Lines Matching full:present

9  * A MMU present SPTE is backed by actual memory and may or may not be present
10  * in hardware.  E.g. MMIO SPTEs are not considered present.  Use bit 11, as it
12  * better code than for a high bit, e.g. 56+.  MMU present checks are pervasive
61  * as not-present for access tracking purposes. We do not save the W bit as the
128  * MMU-present bit.  The generation obviously co-exists with the magic MMIO
129  * mask/value, and MMIO SPTEs are considered !MMU-present.
131  * The SPTE MMIO mask is allowed to use hardware "present" bits (i.e. all EPT
174  * This mask must be set on all non-zero Non-Present or Reserved SPTEs in order
187  * non-present intermediate value. Other threads which encounter this value
190  * Use a semi-arbitrary value that doesn't set RWX bits, i.e. is not-present on
198 /* Removed SPTEs must not be misconstrued as shadow present PTEs. */
213  * In some cases, we need to preserve the GFN of a non-present or reserved
346  * A shadow-present leaf SPTE may be non-writable for 4 possible reasons:
407  * The Host-writable bit is not modified on present SPTEs, it is only set or
408  * cleared when an SPTE is first faulted in from non-present and then remains
416 /* Note: spte must be a shadow-present leaf SPTE. */
