Message-Id: <1236586097-3830-1-git-send-email-qingtao.cao@windriver.com> Date: Mon, 9 Mar 2009 16:08:09 +0800 From: Harry Ciao <qingtao.cao@...driver.com> To: linux-kernel@...r.kernel.org, bluesmoke-devel@...ts.sourceforge.net Subject: [v1 PATCH 0/8] Add AMD8111 and AMD8131 EDAC drivers 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. Test steps: ----------- CONFIG_EDAC=y CONFIG_EDAC_DEBUG=y CONFIG_EDAC_MM_EDAC=m CONFIG_EDAC_AMD8111=m CONFIG_EDAC_AMD8131=m insmod edac_core.ko dmesg -n 8 insmod amd8111_edac.ko cd /sys/devices/system/edac ls -lt ls -lt pci/ ,etc ls -lt lpc/ ,etc rmmod amd8111_edac insmod amd8131_edac.ko insmod amd8111_edac.ko cd /sys/devices/system/edac ls -lt ls -lt pci/pci* ,etc rmmod amd8131_edac rmmod amd8111_edac Test results: ------------- root@...alhost:/root> insmod edac_core.ko root@...alhost:/root> lsmod Module Size Used by edac_core 83168 0 root@...alhost:/root> ls -lt /sys/devices/system/edac/ total 0 drwxr-xr-x 2 root root 0 May 1 20:52 mc root@...alhost:/root> dmesg -n 8 root@...alhost:/root> insmod amd8111_edac.ko EDAC DEBUG: edac_device_register_sysfs_main_kobj() amd8111_lpc_bridge_init: port 97 is buggy, not supported by hardware?
