Patch merged into coreboot/master: southbridge/amd/sr5650: Add MCFG ACPI table support
by gerrit＠coreboot.org 18 Dec '15

18 Dec '15

the following patch was just integrated into master: commit 1eaaa0e446b88e0ad60c4b6f68a022a9184f1df8 Author: Timothy Pearson <tpearson(a)raptorengineeringinc.com> Date: Fri Aug 14 15:20:42 2015 -0500 southbridge/amd/sr5650: Add MCFG ACPI table support As the southbridge largely controls the PCI[e] configuration space this patch moves the resource allocation from the northbridge to the southbridge when the extended configuration space region is enabled.

Patch merged into coreboot/master: drivers/pc80: Add optional spinlock for nvram CBFS access
by gerrit＠coreboot.org 18 Dec '15

18 Dec '15

the following patch was just integrated into master: commit 7b22d84d55386ee422fa77c1d8bce9dddeaaa231 Author: Timothy Pearson <tpearson(a)raptorengineeringinc.com> Date: Fri Aug 28 19:52:05 2015 -0500 drivers/pc80: Add optional spinlock for nvram CBFS access When enabling the IOMMU on certain systems dmesg is spammed with I/O page faults like the following: AMD-Vi: Event logged [IO_PAGE_FAULT device=00:14.0 domain=0x000a address=0x000000fdf9103300 flags=0x0030] Decoding the faulting address: 0x000000fdf9103300 fdf91x Hypertransport system management region 33 SysMgtCmd (System Management Command) = 0x33 3 Base Command Type = 0x3: STPCLK (Stop Clock request) 3 SMAF (System Management Action Field) = [3:1] = 0x1 1 Signal State Bit Map = [0] = 0x1 Therefore, the error appears to be triggered by an upstream C1E request. This was eventually traced to concurrent access to the SP5100's SPI Flash controller by multiple APs during startup. Calls to the nvram read functions get_option and read_option call CBFS functions, which in turn make near-simultaneous requests to the SPI Flash controller, thus placing the SP5100 in an invalid state. This limitation is not documented in any public AMD errata, and was only discovered through considerable debugging effort.
