If I work with embedded system where I know all my tasks running and there is not a user how could I do it? What I tried is create the kernel thread in my init_module using: #include <linux/kthread.h> struct task_struct *kthread_create(int (*threadfn)(void *data), void *data, const char namefmt[], ...) and then running it with: #include <linux/sched.h> extern int wake_up_process(struct task_struct *tsk); These functions stars a Kthread which has a NON RT priority. I can see this using the ps command from user space. Because it's not a real time thread is why I want, better need, to change its priority, to have only real time threads running in my driver. I want to use the Kthread as a bottom half for the interrupts. How could I create real time kernel threads then? is kthread_create wrong for real time enviroment? -- __________________________________________________________________________________ Mónica Puig-Pey González E-mail: puigpeym@unican.es Grupo de Computadores y Tiempo Real, Departamento de Electrónica y Computadores.

That's what they are made for. I just started using threaded interrupt handlers in 2.6.39 for an arm system (pcm043 - arm1136jfs). The results where not so good as i expected. I set the rt prio of the interrupt to 99 (the scheduling type made difference since it was the only interrupt at this level). The user io driver for this where set to 98. I hadn't instrumented the irqthread but the latencies where to high for our buffer which can hold data for about 400µs. After configuring the IRQ as non-threaded, but still using threaded irqs the latencies where fast enough for the mentioned buffer size. Nevertheless are there still scheduling latencies for the usermode handler thread which then runs at rt prio 99 for about 1ms. I know this is not an preempt-rt kernel but i hoped to get better values out of this configuration. So if anybody has an idea how to get better latencies out of a 2.6.39 kernel, please let me know. I triead SLAB and SLOB allocator and they didn't made any difference for me. Best regards Tim PS: i patched the kernel to get threadedirqs with: diff --git a/arch/arm/mach-mx3/Kconfig b/arch/arm/mach-mx3/Kconfig index 4e05237..28ae32c 100644 --- a/arch/arm/mach-mx3/Kconfig +++ b/arch/arm/mach-mx3/Kconfig @@ -162,6 +162,7 @@ config MACH_PCM043 select IMX_HAVE_PLATFORM_SDHCI_ESDHC_IMX select IMX_HAVE_PLATFORM_SPI_IMX select MXC_ULPI if USB_ULPI + select IRQ_FORCED_THREADING help Include support for Phytec pcm043 platform.

The mainline forced irq thread handling is no guarantee for lower latencies. We need to disable preemption via local_bh_disable() for the forced threaded interrupts to satisfy the handler vs. softirq assumptions. So you might get long lasting preempt disabled regions due to long running interrupt handlers. Aside of that you still can get long periods due to code which runs with preemption or interrupts disabled. The forced threaded option has no way to change that. It would be interesting to find the root cause for those >1ms latencies. Tracing is your friend. Thanks, tglx ^ permalink raw reply [flat|nested] 4+ messages in thread
