Hello,
I just tried to compile 2.6.31-rc8-rt9 on amd64 and got the following compiler errors in drivers/staging:
- drivers/staging/comedi:
CC [M] drivers/staging/comedi/drivers/quatech_daqp_cs.o drivers/staging/comedi/drivers/quatech_daqp_cs.c: In function ‘daqp_interrupt’: drivers/staging/comedi/drivers/quatech_daqp_cs.c:308: error: implicit declaration of function ‘up’ drivers/staging/comedi/drivers/quatech_daqp_cs.c: In function ‘daqp_ai_insn_read’: drivers/staging/comedi/drivers/quatech_daqp_cs.c:421: error: implicit declaration of function ‘sema_init’ drivers/staging/comedi/drivers/quatech_daqp_cs.c:434: error: implicit declaration of function ‘down_interruptible’
Possible fix: #include <linux/semaphore.h> in drivers/staging/comedi/comedidev.h
- drivers/staging/rt2870: CC [M] drivers/staging/rt2870/common/2870_rtmp_init.o drivers/staging/rt2870/common/2870_rtmp_init.c: In function ‘CreateThreads’: drivers/staging/rt2870/common/2870_rtmp_init.c:754: error: implicit declaration of function ‘semaphore_init_locked’
with PREEMPT_RT semaphore_init_locked doesn't exist. The driver needs to be converted to use mutexes instead.
Hhhhm, tglx introduced these in
041e313 (staging: Bulk convert the semaphore mess)
!?
drivers/staging/rt3070/common/2870_rtmp_init.c includes ../../rt2870/common/2870_rtmp_init.c, so RT3070 has the same problem.
Just to let you know ...
Best regards Uwe
