[PATCH] kvm: Two-way apic tpr synchronization · 54810342

由 Dor Laor 提交于 2月 12, 2007

We report the value of cr8 to userspace on an exit.  Also let userspace change
cr8 when we re-enter the guest.  The lets 64-bit guest code maintain the tpr
correctly.

Thanks for Yaniv Kamay for the idea.

[PATCH] kvm: Fix mmu going crazy of guest sets cr0.wp == 0 · ac6c2bc5

由 Avi Kivity 提交于 2月 12, 2007

The kvm mmu relies on cr0.wp being set even if the guest does not set it.  The
vmx code correctly forces cr0.wp at all times, the svm code does not, so it
can't boot solaris without this patch.

[PATCH] kvm: Fix gva_to_gpa() · e119d117

由 Avi Kivity 提交于 2月 12, 2007

gva_to_gpa() needs to be updated to the new walk_addr() calling convention,
otherwise it may oops under some circumstances.

Use the opportunity to remove all the code duplication in gva_to_gpa(), which
essentially repeats the calculations in walk_addr().

[PATCH] ufs2 write: inodes write · 3313e292

由 Evgeniy Dushistov 提交于 2月 12, 2007

This patch adds into write inode path function to write UFS2 inode, and
modifys allocate inode path to allocate and init additional inode chunks.

Also some cleanups:
- remove not used parameters in some functions
- remove i_gen field from ufs_inode_info structure,
there is i_generation in inode structure with same purposes.

[PATCH] ufs2 write: mount as rw · cbcae39f

由 Evgeniy Dushistov 提交于 2月 12, 2007

These series of patches add UFS2 write-support.  UFS2 - is default file system
for recent versions of FreeBSD.

The main differences from UFS1 from write support point of view
are:
1)Not all inodes are allocated during formatation of disk.
2)All meta-data(pointer to data blocks) are 64bit(in UFS1 they
are 32bit).

So patch series consist of
1)make possible mount UFS2 in read-write mode
2)code to write ufs2 inodes and code to initialize inodes chunks.
3)work with 64bit meta-data

I made simple testing like create/deleting/writing/reading/truncating, also I
ran fsx-linux and untar and build kernel on UFS1 and UFS2, after that FreeBSD
fsck do not find any errors in fs.

This patch makes possible to mount ufs2 "rw", and updates UFS2 documentation:
remove note about bug(it fixed by reallocate blocks on the fly patch) and add
me in the list of people who want receive bug reports.
