similar to: [PATCH] [Firmware] TCG BIOS extensions for the Bochs BIOS

This patch adds TCG BIOS extensions to the high memory area along with some often-used libc utility functions. The TCG extensions are described here: https://www.trustedcomputinggroup.org/specs/PCClient/TCG_PCClientImplementationforBIOS_1-20_1-00.pdf I have tried to keep the patching with rombios.c to a minimum, but some amount of code needs to be inserted at various locations. The code is

Hello, I found out what the problem in my other thread was, now I need to solve it: I need to port a modified Bochs bios to Xen x86. However, a file of the original source seems missing: acpi-dsdt.hex. It''s neither in the tools/firmware/hvmloader/acpi directory nor in the tools/firmware/rombios one. Also applying the diffs or manually editing the source probably won''t work since

Hi, when I boot my windows, the bios that is used is a qemu bios. I''m searching for the bios file on my system that is used by the hvmloader. I found bios files from bochs : -rw-r--r-- 1 root root 131072 2008-06-28 03:05 /usr/share/bochs/BIOS-bochs-latest -rw-r--r-- 1 root root 65536 2008-06-28 03:05 /usr/share/bochs/BIOS-bochs-legacy -rw-r--r-- 1 root root 131072 2008-06-28 03:05

This patch set mainly allows the user to build a seabios or rombios only version of hvmloader. In addition, when building a seabios only hvmloader, Option ROMs like vgabios and etherboot are no longer required, and therefore can be disabled from the build. Dependency on the bcc compiler can also be avoided the same way. v2: Separate patches for separate issues Introduced config option to

This patch adds a TPM device model to the qemu dm for fully virtualized VMs. It is enabled in the VM only if the user requests a TPM device in the vm configuration file using the ''vtpm=[...]'' line. It enables the qemu device model command line with a ''vtpm_instance <instance number>'' parameter. Signed-off-by: David Safford <safford@watson.ibm.com>

Attached simple patch modifies the rombios and hvmloader Makefiles to default to an 8-way bochs bios for the hvmloader. Is there a reason to not define the mp config table by default for >1 processors (8), in the repository? Seems like using the hvm guest config file can the methodolody to describe a UP guest regardless of the mptables. Defaulting the rombios to MP would allow users to

I have a self built system using an Intel D 920 processor and a MB that supports VT. I''m able to run HVM domains fine, but have trouble getting multiple VCPUs for these domains. Here is an example of one of my configs. # -*- mode: python; -*- #============================================================================ # Python configuration setup for ''xm create''. #

Some firmware, such as OVMF relies on this value to get the size of extra memory above 4GB. Seabios in Xen doesn''t need this as it gets e820 directly from Xen. Rombios doesn''t read this value.

When booting HVMs with SeaBIOS, the BIOS itself takes care of extracting option ROMs from the PCI devices. These ROMs are usually provided with by the device model (qemu). Thus, hvmloader should not require any longer the rombios, stdvga, cirrusvga or etherboot ROMs to be present. Also, the 32bitbios_support.c file is specific to rombios and should not be built when building hvmloader with

This patch supports basic gfx passthrough on QEMU: - disable emulated VGA adpater if there is passthroughed gfx - register/unregister legacy VGA I/O ports and MMIOs for passthroughed gfx Signed-off-by: Ben Lin <ben.y.lin@intel.com> Signed-off-by: Weidong Han <weidong.han@intel.com> _______________________________________________ Xen-devel mailing list

This patch series adds the ability to selectively disable the S3 and S4 ACPI power states for HVM guests. Since there is a general move towards retiring the hvm_info_table structure, the first patch moves the acpi_enabled flag out of the hvm_info_table and into a xenstore key (platform/acpi). The second patch then introduces the acpi_s3 and acpi_s4 configuration parameters to the xl config file

Hi, when user create the virtual machine, then: which code execute firstly, hvmloaer or qemu-dm?I have traced the codes flow and found qemu-dm run before hvmloader,right? And virtual bios code are both in hvmloader and qemu-dm, but I think it should be only one of virtual bios will be used to initialize the virutal device in qemu-dm.I find at the end of hvmloader it will jmp to 0xffff0, that

Hi, These set of patches are affected by replacing bios_relocate hook with bios_load hook in hvmloader. The patches for code files config.h and hvmloader.c also contains part of the contents of Enabling UEFI BIOS(OVMF) support in Xen-unstable HVM. Is there any problem with these patches? Thank you very much. # HG changeset patch # User gbtju85@gmail.com # Replace bios_relocate hook with

A "main" function is defined in Xen-3.1.0-source/tools/firmware/hvmloader/hvmloader.c. In this main function, rombios, vgabios and vmxassist are copied to specified address, with following commands memcpy((void *)ROMBIOS_PHYSICAL_ADDRESS, rombios, rombios_sz); ... memcpy((void *)ETHERBOOT_PHYSICAL_ADDRESS, etherboot, sizeof(etherboot)); .... But after searching the whole

This patch adds a TIS device model compliant to the 1.2 TPM specification to Qemu. It implements all registers necessary to make the Linux TIS driver work (tpm_tis.c). All of the basic registers supported by this type of device are implemented. Also the locality selection has been implemented, but has not been tested. The legacy registers as described in the specification are not supported.

Thank you. I notice the system then jumps to F000:FFF0 to execute. But because VMX is turned on, switching to real-mode would incur problems? I don’t find any clue to turn on the vm86 mode as Readme in the tools/firmware directory puts.

Hello list, I''ve installed Xen 3.0.3-testing from source on my spiffy new socket AM2 machine and I''m eager to play with fully virtualized guests. The problem is, it seems the hvmloader wasn''t installed (or built) when I built and installed Xen. I''m getting the following error : Error: Kernel image does not exist: /usr/lib/xen/boot/hvmloader So I did a quick

Since the vTPM implementations are being incorproated into Xen and possibly upstream Linux, I would like to see if this protocol change could be added before we have significant legacy implementations. If not, I still think it would be useful as either a v2 or negotiated protocol change. The current vTPM protocol is a copy of the network protocol. This was likely done for ease of implementation,

This bug, at its core, is that currently there is no supported solution for VGA passthrough on Xen for stable version Jessie from Debian. After browsing Xen's repositories, I found out that Xen did not claim to support VGA passthrough with the upstream qemu-xen device model until Sep 25, 2015, the date the xl.cfg man page was updated to indicate support for VGA passthrough with upstream
