Linux Kernel https://git.stealer.net/cgit.cgi/user/sven/linux.git/atom?h=v4.9.2 2016-02-26T16:53:06Z 2016-02-26T16:53:06Z Arnd Bergmann arnd@arndb.de 2015-12-07T14:46:59Z urn:sha1:cc0336ec8a0cc7f83588019850ebe97df32c304c The knav_qmss driver is currently broken when CONFIG_LPAE is set, which is a bit surprising because I'd expect that any serious users of this platforms would have more than 2GB of RAM and require LPAE. The compiler clearly warns about an incorrect use of dma_addr_t in the debug kernel messages: ti/knav_qmss_queue.c: In function 'knav_queue_setup_region': ti/knav_qmss_queue.c:1025:117: warning: format '%x' expects argument of type 'unsigned int', but argument 9 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=] ti/knav_qmss_queue.c:1025:117: warning: format '%x' expects argument of type 'unsigned int', but argument 10 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=] ti/knav_qmss_queue.c: In function 'knav_queue_setup_link_ram': ti/knav_qmss_queue.c:1175:118: warning: format '%x' expects argument of type 'unsigned int', but argument 4 has type 'dma_addr_t {aka long long unsigned int}' [-Wformat=] This patch changes all the debugging output to use the correct %pad format string that works with both 32-bit and 64-bit dma_addr_t. As the variable naming is somewhat confusing here, I also change all *_phys names to *_dma when they refer to bus addresses that are used for DMA rather than a physical memory address as seen from the CPU. This is particularly important on keystone, because the two things are not the same there.

This driver is responsible for actually booting the wkup_m3_rproc and also handling all IPC which is done using the IPC registers in the control module, a mailbox, and a separate interrupt back from the wkup_m3. A small API is exposed for executing specific power commands, which include configuring for low power mode, request a transition to a low power mode, and status info on a previous transition.

Currently hwqueue driver configures linking RAM(s) to be used cooperatively by the QMs (shared mode). Therefore if both queue managers are used then both must be configured with exactly the same linking RAM info (base address and size) independent of the number of linking RAM(s) specified in the device tree. For proper operation only one linking RAM is required and in most cases this can be internal one as long as it is able to handle the number of descriptors used in the system. Current driver code however skips configuration of second queue manager if second linking RAM is not specified. If the configuration for the QM2 is missing there will be a crash when it tries to push/pop descriptors from its queues.
