MISRA-C requires that shift operation cannot exceed the word length. What this patch does: - Fix the bug in 'vuart_init' The register 'dll' and 'dlh' should be uint8_t rather than char. 'dll' is

This commit changes the order of functions in arch/x86/irq.c, to make it looks cleaner, with no change within any function. Signed-off-by: Yan, Like <like.yan@...> Reviewed-by: Anthony Xu

This commit cleans up fiels of struct irq_desc: - remove irq_ prefix of irq_lock field of struct irq_desc; - remove irq_desc_state, irq_cnt and irq_lost_cnt which are not used. - change enum irq_state

There are several similar irq handlers with confusing function names and it's not friendly to call update_irq_handler() to update a proper handler after irq registration. With this commit, a single

This commit adds setup_irq()/unset_irq() to setup/unset following fields of irq_desc: irq_handler, action, action_data, flags, name, in order to make request_irq()/free_irq() cleaner. Signed-off-by:

This commit refactors the irq_desc and vector allocation/free codes, with: 1) add a global spinlock to protect the irq_desc/vector allocation; 2) three pairs of funtions are defined for

Patch [2,3,4,5/9] of v4 have been PRed. This series includes the rest patches, which: - [1/5, 2/5] refactored codes for irq request/free code clearer and easy to read; - [3/5] merged confusing irq

For this case, directly type conversion is safe and simple. BTW, we should use narrow type conversion carefully, it is dangerous in some case since it will drop high end value. BRs, Xiangyang Wu.

OK. Let me add log for now. Regards Yin, Fengwei

Sure. I will update the patch per our discussion.

Got it, can we use temporary variable "uint8_t value8 = (uint8_t) value;", so we can avoid many type conversion? BRs, Xiangyang Wu

- add handler if prepare_vm() failed; - replace assert in start_vm()/prepare_vm() with return errno; - return errno in start_vm()/reset_vm()/prepare_vm() so that caller could handle

Did you see VM_Exit with lock prefix? If not, can we add error message for now. Anthony

Sure, will go through the current code and see if there is something should be clean up.
