Update dfs_cromfs.c
|
|
Do unmap before shrink so we don't see mapped entry on page table
insertion, which is not acceptable for riscv implementation of
architecture porting.
Changes:
- add un-mapping of pte on `_null_shrink()`

[dfs] feat: Mark dirty on unmap for shared mapping
This patch optimizes the pcache varea management by refining the
conditions under which pages are marked dirty, specifically targeting
the unmap operations in the dfs_pcache component. These changes were
necessary to enhance the efficiency of page cache management.
Changes:
- Adjusted include statements in `dfs_pcache.c` for better organization.
- Modified `dfs_aspace_unmap` function:
- Added a check to ensure `varea` is not privately locked before marking a page as dirty.
- Updated `dfs_aspace_page_unmap` function:
- Added a similar check for `varea` lock status before marking a page as dirty.

Add VDSO functionality under the aarch64 architecture
|
|
The changes unify the tick.c implementations for all risc-v64
architectures, leveraging the CPUTIME feature. This refactoring was
necessary to streamline the codebase, and ensure consistent timer
handling across different platforms.
Changes:
- Updated `Kconfig` in `bsp/cvitek/cv18xx_risc-v` to fix formatting issues.
- Updated .config for BSPs to update `CPUTIME_TIMER_FREQ`
- Updated header of for API `riscv_cputime_init`
- Initialized riscv timer on `rt_hw_tick_init`
- Refactored `tick.c` and `tick.h` in `libcpu/risc-v/t-head/c906` and `libcpu/risc-v/virt64`:
- Replaced direct use of `rdtime` with `clock_cpu_gettime`.
- Removed redundant timer frequency definitions.
- Added static assertions to check the value of `CPUTIME_TIMER_FREQ`.
- Initialized `tick_cycles` based on `CPUTIME_TIMER_FREQ`.
- Integrated `ktime` support for tick initialization.

feat: [libcpu/c906] support ARCH_REMAP_KERNEL
This change was necessary to enable the remapping of the kernel image to
a high virtual address region on the c906 platform.
Changes:
- Introduced new configuration options `ARCH_REMAP_KERNEL`, and
`ARCH_USING_ASID` under the `ARCH_RISCV64` section.
- Updated MMU initialization and switching functions to incorporate
remapping handling.
- Modified page table setup for proper memory attribute settings.
- Added support for early memory setup, kernel remapping
- Added conditional compilation for ASID support in the `rt_aspace` struct,
since this is not enable currently for most architecture.

Skip configure on open since all configs are copied from the current
configuration on device. So we don't bother to set it back to device
again.

* [libcpu] support for ARCH_REMAP_KERNEL
These changes introduce support for the ARCH_REMAP_KERNEL configuration,
which isolates kernel space in high virtual address regions. This feature
is necessary to enhance memory protection and management by segregating
user and kernel spaces more effectively.
Changes:
- Updated conditional macros to check for ARCH_REMAP_KERNEL instead of
ARCH_KERNEL_IN_HIGH_VA in board initialization files to reflect the new
configuration option.
- Modified qemu-virt64-riscv Kconfig and SConstruct files to include and
utilize ARCH_REMAP_KERNEL.
- Created a new linker script `link_smart.lds` for smart linking in qemu-virt64-riscv.
- Updated rtconfig.py to use a more flexible execution path setup.
- Enhanced user address space definitions in `lwp_arch.h` to support the
new virtual address mappings.
- Adjusted kernel memory initialization and mapping logic in `c906/mmu.c`
and `virt64/mmu.c` to account for high virtual address regions.
- Added Kconfig option to enable ARCH_REMAP_KERNEL for RISCV64 architectures.
- Enhanced memory setup functions to support new mapping scheme, including
updates to early page table setup and address relocation logic.
These modifications ensure that the system can utilize high memory
addresses for the kernel, improving memory isolation and system stability.

* [utest] remove delay for on thread testing
The delay is introduced from 0dc7b9a5a26030a945723569c64f5be46bd70ae1.
Though this is unnecessary for on sync utest.
So this is removed by a new entry and delay for asynchronous utest only.
