Previously, IRQ bounds checking (irq >= 0 && irq < NR_IRQS) was duplicated
across multiple IRQ subsystem functions before calling IRQ_TO_NDX(). This
led to code duplication and inconsistency.
This patch consolidates all IRQ bounds checking into the IRQ_TO_NDX() macro
itself, which now returns -EINVAL for out-of-bounds IRQ numbers. This approach:
1. Eliminates duplicated bounds checking code
2. Ensures consistent error handling across all IRQ functions
3. Simplifies caller code - just check if IRQ_TO_NDX() returns negative
4. Makes the macro behavior more predictable and self-contained
Changes:
- Modified IRQ_TO_NDX() to check (irq < 0 || irq >= NR_IRQS) and return -EINVAL
- Removed redundant IRQ range checks in irq_attach(), irq_attach_thread(),
irq_attach_wqueue(), and irqchain_detach()
- Simplified error handling to check ndx < 0 after IRQ_TO_NDX() call
This consolidation reduces code size and improves maintainability while
preserving all existing error checking functionality.

IRQ_TO_NDX() returns int (can be negative on error), but was assigned
to unsigned int variable 'ndx', violating MISRA C-2012 Rule 10.3.
This also improves the condition check: instead of checking 'irq >= 0 && irq < NR_IRQS',
we now check 'ndx >= 0' which properly handles the error case where IRQ_TO_NDX()
returns a negative error code.
Changes:
- Change 'ndx' type from unsigned int to int
- Simplify condition from 'irq >= 0 && irq < NR_IRQS' to 'ndx >= 0'
This ensures type correctness and proper error handling.

Add support for running the OS in tickless mode with hrtimer, allowing
the scheduler to operate without periodic ticks while maintaining
high-resolution timer functionality.
Signed-off-by: Chengdong Wang <wangchengdong@lixiang.com>
The hrtimer subsystem is independent of the OS tick mechanism and tickless
mode. It must always be able to reprogram the hardware timer to achieve
nanosecond-level resolution.
A recent update restricted hardware timer reprogramming to tickless mode
only. As a result, hrtimer no longer functions correctly when the scheduler
is running in tick-based mode.
This change removes the incorrect dependency on tickless mode and restores
proper hrtimer operation.
