Still using outlook, but will limit the line length, I hope that works for the moment. Attached is a log with the requested information, it is a little bit non-standard though. The dump code from the mm was copied in the driver and called from there, mapping the prints back to our local printf, but it should produce the same. I did this because I didn't realize the table is static. Some background on the test setup: I'm using a Broadcom reference design AP platform with an BRCM 4708 host SOC. For the AP router platform the opensource packet OpenWRT was used. Some small modifications were made to get it to work on our HW. Only one core is enabled for the moment (no time to figure out how to enable the other one). Openwrt was configured to use kernel 3.18-rc2 and the brcmfmac of the compat-wireless code was updated with our latest code (minor patches, which have been submitted already). The device used is 43602 pcie device. Some modifications to the build system were made to enable PCIE. The test is to connect with a client to the AP and run iperf (TCP). The test can run for many hours without a problem, but sometimes fails very quickly. The log: first the ring allocation info is printed. Starting at 16.124847, ring 2, 3 and 4 are rings used for device to host. In this log the failure is on a read of ring 3. Ring 3 is 1024 entries of each 16 bytes. The next thing printed is the kernel page tables. Then some OpenWRT info and the logging of part of the connection setup. Then at 1780.130752 the logging of the failure starts. The sequence number is modulo 253 with ring size of 1024 matches an "old" entry (read 40, expected 52). Then the different pointers are printed followed by the kernel page table. The code does then a cache invalidate on the dma_handle and the next read the sequence number is correct.

If the memory has an alias which is cacheable, it is possible for cache lines to get allocated via that alias, even if the alias has no explicit accesses to it. This is something which I've been going on for quite literally /years/ - mismatched cache attributes can cause unpredictable behaviour. I've had a lot of push back from people who are of the opinion that "if it works for me, then there isn't a problem" and I eventually gave up fighting the battle, especially as the ARM architecture people weakened my reasoning behind it by publishing a relaxation of the "no differing attributes" issue. This was particularly true of those who wanted to use ioremap() on system memory - and cases such as dma_init_coherent_memory(). So, I never fixed this problem in the original DMA allocator code; I basically gave up with it. It's a latent bug which did need to be fixed, and is still present today in the non-CMA case. The symptoms which you are reporting sound very much like this kind of problem - the virtual address for the memory returned by dma_alloc_coherent() will not be cacheable memory - it will have been remapped using map_vm_area(). However, there could very well be a fully cacheable lowmem mapping of that memory, which if a read (speculative or otherwise) will bring a cache line in, and because the caches are VIPT or PIPT, that cache line can be hit via the non-cacheable mapping too. What I /really/ need is more evidence of this to tell those disbelievers where to stick their flawed arguments. :) -- FTTC broadband for 0.8mile line: currently at 9.5Mbps down 400kbps up according to speedtest.net.
