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 t...

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 bios_loa...

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 seabios.

Hi all, I have some puzzle about hvmloader in the path /tools/firmware/, they are: 1: Is hvmloader running in non-root mode? 2: If hvmloader runs in non-root mode, does it have its pagetable? when set GUEST_CR3 in vmcs? 3: How can I find the value of GUEST_RIP in vmcs is set to the entry point of hvmloader,when virtual machine do it first v...

Currently it is assumed PCI device BAR access < 4G memory. If there is such a device whose BAR size is larger than 4G, it must access > 4G memory address. This patch enable the 64bits big BAR support on hvmloader. v3 changes from v2: - Remain original print information v2 changes from v1 as comments by Jan. 1) Set Dynamic MMIO high memory address instead of a fixed number 640G 2) Mask bar_sz earlier to avoid older code changes 3) Add bar size barrier to judge high memory resource 4) Clean up bar64_reloca...

...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 (default=1). These result in population of new platform/acpi_s3 and platform/acpi_s4 xenstore keys. hvmloader then reads these keys to determine whether or not to include SSDTs containing the _S3 and _S4 packages respectively. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

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 is the bios entry,so I think the virtual bios in hvmloader will...

Hi, I have 3.0.4-1 testing downloaded a week ago. I have enabled VT in the bios and rebuilt xen, but for some reason hvmloader does not get compiled and built. Under xen/tools/firmware I see hvmloader and when I try and do a make it complains of Install dev86 package to build firmware! (http://www.cix.co.uk/~mayday) Why is the hvmloader not built as part of Xen. I am using x86_64bit. Can someone help me to fi...

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.

The vast majority of the code is in second patch. The first patch merely changes the xenstore key name used by hvmloader to store the buffer address.

...ADDR package. Patch 2 adds ctype infrastructure to hvloader in preparation for... Patch 3 adds all the code to plumb the value of a new ''generation_id'' parameter in the VM config through to the VM generation id buffer at VM boot time. Patch 4 adds an implementation of sprintf() to hvmloader. Patch 5 adds an implementation of xenstore-write to hvmloader. Patch 6 adds support for tracking the address of the VM generation id buffer (via xenstore) across save/restore or migrate and updating the value of the buffer with the value from the VM config file.
