I will agree with you on this, ONLY IF a people can represent ARM and all chip vendors say publicly: " We never ever use SBSA watchdog IP core on ARM32!" or " SBSA watchdog IP core is imcompatible with ARM32" Although the SBSA is all about ARMv8, but in "5 APPENDIX A: GENERIC WATCHDOG", it doesn't say "this is only for ARMv8". and its clock source "system counter" and arm_arch_timer have been in ARM32 Soc for years, and all the regs in SBSA watchdog is 32bit. I can't see why we can not do that, unless I miss something. I wonder why you are so sure "that SOC won't have an SBSA watchdog in it." any documentation ? Sorry, I am not a chip design engineer, I can't see why 32-bit ARM won't have an SBSA watchdog in it. > >> or run a 32-bit kernel on >> >> a chip that has it. > > > That might happen, but I would be very surprised, and I would need to be > convinced that it's useful. > > -- > Sent by an employee of the Qualcomm Innovation Center, Inc. > The Qualcomm Innovation Center, Inc. is a member of the > Code Aurora Forum, hosted by The Linux Foundation. -- Best regards, Fu Wei Software Engineer Red Hat Software (Beijing) Co.,Ltd.Shanghai Branch Ph: +86 21 61221326(direct) Ph: +86 186 2020 4684 (mobile) Room 1512, Regus One Corporate Avenue,Level 15, One Corporate Avenue,222 Hubin Road,Huangpu District, Shanghai,China 200021 -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
