From 5112ff5a8826014962656398fb3b3043a968dc6c Mon Sep 17 00:00:00 2001 From: Joel Sherrill Date: Wed, 25 Oct 2006 11:28:08 +0000 Subject: 2006-10-25 Jennifer Averett * libcsupport/src/termios.c: Change attribute of semaphore. It was counting interrupts not acting as a condition synchronization mutex. Since the caller did not always need to obtain the semaphore, it was not being decremented until there was no data. This could occur after hours of running a system and thousands of interrupts. The code in fillBufferQueue would spin until it had consumed all of those semaphore counts. --- cpukit/libcsupport/src/termios.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'cpukit/libcsupport') diff --git a/cpukit/libcsupport/src/termios.c b/cpukit/libcsupport/src/termios.c index 1917c68735..40c8ba75a6 100644 --- a/cpukit/libcsupport/src/termios.c +++ b/cpukit/libcsupport/src/termios.c @@ -259,7 +259,7 @@ rtems_termios_open ( sc = rtems_semaphore_create ( rtems_build_name ('T', 'R', 'r', c), 0, - RTEMS_COUNTING_SEMAPHORE | RTEMS_PRIORITY, + RTEMS_SIMPLE_BINARY_SEMAPHORE | RTEMS_PRIORITY, RTEMS_NO_PRIORITY, &tty->rawInBuf.Semaphore); if (sc != RTEMS_SUCCESSFUL) -- cgit v1.2.3
