X-BeenThere: xen-devel@lists.xen.org X-Mailman-Version: 2.1.18 Precedence: list List-Id: Xen developer discussion List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , MIME-Version: 1.0 Errors-To: xen-devel-bounces@lists.xen.org Sender: "Xen-devel" X-Virus-Scanned: ClamAV using ClamSMTP This patch implements the xl/xc changes to support set CBM for L2 CAT. The new level option is introduced to original CAT setting command in order to set CBM for specified level CAT. - 'xl psr-cat-set' is updated to set cache capacity bitmasks(CBM) for a domain according to input cache level. root@:~$ xl psr-cat-set -l2 1 0x7f root@:~$ xl psr-cat-show -l2 1 Socket ID : 0 Default CBM : 0xff ID NAME CBM 1 ubuntu14 0x7f Signed-off-by: He Chen Signed-off-by: Yi Sun Acked-by: Wei Liu --- v11: - revert change in v9 to handle the case to set both CODE and DATA for CDP at same time. This must be handled in hypervisor. v10: - fix comments. (suggested by Wei Liu) v9: - handle the case to set both CODE and DATA for CDP at same time. For such case, user does not input '-c' or '-d' to set CDP cbm. - move xl_cmdimpl.c changes into xl/xl_psr.c. - move xl_cmdtable.c changes into xl/xl_cmdtable.c. v6: - rename 'psr-cat-cbm-set' to 'psr-cat-set'. (suggested by Kevin Tian) - return 'EXIT_FAILURE' for error case. (suggested by Dario Faggioli) - print error info when input level is wrong. v4: - create this patch because of codes architecture change. --- tools/libxc/xc_psr.c | 3 +++ tools/xl/xl_cmdtable.c | 3 ++- tools/xl/xl_psr.c | 33 +++++++++++++++++++++++---------- 3 files changed, 28 insertions(+), 11 deletions(-) diff --git a/tools/libxc/xc_psr.c b/tools/libxc/xc_psr.c index 04f5927..039b920 100644 --- a/tools/libxc/xc_psr.c +++ b/tools/libxc/xc_psr.c @@ -266,6 +266,9 @@ int xc_psr_cat_set_domain_data(xc_interface *xch, uint32_t domid, case XC_PSR_CAT_L3_CBM_DATA: cmd = XEN_DOMCTL_PSR_CAT_OP_SET_L3_DATA; break; + case XC_PSR_CAT_L2_CBM: + cmd = XEN_DOMCTL_PSR_CAT_OP_SET_L2_CBM; + break; default: errno = EINVAL; return -1; diff --git a/tools/xl/xl_cmdtable.c b/tools/xl/xl_cmdtable.c index 539cb64..2c71a9f 100644 --- a/tools/xl/xl_cmdtable.c +++ b/tools/xl/xl_cmdtable.c @@ -546,11 +546,12 @@ struct cmd_spec cmd_table[] = { }, #endif #ifdef LIBXL_HAVE_PSR_CAT - { "psr-cat-cbm-set", + { "psr-cat-set", &main_psr_cat_cbm_set, 0, 1, "Set cache capacity bitmasks(CBM) for a domain", "[options] ", "-s Specify the socket to process, otherwise all sockets are processed\n" + "-l Specify the cache level to process, otherwise L3 cache is processed\n" "-c Set code CBM if CDP is supported\n" "-d Set data CBM if CDP is supported\n" }, diff --git a/tools/xl/xl_psr.c b/tools/xl/xl_psr.c index 575f4a0..7309d4f 100644 --- a/tools/xl/xl_psr.c +++ b/tools/xl/xl_psr.c @@ -490,19 +490,21 @@ int main_psr_cat_cbm_set(int argc, char **argv) char *value; libxl_string_list socket_list; unsigned long start, end; - int i, j, len; + unsigned int i, j, len; + unsigned int lvl = 3; static struct option opts[] = { {"socket", 1, 0, 's'}, {"data", 0, 0, 'd'}, {"code", 0, 0, 'c'}, + {"level", 1, 0, 'l'}, COMMON_LONG_OPTS }; libxl_socket_bitmap_alloc(ctx, &target_map, 0); libxl_bitmap_set_none(&target_map); - SWITCH_FOREACH_OPT(opt, "s:cd", opts, "psr-cat-cbm-set", 2) { + SWITCH_FOREACH_OPT(opt, "s:l:cd", opts, "psr-cat-set", 2) { case 's': trim(isspace, optarg, &value); split_string_into_string_list(value, ",", &socket_list); @@ -522,24 +524,35 @@ int main_psr_cat_cbm_set(int argc, char **argv) case 'c': opt_code = 1; break; + case 'l': + lvl = atoi(optarg); + break; } - if (opt_data && opt_code) { - fprintf(stderr, "Cannot handle -c and -d at the same time\n"); - return -1; - } else if (opt_data) { - type = LIBXL_PSR_CBM_TYPE_L3_CBM_DATA; - } else if (opt_code) { - type = LIBXL_PSR_CBM_TYPE_L3_CBM_CODE; + if (lvl == 2) + type = LIBXL_PSR_CBM_TYPE_L2_CBM; + else if (lvl == 3) { + if (opt_data && opt_code) { + fprintf(stderr, "Cannot handle -c and -d at the same time\n"); + return EXIT_FAILURE; + } else if (opt_data) { + type = LIBXL_PSR_CBM_TYPE_L3_CBM_DATA; + } else if (opt_code) { + type = LIBXL_PSR_CBM_TYPE_L3_CBM_CODE; + } else { + type = LIBXL_PSR_CBM_TYPE_L3_CBM; + } } else { type = LIBXL_PSR_CBM_TYPE_L3_CBM; + fprintf(stderr, "Input lvl %d is wrong\n", lvl); + return EXIT_FAILURE; } if (libxl_bitmap_is_empty(&target_map)) libxl_bitmap_set_any(&target_map); if (argc != optind + 2) { - help("psr-cat-cbm-set"); + help("psr-cat-set"); return 2; }
