From 7ee59313932398aa2781503d25154c56301b9b73 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Fri, 1 Jun 2018 07:11:12 +0200 Subject: Remove Clock_driver_support_shutdown_hardware() The aim of this clock driver hook was to stop clock tick interrupts at some late point in the exit() procedure. The use of atexit() pulls in malloc() which pulls in errno. It is incompatible with the intention of the CONFIGURE_DISABLE_NEWLIB_REENTRANCY configuration option. The exit() function must be called from thread context, so accompanied clock tick interrupts should cause no harm. On the contrary, someone may assume a normal operating system operation, e.g. working timeouts. Remove the Clock_driver_support_shutdown_hardware() clock driver hook. Close #3436. --- bsps/m68k/mcf52235/clock/clock.c | 8 -------- 1 file changed, 8 deletions(-) (limited to 'bsps/m68k/mcf52235/clock/clock.c') diff --git a/bsps/m68k/mcf52235/clock/clock.c b/bsps/m68k/mcf52235/clock/clock.c index a879a770b1..d5e1817536 100644 --- a/bsps/m68k/mcf52235/clock/clock.c +++ b/bsps/m68k/mcf52235/clock/clock.c @@ -52,14 +52,6 @@ static void mcf52235_tc_tick(void) #define Clock_driver_support_install_isr( _new ) \ set_vector(_new, CLOCK_VECTOR, 1) -/* - * Turn off the clock - */ -#define Clock_driver_support_shutdown_hardware() \ - do { \ - MCF_PIT1_PCSR &= ~MCF_PIT_PCSR_EN; \ - } while (0) - /* * Set up the clock hardware * -- cgit v1.2.3
