Hi Kiran, Thank you for the patch! Perhaps something to improve: [auto build test WARNING on bluetooth-next/master] [also build test WARNING on next-20200611] [cannot apply to bluetooth/master v5.7] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system. BTW, we also suggest to use '--base' option to specify the base tree in git format-patch, please see https://stackoverflow.com/a/37406982] url: https://github.com/0day-ci/linux/commits/Kiran-K/Add-support-for-new-gene... base: https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git master config: nds32-randconfig-r014-20200612 (attached as .config) compiler: nds32le-linux-gcc (GCC) 9.3.0 reproduce (this is a W=1 build): wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross chmod +x ~/bin/make.cross # save the attached .config to linux build tree COMPILER_INSTALL_PATH=$HOME/0day COMPILER=gcc-9.3.0 make.cross ARCH=nds32 If you fix the issue, kindly add following tag as appropriate Reported-by: kernel test robot <lkp(a)intel.com&gt; All warnings (new ones prefixed by >>, old ones prefixed by <<): In file included from ./arch/nds32/include/generated/asm/bug.h:1, from include/linux/bug.h:5, from include/linux/thread_info.h:12, from include/asm-generic/preempt.h:5, from ./arch/nds32/include/generated/asm/preempt.h:1, from include/linux/preempt.h:78, from include/linux/spinlock.h:51, from include/linux/seqlock.h:36, from include/linux/time.h:6, from include/linux/stat.h:19, from include/linux/module.h:13, from drivers/bluetooth/btintel.c:9: include/linux/dma-mapping.h: In function 'dma_map_resource': arch/nds32/include/asm/memory.h:82:32: warning: comparison of unsigned expression >= 0 is always true [-Wtype-limits] 82 | #define pfn_valid(pfn) ((pfn) >= PHYS_PFN_OFFSET && (pfn) < (PHYS_PFN_OFFSET + max_mapnr)) | ^~ include/asm-generic/bug.h:139:27: note: in definition of macro 'WARN_ON_ONCE' 139 | int __ret_warn_once = !!(condition); | ^~~~~~~~~ include/linux/dma-mapping.h:352:19: note: in expansion of macro 'pfn_valid' 352 | if (WARN_ON_ONCE(pfn_valid(PHYS_PFN(phys_addr)))) | ^~~~~~~~~ drivers/bluetooth/btintel.c: At top level: drivers/bluetooth/btintel.c:229:6: warning: no previous prototype for 'btintel_boot_info' [-Wmissing-prototypes] 229 | void btintel_boot_info(struct hci_dev *hdev, | ^~~~~~~~~~~~~~~~~ drivers/bluetooth/btintel.c:252:6: warning: no previous prototype for 'btintel_boot_info_tlv' [-Wmissing-prototypes] 252 | void btintel_boot_info_tlv(struct hci_dev *hdev, | ^~~~~~~~~~~~~~~~~~~~~ << from drivers/bluetooth/btintel.c:9: 385 | bool btintel_get_fw_name(struct intel_version *ver, | ^~~~~~~~~~~~~~~~~~~ << from drivers/bluetooth/btintel.c:9: 439 | void btintel_get_fw_name_tlv(struct intel_version_tlv *ver, | ^~~~~~~~~~~~~~~~~~~~~~~ vim +/btintel_get_fw_name +385 drivers/bluetooth/btintel.c 384 386 struct intel_boot_params *params, 387 char *fw_name, size_t len, 388 const char *suffix) 389 { 390 /* This is for legacy HCI_Intel_Read_Version command. 391 * 392 * With this Intel bootloader only the hardware variant and device 393 * revision information are used to select the right firmware for SfP 394 * and WsP. 395 * 396 * The firmware filename is ibt-<hw_variant>-<dev_revid>.sfi. 397 * 398 * Currently the supported hardware variants are: 399 * 11 (0x0b) for iBT3.0 (LnP/SfP) 400 * 12 (0x0c) for iBT3.5 (WsP) 401 * 402 * For ThP/JfP and for future SKU's, the FW name varies based on HW 403 * variant, HW revision and FW revision, as these are dependent on CNVi 404 * and RF Combination. 405 * 406 * 17 (0x11) for iBT3.5 (JfP) 407 * 18 (0x12) for iBT3.5 (ThP) 408 * 409 * The firmware file name for these will be 410 * ibt-<hw_variant>-<hw_revision>-<fw_revision>.sfi. 411 * 412 */ 413 414 switch (ver->hw_variant) { 415 case 0x0b: /* SfP */ 416 case 0x0c: /* WsP */ 417 snprintf(fw_name, len, "intel/ibt-%u-%u.%s", 418 le16_to_cpu(ver->hw_variant), 419 le16_to_cpu(params->dev_revid), 420 suffix); 421 break; 422 case 0x11: /* JfP */ 423 case 0x12: /* ThP */ 424 case 0x13: /* HrP */ 425 case 0x14: /* CcP */ 426 snprintf(fw_name, len, "intel/ibt-%u-%u-%u.%s", 427 le16_to_cpu(ver->hw_variant), 428 le16_to_cpu(ver->hw_revision), 429 le16_to_cpu(ver->fw_revision), 430 suffix); 431 break; 432 default: 433 return false; 434 } 435 return true; 436 } 437 EXPORT_SYMBOL_GPL(btintel_get_fw_name); 438 440 char *fw_name, size_t len, 441 const char *suffix) 442 { 443 /* This is for legacy HCI_Intel_Read_Version command. 444 * The firmware file name for these will be 445 * ibt-<cnvi_top type+cnvi_top step>-<cnvr_top type+cnvr_top step> 446 * 447 * Currently the supported hardware variants are: 448 * iBT4.2 23 (0x17) for TyP 449 * iBT4.2 24 (0x18) for Solar 450 */ 451 snprintf(fw_name, len, "intel/ibt-%04x-%04x.%s", 452 INTEL_CNVX_TOP_PACK_SWAB(INTEL_CNVX_TOP_TYPE(ver->cnvi_top), 453 INTEL_CNVX_TOP_STEP(ver->cnvi_top)), 454 INTEL_CNVX_TOP_PACK_SWAB(INTEL_CNVX_TOP_TYPE(ver->cnvr_top), 455 INTEL_CNVX_TOP_STEP(ver->cnvr_top)), 456 suffix); 457 } 458 EXPORT_SYMBOL_GPL(btintel_get_fw_name_tlv); 459 --- 0-DAY CI Kernel Test Service, Intel Corporation https://lists.01.org/hyperkitty/list/kbuild-all@lists.01.org
