HI,
I am using an armv5TE (mv78100)I wonder if I need to implement memory barriers in this architecture,(some people say not needed)
reason for my question is that I am facing system total freeze(now and then) and I suspect the system(freebsd) beeing on the idle loop!
Thanks
Hi qabsou,
do you want the other than the following?
DSB MCR p15,0,<Rd>,c7,c10,4DMB MCR p15,0,<Rd>,c7,c10,5
If it is true, could you tell what kind of what kind of a memory barrier which you want?
Best regards,
Yasuhiko Koumoto.
Hi,
Thanks for your attention,
I wonder if I need to implement barriers(I have total freeze problems), I wonder this becauseit is written that ARMv5TE does not have instruction optimization.
I am thinking about the problem when instructions after interrupt enable are executed before
the interrupt enable instruction, this can lead to hang on idle loop.
