Dear list, This is the V4 of the trim support for xen-blkfront/blkback, Now we move BLKIF_OP_TRIM to BLKIF_OP_DISCARD, and dropped all "trim" stuffs in the patches, and use "discard" instead. Also we updated the helpers of blkif_x86_{32|64}_request or we will meet problems using a non-native protocol. And this patch has been tested with both SSD and raw file, with SSD we will

The following series of 10 patches is a merge of the xenfb and xenconsoled functionality into the qemu-dm code. The general approach taken is to have qemu-dm provide two machine types - one for xen paravirt, the other for fullyvirt. For compatability the later is the default. The goals overall are to kill LibVNCServer, remove alot of code duplication and/or parallel impls of the same concepts, and

I am proposing these two patches for 3.2. They allow the backend to process the REQ_FUA request as well. Previous to these patches it only did REQ_FLUSH. There is also a bug-fix for the logic of how barrier/flushes were handled. The patches are based on a branch which also has ''feature-discard'' patches, so they won''t apply nativly on top of 3.1-rc5. Please review and

...'t been touched since the last copy. I have experimented and deturmined that the file size seems to be important. If the file is between 926 & 933 bytes long it will always be copied!! Other sizes and possibly other aspects of the files are causing this as well. I'm using rsync -avz otherend::something somewherelocal The same file from the same server into a Linux machine behaves exactly as it should (i.e. copied the first time only unless changed) uname -a on the W2K gives: CYGWIN_NT-5.0 FRANKNT-2 1.3.4(0.47/3/2) 2001-11-05 16:15 i686 unknown and rsync --version rsync version 2.5....

Hello, I to issue a grant on a page, but only partially. I have a pointer to somewhere in memory and need to issue the grant for such a pointer but not to the entire page. I know FLAG GTF_sub_page is used for that purpose but grant_entry_v1 apparently has no fields for sub_page, should I change the code to use Version 2 grant table entries? Thanks, Daniel -- +-=====---------------------------+

...ode segfaults without them. The USB code doesn''t need them because the entire state machine and all associated ring/shared page setup is factored out into the xenidc_endpoint object and the driver code gets connect and disconnect callbacks from the endpoint instead. I''d like the otherend_changed entrypoint to be optional please. This will also let me remove the MixedCaps XenbusState typename from my code :-) I took the opportunity to implement suspend and resume in the frontend (and the backend to keep the code equivalent) though this is currently untested.

This is an update to the Linux part of the Xen PVFB. Linux Xen PVFB is a pair of Xen para-virtual frontend device drivers: drivers/video/xen-fbfront.c provides a framebuffer, and drivers/input/xen-kbdfront provides keyboard and mouse. Their backends run in dom0 user space. Parts in this patch series: 1. Enable Xen console by default in domU 2. Pointer z-axis (mouse wheel) support 3. Module
