A TLBI from EL2 impacting EL1 involves messing with the EL1&0 translation regime, and the page table walker may still be performing speculative walks. Piggyback on the existing DSBs to always have a DSB ISH that will synchronise all load/store operations that the PTW may still have. Web17 jul. 2013 · Kernel startup entry point. ----- This is normally called from the decompressor code. The requirements are: MMU = off, D-cache = off, I-cache = dont care, r0 = 0, r1 = machine nr, r2 = atags or dtb pointer. This code is mostly position independent, so if you link the kernel at 0xc0008000, you call this at __pa(0xc0008000).

WebThe VHE code is largely unaffected, thanks to the DSB in the context switch. The last patch isn't directly related, but a superfluous ISB was spotted while working on this series. - From v2 [2] - Give an option to the nVHE TLBI code to still issue non-shareable DSBs, as there are pending patches making use of it. Web17 mrt. 2024 · TDA4VM: A question about C7x cache. I am currently working on a task whose main purpose is to add a memory area on the DDR for use by C66 and C7x. I know that we can use the cache invalidation function to avoid cache consistency issues. But we use this memory frequently, I think calling this function frequently may be time-consuming.

WebBut STM has not integrated such a CCI (so complex for a small MCU, CM4/CM7 system). So, the sharable attribute (S-bit) does not have any function or meaning. 'is equivalent' means here for my understanding: 'if you have shareable memory, e.g. shared between MCU and DMA - you had to run/configure as non-cacheable.
