When completed with all of the PMD (L2) entries, and all of them have - * been set to RO, make sure to set RO the PUD (L3). Do the same - * operation on PGD (L4) pagetable entries that have a PUD (L3) entry. - * 5). Now before you can use those pages (so setting the cr3), you MUST also - * pin them so that the hypervisor can verify the entries. This is done - * via the HYPERVISOR_mmuext_op(MMUEXT_PIN_L4_TABLE, guest physical frame - * number of the PGD (L4)). And this point the HYPERVISOR_mmuext_op( - * MMUEXT_NEW_BASEPTR, guest physical frame number of the PGD (L4)) can be - * issued. - * For 32-bit guests, the L4 is not used (as there is less pagetables), so - * instead use L3. - * At this point the pagetables can be modified using the MMU_NORMAL_PT_UPDATE - * hypercall. Also if so desired the OS can also try to write to the PTE - * and be trapped by the hypervisor (as the PTE entry is RO). - * - * To deallocate the pages, the operations are the reverse of the steps - * mentioned above. The argument is MMUEXT_UNPIN_TABLE for all levels and the - * pagetable MUST not be in use (meaning that the cr3 is not set to it). - * - * ptr[1:0] == MMU_MACHPHYS_UPDATE: - * Updates an entry in the machine->pseudo-physical mapping table. - * ptr[:2] -- Machine address within the frame whose mapping to modify. - * The frame must belong to the FD, if one is specified. - * val -- Value to write into the mapping entry. - * - * ptr[1:0] == MMU_PT_UPDATE_PRESERVE_AD: - * As MMU_NORMAL_PT_UPDATE above, but A/D bits currently in the PTE are ORed - * with those in @val. - * - * @val is usually the machine frame number along with some attributes. - * The attributes by default follow the architecture defined bits. Meaning that - * if this is a X86_64 machine and four page table layout is used, the layout - * of val is: - * - 63 if set means No execute (NX) - * - 46-13 the machine frame number - * - 12 available for guest - * - 11 available for guest - * - 10 available for guest - * - 9 available for guest - * - 8 global - * - 7 PAT (PSE is disabled, must use hypercall to make 4MB or 2MB pages) - * - 6 dirty - * - 5 accessed - * - 4 page cached disabled - * - 3 page write through - * - 2 userspace accessible - * - 1 writeable - * - 0 present - * - * The one bits that does not fit with the default layout is the PAGE_PSE - * also called PAGE_PAT). The MMUEXT_[UN]MARK_SUPER arguments to the - * HYPERVISOR_mmuext_op serve as mechanism to set a pagetable to be 4MB - * (or 2MB) instead of using the PAGE_PSE bit. - * - * The reason that the PAGE_PSE (bit 7) is not being utilized is due to Xen - * using it as the Page Attribute Table (PAT) bit - for details on it please - * refer to Intel SDM 10.12. The PAT allows to set the caching attributes of - * pages instead of using MTRRs. - * - * The PAT MSR is as follows (it is a 64-bit value, each entry is 8 bits): - * PAT4 PAT0 - * +-----+-----+----+----+----+-----+----+----+ - * | UC | UC- | WC | WB | UC | UC- | WC | WB | <= Linux - * +-----+-----+----+----+----+-----+----+----+ - * | UC | UC- | WT | WB | UC | UC- | WT | WB | <= BIOS (default when machine boots) - * +-----+-----+----+----+----+-----+----+----+ - * | rsv | rsv | WP | WC | UC | UC- | WT | WB | <= Xen - * +-----+-----+----+----+----+-----+----+----+ - * - * The lookup of this index table translates to looking up - * Bit 7, Bit 4, and Bit 3 of val entry: - * - * PAT/PSE (bit 7) ... PCD (bit 4) .. PWT (bit 3). - * - * If all bits are off, then we are using PAT0. If bit 3 turned on, - * then we are using PAT1, if bit 3 and bit 4, then PAT2.. - * - * As you can see, the Linux PAT1 translates to PAT4 under Xen. Which means - * that if a guest that follows Linux's PAT setup and would like to set Write - * Combined on pages it MUST use PAT4 entry. Meaning that Bit 7 (PAGE_PAT) is - * set. For example, under Linux it only uses PAT0, PAT1, and PAT2 for the - * caching as: - * - * WB = none (so PAT0) - * WC = PWT (bit 3 on) - * UC = PWT | PCD (bit 3 and 4 are on). - * - * To make it work with Xen, it needs to translate the WC bit as so: - * - * PWT (so bit 3 on) --> PAT (so bit 7 is on) and clear bit 3 - * - * And to translate back it would: - * - * PAT (bit 7 on) --> PWT (bit 3 on) and clear bit 7. - */ -#define MMU_NORMAL_PT_UPDATE 0 /* checked '*ptr = val'. ptr is MA. */ -#define MMU_MACHPHYS_UPDATE 1 /* ptr = MA of frame to modify entry for */ -#define MMU_PT_UPDATE_PRESERVE_AD 2 /* atomically: *ptr = val | (*ptr&(A|D)) */ - -/* - * MMU EXTENDED OPERATIONS - * - * ` enum neg_errnoval - * ` HYPERVISOR_mmuext_op(mmuext_op_t uops[], - * ` unsigned int count, - * ` unsigned int *pdone, - * ` unsigned int foreigndom) - */ -/* HYPERVISOR_mmuext_op() accepts a list of mmuext_op structures. - * A foreigndom (FD) can be specified (or DOMID_SELF for none). - * Where the FD has some effect, it is described below. - * - * cmd: MMUEXT_(UN)PIN_*_TABLE - * mfn: Machine frame number to be (un)pinned as a p.t. page. - * The frame must belong to the FD, if one is specified. - * - * cmd: MMUEXT_NEW_BASEPTR - * mfn: Machine frame number of new page-table base to install in MMU. - * - * cmd: MMUEXT_NEW_USER_BASEPTR [x86/64 only] - * mfn: Machine frame number of new page-table base to install in MMU - * when in user space. - * - * cmd: MMUEXT_TLB_FLUSH_LOCAL - * No additional arguments.
