[PATCH 0/4] Use 'struct pci_device' to limit option rom execution.

by Kevin O'Connor

This patch series extends the proliferation of 'struct pci_device' which was introduced in the last patch series. The objective of this series is to ensure that ATA devices configured to use the native ATA driver don't attempt to run an option rom on the device. This can become complex when a device that isn't identified as a PCI_CLASS_STORAGE_IDE uses the native ATA driver. So, a bit in the 'struct pci_device' now notes when a native driver is in use and the option rom code checks for it. Gerd - this patch series (and the previous one) may conflict with your work. Kevin O'Connor (4): Use manual PCI search when making bios ram writable. Move pci_probe() call into pciinit() code. Convert pci_init_device to use 'struct pci_device'. Use 'struct pci_device' to note which devices have native drivers. src/acpi.c | 16 ++++++------ src/ata.c | 14 ++++++---- src/optionroms.c | 4 +-- src/pci.c | 33 +++++++++++--------------- src/pci.h | 11 ++++++-- src/pciinit.c | 69 ++++++++++++++++++++++++++++++++---------------------- src/post.c | 1 - src/shadow.c | 41 ++++++++++++++------------------ src/smm.c | 6 ++-- 9 files changed, 101 insertions(+), 94 deletions(-) -- 1.7.4.4

[PATCH 0/2] Boot up with a splash picture configurable,

by Wayne Xia

Patch description: There are 2 patches, patch 1 would add a bmp decoder to enable seabios show bmp file, patch 2 will make the splash time configurable. Main purpose of this patch is: 1 Enable seabios showing a logo picture when start up without menu option. 2 Added a bmp showing module to show 24bpp bmp file as an option, for better visual effect than old jpeg decoder. 3 Make the showing time configurable by qemu, when it equals 0, directly boot up. 4 added a function to adjust data format, both used by jpeg decoder and bmp module. Currently I passed the variable Splash_time from a romfile, named "qemu_extra_params_fw.cfg", I think more variable could be simply packed inside this file in the future, not only for the splash_time value. -- Best Regards Wayne Xia mail:xiawenc@linux.vnet.ibm.com tel:86-010-82450803
