` are very tedious. This makes it difficult for users to use the interface. One of the main reasons for this is that uadk has made a lot of configurations in the scheduler in order to provide users with better performance. Based on this consideration, the current uadk requires the user to arrange the division of hardware resources according to the device topology during initialization. Therefore, as a high-level interface, this scheme can provide customized scheme configuration for users with deep needs. All algorithm initialization interfaces have the same input parameters and behavioral logic. The pre-processing of the wd_<alg>_init is actually the configuration of `struct wd_ctx_config` and `struct wd_sched`. Therefore, the next thing to be done is to use limited and easy-to-use input parameters to describe users' requirements on the two input parameters, ensuring that the functions of the new interface init2 are the same as those of init. For ease of description, v1 is used to refer to the existing interface, and v2 is used to refer to the layer of encapsulation. At present, at least 4 parameters are required to meet the user configuration requirements with the V1 interface function remains unchanged. @device_list: The available uacce device list. Users can get it by wd_get_accel_list(). @numa_bitmask: The bitmask provided by libnuma. Users can use this parameter to control requesting ctxs devices in the bind NUMA scenario. @ctx_nums: The requested ctx number for each numa node. Due to users may have different requirements for different types of ctx numbers, needs a two-dimensional array as input. @sched_type: Scheduling type the user wants to use. What's more, some users want uadk to provide the default value about input parameters for some performance insensitive scenes. C code has no way to. Changelog: v2->v3: - update the wd_comp_init2 parameters. v1->v2: - Update the desdescription about wd_<alg>_init in wd_design.md. Yang Shen (6): uadk - support algorithms initialization reentry protect uadk/doc - update wd_alg_init support reentrancy uadk - support return error number as pointer uadk - mv some function to header file uadk/comp - add wd_comp_init2 uadk/docs - support a simple interface for initialization Makefile.am | 4 +- docs/wd_alg_init2.md | 176 ++++++++++++++++++++++++++++ docs/wd_design.md | 5 +- include/wd.h | 54 ++++++++- include/wd_alg_common.h | 24 ++++ include/wd_comp.h | 27 +++++ include/wd_util.h | 57 +++++++++ wd.c | 97 +++++++++++++--- wd_aead.c | 33 ++++-- wd_cipher.c | 35 ++++-- wd_comp.c | 248 ++++++++++++++++++++++++++++++++++++++-- wd_dh.c | 34 ++++-- wd_digest.c | 33 ++++-- wd_ecc.c | 33 ++++-- wd_rsa.c | 33 ++++-- wd_util.c | 83 +++++++++++++- 16 files changed, 870 insertions(+), 106 deletions(-) create mode 100644 docs/wd_alg_init2.md -- 2.24.0
