| * [BUILDER]: Initialize code segment selectors in virtual IDT to 0.Ian Campbell2007-03-081-26/+4
| | | | | | | | | | | | | | | | | | | | These should not be set until the guest kernel kernel configures an entry point otherwise the null_trap_bounce() check gets confused. This change was made to the old domain builder in 12455:3fa6635d04b9 but was lost in the transition to the new builder. Signed-off-by: Ian Campbell <ian.campbell@xensource.com>

| | | | | | | | | | | | It is no longer being maintained and probably shouldn't have existed in the first place, since it was almost identical to xc_linux_build.c. Signed-off-by: Hollis Blanchard <hollisb@us.ibm.com>

* | [LIBXC][POWERPC] use O_CREAT on open call for DTB_FILEJimi Xenidis2007-02-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a bug in the creating of the flat dev tree. If open is used and O_CREAT not is specified, it will fail if the file has not already been created. This patch will create the file if it does not exist already. Which will allow for DomU creation.

* | [POWERPC][XEN][LIBXC] Make xc_linux_build() use populate_physmap()Hollis Blanchard2007-03-021-25/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | - populate_physmap() is the only way to invoke guest_physmap_{add/remove}_page(), which populate our new p2m table. - To use it, we must to specify an array of PFNs where the new MFNs will be mapped. - Split out alloc_memory() from xc_linux_build(). - Fix memory free path in xc_linux_build().
