#95: Run coreboot in VirtualBox

#95: Run coreboot in VirtualBox ---------------------------------+------------------------------------------ Reporter: uwe | Owner: somebody Type: defect | Status: new Priority: minor | Milestone: Component: misc | Version: Keywords: | Dependencies: Patchstatus: there is no patch | ---------------------------------+------------------------------------------ It would be nice if we could test coreboot images in VirtualBox, see http://virtualbox.org/. VirtualBox does not (yet) provide a simple mechanism to use a different BIOS in their emulated machines (something like "-L" in qemu). Instead the BIOS image (a custom bochs BIOS + LGPL'g VGABIOS) is converted to C code (an array of bytes, or the like) and merged into the VirtualBox executable. The relevant files are {{{ src/VBox/Devices/PC/DevPcBios.cpp bldprogs/bin2c.c }}} if someone want to hack VirtualBox to easily support using coreboot images instead of their usual BIOS. -- Ticket URL: <http://tracker.coreboot.org/trac/coreboot/ticket/95> coreboot <http://www.coreboot.org/>

EHCI debug port finder
by Carl-Daniel Hailfinger May 30, 2014

May 30, 2014

I wanted to know which physical port of my multiple USB controllers have the debug capability. There was no way to find that easily, so I created a tool which will do most of the work for the user. Example output: The following PCI devices support a USB debug port (says lspci): 0000:00:1d.7 The following PCI devices support a USB debug port (says the kernel): 0000:00:1d.7 PCI device 0000:00:1d.7, USB bus 3, USB physical port 1 Currently connected high-speed devices: /: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=ehci_hcd/6p, 480M |__ Port 2: Dev 20, If 0, Class=stor., Driver=usb-storage, 480M The output can be improved, but it's a good start.

#110: Allow for per-device subsystem IDs

#110: Allow for per-device subsystem IDs ---------------------------------+------------------------------------------ Reporter: uwe | Owner: somebody Type: enhancement | Status: new Priority: minor | Milestone: Component: coreboot | Version: v3 Keywords: | Dependencies: Patchstatus: there is no patch | ---------------------------------+------------------------------------------ Currently both v2 and v3 only allow us to use one global set of PCI subsystem IDs, which is too simplistic. In theory (and often in practice) each PCI device has (or can have) its own subsystem ID. We should fix this, at least in v3, possibly also in v2.

flashrom patch: add support for Abit AB-BM6 board
by Tim ter Laak Sept. 13, 2010

Sept. 13, 2010

Hello all, This patch adds support for the Abit AB-BM6 mainboard to flashrom. The biggest part is a generic function to lower a GPIO line on the PIIX4E southbridge, copied and adapted from its ich_gpio_raise() counterpart (mostly lower instead of raise, followed names from the PIIX4E datasheet). The board specific function then uses this to lower GPO 26. Signed-off-by: Tim ter Laak <timl(a)scintilla.utwente.nl> --- The patch was made from the flashrom subdir, because svn diff from the top-level coreboot dir (as per the directions in the Development Guidelines on the wiki) didn't seem to work for me. Probably because flashrom is fetched externally when checking out coreboot? Anyway, I hope this is okay. If you really prefer a diff from the top-level dir just let me know, and I'll regenerate it with gnu diff. Kind regards, Tim.
