    intel atomisp 驱动bug

    thomas-mindray Community Member

      我在intel的E3827芯片上运行atomisp驱动时,偶发出现irq translate error,进而导致整个isp

      模块无法再重新打开,且每次open video设备都会导致内存泄露。

      日志信息如下:

      atomisp:atomisp_isr:failed to translate irq(err=1,infos=0)

      atomisp:ERROR ia_css_irq_translate failed

      atomisp  0000:00:03.0:timeout 1 of 2

      CSS Debug Info dump

      **************************

      atomisp:DFS target freq is rejected by HW

      atomisp:DFS failed

      atomisp:atomisp_reset

      atomisp:atomisp_mrfld_pre_power_down:IRQ raised!!!

      atomisp:<_atomisp_streamoff[0]

      ***************************

      atomisp 0000:00:03.0 css init failed--bad firmware?

       

      硬件平台:E3827

      操作系统:linux kernel 3.8.0+yocto project

       

      有哪位朋友知道该问题的原因?
