This patch cleans up some 80-odd warnings I was seeing when compiling the xenpci driver, all completely trivial. It also replaces the use of asm for calling cpuid with the __cpuid compiler intrinsic, and modifies calling code accordingly. I''m pretty sure my mailer going to mangle the inline patch (below) so I''m attaching the pristine version. (will try to fix for next time) --

Please CC as I''m not subscribed to valgrind-developers. Under Xen the toolstack is responsible for managing the domains in the system, e.g. creating, destroying, and otherwise manipulating them. To do this it uses a number of ioctls on the /proc/xen/privcmd device. Most of these (the MMAPBATCH ones) simply set things up such that a subsequenct mmap call will map the desired guest

Keir, Ian, With PCI mmconfig option on, and with the PCI express enabled BIOS, the dom0 kernel reads the PCI config from fix-mapped PCI mmconfig space. The PCI mmconfig space is of 256MB size, and it''s access is implemented differently on i386 & x86_64. On x86_64 the whole 256MB is mapped in the Kernel virtual address space. On i386 it will consume too much of the kernels

Is this PAE or non-PAE? Please can you try forceing emulation mode by toggling the "#if 0" in arch/x86/mm.c ptwr_do_page_fault The other thing to try is modifying set_pte_pfn_ma to call xen_l1_update rather than set_pte. You could try set_pte_at too. This will help narrow down the issue. Thanks, Ian > Keir, Ian, > With PCI mmconfig option on, and with the PCI express >

This patch implements persistent grants for the xen-blk{front,back} mechanism. The effect of this change is to reduce the number of unmap operations performed, since they cause a (costly) TLB shootdown. This allows the I/O performance to scale better when a large number of VMs are performing I/O. Previously, the blkfront driver was supplied a bvec[] from the request queue. This was granted to
