please update the rknpu version to 0.98

[kiron111]

if the rknpu version is old, all the new rkllm model will not worked
pls update it, thankyou

the rknpu 0.9.8 driver is here
https://github.com/airockchip/rknn-llm/tree/main/rknpu-driver

and pls refer to the offical doc
https://github.com/airockchip/rknn-llm/tree/main/doc
quote from the offiical doc:

补充说明： 若是发现编译内核的过程中，出现如图 2-1 的错误日志： 图 2-1 内核编译错误 用户需要修改内核头文件 kernel/include/linux/mm.h，加入以下代码：
static inline void vm_flags_set(struct vm_area_struct *vma, vm_flags_t flags)
{ vma->vm_flags |= flags; }
static inline void vm_flags_clear(struct vm_area_struct *vma, vm_flags_t flags)
{ vma->vm_flags &= ~flags; }

I agree, currently the rknpu driver is 0.9.8, while the driver here is not updated yet.

[LuckyMouseLai]

i agree, 0.9.8 is needed.

编译rknpu 0.9.6 可以正常通过
rknpu 0.9.8 遇到 如下错误，不知道如何解决

问题解决了，参考 https://blog.csdn.net/weixin_74253011/article/details/141058714
rknpu_devfreq.c:
static const struct rockchip_opp_data rk3576_npu_opp_data = {
.set_read_margin = rk3576_npu_set_read_margin,
// .set_soc_info = rockchip_opp_set_low_length, 未定义, 需要删除
#if KERNEL_VERSION(6, 1, 0) <= LINUX_VERSION_CODE
.config_regulators = npu_opp_config_regulators,
.config_clks = npu_opp_config_clks,
#endif
};

更新后查看板子上的/sys/kernel/debug/rknpu/version
显示 RKNPU driver: v0.9.8
