Subject: bcma usage in isr context
Date: Thu, 1 Dec 2011 14:09:25 +0100	[thread overview]
Message-ID: <4ED77C85.1050705@broadcom.com> (raw)

Hi Rafał,

I am doing some final testing on our brcmsmac driver, which I tinkered
to become a bcma device driver. During testing an issue popped up in the
ISR code.

Looking into the bcma read/write functions in host_pci.c I conclude that
bcma itself does not provide protection for concurrency. Am I correct in
that? How is this solved in b43?

Gr. AvS
