[PATCH v3 0/3] usb: add xhci support
by Gerd Hoffmann 04 Nov '13

04 Nov '13

Hi, Next version of the xhci support patch series. Changed xhci device list to use standard hlist macros. Delete devices from list in disconnect() callback, so we should not have inactive/freed devices in the list. cheers, Gerd Gerd Hoffmann (3): uas: add (temporary) superspeed stopgap usb: add usb_update_pipe() usb: add xhci support Makefile | 2 +- src/Kconfig | 6 + src/pci_ids.h | 1 + src/usb-uas.c | 4 + src/usb-xhci.c | 1124 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++ src/usb-xhci.h | 144 ++++++++ src/usb.c | 35 +- src/usb.h | 17 +- 8 files changed, 1320 insertions(+), 13 deletions(-) create mode 100644 src/usb-xhci.c create mode 100644 src/usb-xhci.h -- 1.8.3.1

[PATCH] tools/kconfig/{m,n}conf.c: Fix typo »This interface let*s*«
by Paul Menzel 03 Oct '13

03 Oct '13

Date: Mon, 4 Mar 2013 12:56:56 +0100 When Kconfig was introduced in SeaBIOS with commit a4c5daf0e2545361fadcad3015e10f8b23e53926 Author: Kevin O'Connor <kevin(a)koconnor.net> Date: Mon Jan 24 22:13:58 2011 -0500 Initial commit of Kconfig build tool. this typo was copied from Kconfig in Linux v2.6.38-rc2. In the meantime Linux commit »kconfig: nconf: rewrite help texts« (0b616500) [1] rewrote the texts for `nconf.c` – which might be ported too to SeaBIOS – and the typo was fixed there. But it is still present in `mconf.c` as of Linux 3.8.

[PATCH v6 0/3] seabios: load acpi tables from qemu
by Michael S. Tsirkin 30 Sep '13

30 Sep '13

This is the seabios code that adds support for loading acpi tables from QEMU. Changes from v5: - address Kevin's comments: move code to find rsdp to biostables.c scan for RSDP at 0x10 intervals Changes from v4: - address Kevin's comments: move loader to src/fw/ simplify some code drop some unused code chunks load from ROM even if !ACPI rename option to make it non ACPI specific Changes from v3: - updated to latest bits - add option to disable loading from QEMU Changes from v2: - addressed comments from Kevin: fixed coding style, minimized changes to existing code Changes from v1: - simplified linker interfaces along the lines suggested by Kevin - fixed lots of bugs Michael S.

Easy to add time stamps?
by Paul Menzel 30 Sep '13

30 Sep '13

Dear SeaBIOS folks, both coreboot and GRUB 2 (from Bazaar) currently allow to record time stamps, for example for benchmarking. SeaBIOS seems to have a clock implementation in `src/clock.c` already, which is also used for threading, I guess. Could that be used for time stamps too or is there something in SeaBIOS, that would cause problems? I would like to know how much time, SeaBIOS takes to execute, how long it takes for block devices to be discovered and how long the VGA option ROM takes to be executed for example. Thanks, Paul

[PATCH 0/3] add option to generate small bios
by Michael S. Tsirkin 29 Sep '13

29 Sep '13

This adds an option to generate a small bios, so that it's easy for people who want to generate binary compatible with QEMU 1.6 and earlier (which used a 128K buffer). Default is 256K (for future QEMU). Michael S.

[PATCH 0/4] Move more hardware definitions to hw/ sub-directory
by Kevin O'Connor 29 Sep '13

29 Sep '13

This series moves some additional hardware driver code from the main src/ directory to files in the src/hw/ directory. This is a minor cleanup to gather more hardware driver code together. This series is also at: https://github.com/KevinOConnor/seabios/tree/testing -Kevin Kevin O'Connor (4): Move PIT setup from clock.c to hw/timer.c.

SeaBIOS will try to wait for space in the serial buffer when it reports that it is full. If you don't actually have a serial port, or if the serial port thinks it is blocked, then it could cause a delay. -Kevin
