Currently, sending an interprocessor interrupt (IPI) requires building up a message dynamically which means memory allocation. But often times, we will want to send an IPI in low level contexts where allocation is not possible which may lead to a panic(). So create a per-cpu static array for the message queue and use that instead. Further, while we have two supplemental interrupts, we are currently only using one of them. So use the second one for the most common IPI message of all -- smp_send_reschedule(). This avoids ugly contention for locks which in turn would require an IPI message ... In general, this improves SMP performance, and in some cases allows the SMP port to work in places it wouldn't before. Such as the PREEMPT_RT state where the slab is protected by a per-cpu spin lock. If the slab kmalloc/kfree were to put the task to sleep, and that task was actually the IPI handler, then the system falls down yet again. After running some various stress tests on the system, the static limit of 5 messages seems to work. On the off chance even this overflows, we simply panic(), and we can review that scenario to see if the limit needs to be increased a bit more.

This function takes an irq_handler_t function, but the prototype in the header doesn't match the function definition. This is due to the smp headers needing to avoid circular dependencies. So change the function to take a simple pointer. Signed-off-by: NGraf Yang <graf.yang@analog.com> Signed-off-by: NMike Frysinger <vapier@gentoo.org>

The common asm-generic non-atomic bitops.h defines test_bit() for us, but we need to use our own version. So redirect the definition of this func to avoid having to inline the rest of the asm-generic file. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

Rather than maintain Kconfig entries where people have to enter raw numbers and hardcode lists of addresses/pins in the driver itself, push it all to platform resources. This lets us simplify the driver, the Kconfig, and gives board porters greater flexibility. In the process, we need to also start supporting the early platform interface. Not a big deal, but it causes the patch to be bigger than a simple resource relocation. All the Blackfin boards already have their resources updated and in place for this change.

The defBF512.h header exists only to include defBF51x_base.h, and it is the only place where defBF51x_base.h is included. So move the contents of the defBF51x_base.h header into the defBF512.h header. Same situation for the other def/cdef pairs. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

The main asm/blackfin.h header will pull in mach/blackfin.h to get all the fun Blackfin defines. So having any of the sub-mach headers trying to include asm/blackfin.h makes no sense -- punt it. The mach/blackfin.h header takes care of including the part-specific def headers which in turn will include any other needed def file. Similarly, it takes care of pulling in the part-specific cdef header. So move this logic out of the blackfin.h when necessary. Further, make sure the cdef headers do not waste time including the def headers again. Since all parts need the common def/cdef headers, move this logic out of the part-specific headers and into the mach/blackfin.h file. Finally, we need to split the BF539 def header since the BF538 does not have MXVR and we don't want to expose those MMRs. So now all parts should have the same behavior: mach/blackfin.h asm/def_LPBlackfin.h part-specific def.h if ! asm asm/cdef_LPBlackfin.h part-specific cdef.h And the sub def/cdef headers only tail into what they need.

We don't want the BF533 to be different in terms of its MMR headers, so merge the FIO_FLAG helpers back into the normal place. To avoid circular dependencies with headers, turn the inline C funcs into CPP defines. Not like there will be any code size differences. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

Use the same naming convention for DMA traffic MMRs (most were legacy anyways) so we can avoid useless ifdef trees. Same goes for MDMA names -- this actually allows us to undo a bunch of ifdef redirects that existed for this purpose alone. Signed-off-by: NMike Frysinger <vapier@gentoo.org>

We're in the process of cleaning up the global Blackfin namespace, so the bfin_sir driver needs to pull in the serial header explicitly now.
