From 7f744a2369a5036cadfa05575da1704f709c98bb Mon Sep 17 00:00:00 2001 From: Jeff Epler Date: Mon, 18 Nov 2019 08:22:41 -0600 Subject: Supervisor: move most of systick to the supervisor This code is shared by most parts, except where not all the #ifdefs inside the tick function were present in all ports. This mostly would have broken gamepad tick support on non-samd ports. The "ms32" and "ms64" variants of the tick functions are introduced because there is no 64-bit atomic read. Disabling interrupts avoids a low probability bug where milliseconds could be off by ~49.5 days once every ~49.5 days (2^32 ms). Avoiding disabling interrupts when only the low 32 bits are needed is a minor optimization. Testing performed: on metro m4 express, USB still works and time.monotonic_ns() still counts up --- supervisor/supervisor.mk | 1 + 1 file changed, 1 insertion(+) (limited to 'supervisor/supervisor.mk') diff --git a/supervisor/supervisor.mk b/supervisor/supervisor.mk index b2e4eb1dc..5e997ee78 100644 --- a/supervisor/supervisor.mk +++ b/supervisor/supervisor.mk @@ -10,6 +10,7 @@ SRC_SUPERVISOR = \ supervisor/shared/safe_mode.c \ supervisor/shared/stack.c \ supervisor/shared/status_leds.c \ + supervisor/shared/tick.c \ supervisor/shared/translate.c ifndef $(NO_USB) -- cgit v1.2.3
