Subject: [PATCH 0 of 2] Add libxc API that sets mem_access type for an array of gfns
Date: Thu, 26 Apr 2012 11:33:29 -0700 [thread overview]
Message-ID: <patchbomb.1335465209@vollum> (raw)
When the mem_access type needs to be changed for multiple discontiguous gfns, calling xc_hvm_set_mem_access() multiple times does not perform very well. The main pain points are the multiple libxc calls themselves plus the multiple map_domain_page() / unmap_domain_page() and ept_sync_domain() calls for each ept_set_entry(gfn). The following patches adds a new mem_access API that sets the mem_access type for an array of guest physical addresses in one libxc call with minimal map_domain_page() / unmap_domain_page() and ept_sync_domain() calls.
