It sets the undocumented bit 31 in 1281 the auxiliary control register and the FI bit in the control 1282 register, thus disabling hit-under-miss without putting the 1283 processor into full low interrupt latency mode. ARM11MPCore 1284 is not affected. 1285 | 1config ARM 2 bool 3 default y 4 select HAVE_AOUT 5 select HAVE_DMA_API_DEBUG 6 select HAVE_IDE 7 select HAVE_MEMBLOCK 8 select RTC_LIB --- 1269 unchanged lines hidden (view full) --- 1278 This options enables the workaround for the 364296 ARM1136 1279 r0p2 erratum (possible cache data corruption with 1280 hit-under-miss enabled).

Under certain timing circumstances, a data 1293 cache line maintenance operation by MVA targeting an Inner 1294 Shareable memory region may fail to proceed up to either the 1295 Point of Coherency or to the Point of Unification of the 1296 system. This workaround adds a DSB instruction before the 1297 relevant cache maintenance functions and sets a specific bit 1298 in the diagnostic control register of the SCU. 1299 | |
