[ros-diffs] [ion] 24908: - Fix prototype/definition of HalCalibratePerformanceCounter and properly implement it. - Implement KeStallExecutionProcessor in its own assembly file isntead of using inlined GCC assembly, and align the loop to 16 bytes for more streamlined execution speed. - Mask out clock interrupt during Phase 0 and Initialize clock interrupt on HAL Phase 1. This enables the HAL clock interrupt which was already written. - Make the clock interrupt use HalpCurrentTimeIncrement instead of hardcoding a value. - Re-implement HalpInitializeClock to allow for dynamic increments from 1ms to 15ms with appropriate rollovers and to call KeSetTimeIncrement to update timer values with the kernel. - Implement HalSetTimeIncrement to allow changing the clock ms increment (but this isn't yet respected). - Remove system/runtime update routines from the deprecated IRQ implementation and use the newer assembly ones already written, since we're now using the HAL clock interrupt. Remove other unused code. - Fix more bugs in new hal IRQ implementation (that still isn't used yet due to regressions) and implement HalClearSoftwareInterrupt.

Log:
- Fix prototype/definition of HalCalibratePerformanceCounter and properly implement it.
- Implement KeStallExecutionProcessor in its own assembly file isntead of using inlined GCC assembly, and align the loop to 16 bytes for more streamlined execution speed.
- Mask out clock interrupt during Phase 0 and Initialize clock interrupt on HAL Phase 1. This enables the HAL clock interrupt which was already written.
- Make the clock interrupt use HalpCurrentTimeIncrement instead of hardcoding a value.
- Re-implement HalpInitializeClock to allow for dynamic increments from 1ms to 15ms with appropriate rollovers and to call KeSetTimeIncrement to update timer values with the kernel.
- Implement HalSetTimeIncrement to allow changing the clock ms increment (but this isn't yet respected).
- Remove system/runtime update routines from the deprecated IRQ implementation and use the newer assembly ones already written, since we're now using the HAL clock interrupt. Remove other unused code.
- Fix more bugs in new hal IRQ implementation (that still isn't used yet due to regressions) and implement HalClearSoftwareInterrupt.

- * NOTE: This function MUST NOT be optimized by the compiler!
- * If it is, it obviously will not delay AT ALL, and the system
- * will appear completely frozen at boot since
- * HalpCalibrateStallExecution will never return.
- * There are three options to stop optimization:
- * 1. Use a volatile automatic variable. Making it delay quite a bit
- * due to memory accesses, and keeping the code portable. However,
- * as this involves memory access it depends on both the CPU cache,
- * e.g. if the stack used is already in a cache line or not, and
- * whether or not we're MP. If MP, another CPU could (probably would)
- * also access RAM at the same time - making the delay imprecise.
- * 2. Use compiler-specific #pragma's to disable optimization.
- * 3. Use inline assembly, making it equally unportable as #2.
- * For supported compilers we use inline assembler. For the others,
- * portable plain C.
