Selected units of storage, such as segments of storage or regions of storage, may be invalidated.
A computer implemented method for invalidating a range of two or more address translation table entries of a translation table, wherein dynamic address translation of virtual addresses to main storage address is based on translation tables, the method comprising: , wherein the range of two or more address translation table entries to be invalidated each comprise an invalid bit for invalidating, wherein when the invalid bit is 0, use of the address translation table entry for dynamic translation is permitted, wherein when the invalid bit is 1, use of the address translation table entry for dynamic translation is not permitted, the method further comprising: , wherein the computer system comprises central processors (CPUs), architected general purpose registers, address translation buffers, the address translation buffers having address translation buffer entries holding address translation information, the address translation tables consisting of any one of: one or more first region tables containing entries pointing to second region tables, the second region tables containing entries pointing to third region tables, the third region tables containing entries pointing to segment tables, the segment tables containing entries pointing to page tables;one or more second region tables containing entries pointing to third region tables, the third region tables containing entries pointing to segment tables, the segment tables containing entries pointing to page tables; and This application is a continuation of U. Yet further, in another aspect of the present invention, buffer entries associated with selected address spaces are cleared from buffers without affecting buffer entries of non-selected address spaces, and without performing invalidation.
Additional features and advantages are realized through the techniques of the present invention.
An instruction is provided to perform invalidation of an instruction specified range of segment table entries or region table entries. Other embodiments and aspects of the invention are described in detail herein and are considered a part of the claimed invention.
The instruction can be implemented by software emulation, hardware, firmware or some combination thereof.... 8,122,224 “CLEARING SELECTED STORAGE TRANSLATION BUFFER ENTRIES BASED ON TABLE ORIGIN ADDRESS” Slegel et al., filed Jan. The subject matter which is regarded as the invention is particularly pointed out and distinctly claimed in the claims at the conclusion of the specification.
System and computer program products corresponding to the above-summarized methods are also described and claimed herein.
The instruction includes, for instance, an operation code to identify an instruction to be executed; and at least one of the following: a first invalidation designation to specify information associated with a unit of storage to be invalidated, the unit of storage including a plurality of pages of storage; a second invalidation designation to specify additional information associated with the unit of storage to be invalidated; and a clearing designation to specify information associated with one of the unit of storage and another unit of storage for which one or more entries of one or more buffers are to be cleared, wherein the information specified by the clearing designation is not associated with at least one other unit of storage for which one or more entries are not to be cleared.Grace does not invalidate Free Will that, however expressed in accordance with God‘s (purposeful) designs, allows every individual to charter his or her own chosen course; that is to say, to decide whether to (freely) accept or reject what God expects from each of us or has to offer us if we willingly accept it with an open heart.As an example, if we assume that Einstein or the internet or some phenomenally intelligent being possess a mere 1% of all possible knowledge and truth – and lets say we collectively possess, oh I don't know, let's say 40% (I am being very very generous) – then there is still a vast majority of reality that could invalidate my claims (I.Nevertheless, there was always a great deal of mystery about these leaders, and no certain fact can invalidate the singular arrogance of this reply made later on by a man accused before the Court of Peers:—.Yet, if the survival of a Divine Spirit did not invalidate the death of Christ, then neither does the survival of a human spirit invalidate the death of a man in that incomplete death which prevails under the economy of redemption until the second death takes place.Instead of finding some compromise, you can have both with cache invalidation.
