Invalidating storage, clearing entries from the buffer.

A method for clearing buffers address translation and invalidating a range of elements of a translation table storage addresses associated in a computer system, the computer system one or more central processing units in communications with a main storage comprising, having the central processing units some buffers address translation, also having the buffer address translation elements buffer address translation maintaining information address translation, with the computer system page tables and other tables address translation for translating virtual main storage addresses of a central processing unit of one or more processing units, main storage addresses in the computer system, comprising the address translation tables either l os following: one or mastablas segments, one or more segment tables and one or more tables in the first region, one or more segment tables and one or more tables in the first region and one or more tables in the second region or one or more segment tables and one or more tables of the first region and one or more tables of the second region and one or more tables of the third region where an element of a segment table comprises a source page table ; the method being characterized by comprising the steps of: extracting a multifunction instruction (600) computer of a table of Dynamic Address Translation Override (IDTE), comprising the multifunction IDTE instruction field (602) of opcode It has a value field opcode that identifies the instruction as a multi-function IDTE instruction, being the IDTE instruction multifunction to perform a first function or a second function, the first function comprising a operacionde invalidation and clearing, and the second function comprising an erase operation and not an invalidation operation; executing the IDTE instruction multifunction performing the steps of: when the function of the extracted multifunction IDTE instruction is the operation of invalidation and clearing steps 1) and 2): 1) invalidating (404) a predetermined range of one or more table element address translation, a translation table addresses, starting from a predetermined element of the address table instead; and 2) clearing (505), (508) buffers address translation elements buffers address translation associated with one or more table entries invalidated address translation; when the function of the extracted multifunction IDTE instruction consists only of an erase operation, performing the step of: deleting buffers address translation elements buffers address translation associated with one or more elements of the translation table address, comprising one or more elements of the translation table address a predetermined range of one or more elements of table address translation, a translation table addresses, starting at a predetermined location of a table element address translation.
