Date: Wed, 11 Mar 2009 11:25:50 +0800 From: Harry Ciao <qingtao.cao@...driver.com> To: linux-kernel@...r.kernel.org, bluesmoke-devel@...ts.sourceforge.net Subject: [v2 PATCH 0/7] Add AMD8111 and AMD8131 EDAC drivers Hi, This is the v2 series of patches for EDAC AMD8111 & AMD8131 drivers. I have integrated suggestions from Bert, Greg and Andrew. Tests all passed on Maple platform, these modules could be properly loaded/unloaded, with their sysfs interfaces created/cleaned. Any suggestions are warmly welcomed! Best regards, Harry Comments: --------- Introduce AMD8111 EDAC driver, which makes use of error detections on the LPC Bridge Controller and PCI Bridge Controller on the AMD8111 HyperTransport I/O Hub. Introduce AMD8131 EDAC driver source file, which makes use of error detections on the PCI-X Bridge Controllers on the AMD8131 HyperTransport PCI-X Tunnel. Since both AMD8111 and AMD8131 EDAC drivers would use edac_pci_ctl_info structures, EDAC core has to take the responsibility to allocate a unique "edac_pci_idx" for each of them, by newly added edac_pci_alloc_index(). Note, by far only POLL mode is supported, and they have been tested on MAPLE platform, from below test logs we can tell that they could be correctly installed and removed, and export proper sysfs interfaces.
