If a current kernel, e.g., v4.7, still fails, can you post the complete dmesg log and contents of /proc/iomem?

Hello Bjorn, thank you for the quick response. I suppose I should have previously mentioned that I had also tested this on a v4.4 kernel, but I went ahead and tested on the v4.7-rc7 branch and experienced the same behavior. > If a current kernel, e.g., v4.7, still fails, can you post the > complete dmesg log and contents of /proc/iomem? dmesg log: [ 0.000000] Booting Linux on physical CPU 0x0 [ 0.000000] Linux version 4.7.0-rc7 (rjones@rjones) (gcc version 4.8.3 (OpenWrt/Linaro GCC 4.8-2014.04 r42297) ) #52 SMP Mon Sep 19 13:16:27 PDT 2016 [ 0.000000] CPU: ARMv7 Processor [412fc09a] revision 10 (ARMv7), cr=10c5387d [ 0.000000] CPU: PIPT / VIPT nonaliasing data cache, VIPT aliasing instruction cache [ 0.000000] Machine model: Gateworks Ventana i.MX6 Dual/Quad GW54XX [ 0.000000] cma: Reserved 16 MiB at 0x4f000000 [ 0.000000] Memory policy: Data cache writealloc [ 0.000000] On node 0 totalpages: 262144 [ 0.000000] free_area_init_node: node 0, pgdat c0e6bbc0, node_mem_map ef7f8000 [ 0.000000] Normal zone: 1536 pages used for memmap [ 0.000000] Normal zone: 0 pages reserved [ 0.000000] Normal zone: 196608 pages, LIFO batch:31 [ 0.000000] HighMem zone: 65536 pages, LIFO batch:15 [ 0.000000] percpu: Embedded 13 pages/cpu @ef795000 s24448 r8192 d20608 u53248 [ 0.000000] pcpu-alloc: s24448 r8192 d20608 u53248 alloc=13*4096 [ 0.000000] pcpu-alloc: [0] 0 [0] 1 [0] 2 [0] 3 [ 0.000000] Built 1 zonelists in Zone order, mobility grouping on.

Greetings, I'm looking into a PCI resource limitation issue on an IMX6 based board and I find that in the 3.14 kernel I am able to use 6 Ath10k devices with the following resources: 03:00.0 Network controller: Qualcomm Atheros QCA986x/988x 802.11ac Wireless Network Adapter Flags: fast devsel, IRQ 155 Memory at 01200000 (64-bit, non-prefetchable) [disabled] [size=2M] [virtual] Expansion ROM at 01100000 [disabled] [size=64K] Capabilities: [40] Power Management version 2 Capabilities: [50] MSI: Enable- Count=1/8 Maskable+ 64bit- Capabilities: [70] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [140] Virtual Channel Capabilities: [160] Device Serial Number 00-00-00-00-00-00-00-00 In the 3.15 kernel following commit (5b28541552ef5eeffc41d6936105f38c2508e566), allocation has changed in such a way that results in none of the 6 radios nor the pci based ethernet interface being mapped. I am very new to PCI but after fiddling with some of the changes in the aforementioned commit I was able to come up with a 1 line patch that allows all 6 radios to once again become mapped and usable on the IMX6. The patch contents being: if (r == &ioport_resource || r == &iomem_resource) I understand that this blatantly ignores the type mask parameter and would greatly appreciate any insight that you can provide as far as the proper way to proceed. Note that the IMX6 has a limited memory window (16M) between the PCI core and the memory controller. This is mapped as: 512KB config space 64KB io space 15MB mem space available for devices Best Regards, Robert -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
