I'd not work with MSI
Hi,
I can also give back some info, might be interesting for someone. I tried
AR9382 and enabled MSI and got some results of WiFi scan (but not all networks
were found). The number of interrupts per scan in the same environment was much
smaller than the number when using legacy INTa over PCIE.
Hello,
I have tried the same thing as you did on Freescale P1020 processor (Power
architecture) using 2.6.39.1 and I am getting some results when performing
scanning.
Before enabling MSI in ath9k pci.c, I newer got any scan results. But now when
enabled I am getting at least 1 network very
I'd not work with MSI and our Atheros based hardware do not require it. I only
have a AR9380 based card and done some tests on standard PC for Sucheta ROY.
I haavn't much knowlege how the MSI is processed in Linux kernel, but it seems
not working with AR9380 without some special setup in hardware.

Hi,
Whatever you have done looks OK to me. Can you please let me know:
1. #define AR_PCIE_MSI and #define AR_PCIE_MSI_ENABLE part in reg.h file.
#define AR_PCIE_MSI(AR_SREV_9300_20_OR_LATER(ah) ? 0x40a4 : 0x4094)
Hi,
I believe you have AR9380 card installed in your PC?
You have to build your kernel with CONFIG_PCI_MSI option enabled.
CONFIG_PCI_MSI Depends on: PCI [=y] ARCH_SUPPORTS_MSI [=y]. Also you have
to include
int pci_enable_msi(struct pci_dev *dev) function in pci.c file of ath9k. This

Hi,
I have an AR9382 card (SparkLAN WPEA-121N, 168c:3116 ) in an Lenovo R500
laptop. pci_enable_msi returns zero, and the card seems to work fine.
There are lspci outputs below. Hope that helps.
lspci output without pci_enable_msi:
03:00.0 Network controller: Atheros

Hi,
Thanks a lot for your efforts. It's great news for me.
After you enable pci_enable_msi have you checked cat /proc/interrupts?
What does it show? And do you confirm that the WiFi card works
successfully
that is able to scan WiFi networks after
10 matches
