Thanks Javier for quick response.
But i have a valid LFID and uploaded valid id_rsa.pub key to gerrit "SSH Public Key" section. Then i thought of ping the ssh server: ssh -p 29418 <my LFID>@gerrit.zephyrproject.org Agent admitted failure to sign using the key. Permission denied (publickey). I am developing inside virtual box, if that is causing any problem?

RFC: draft x86 interrupt documentation
Boie, Andrew P
I had a recent need to explain in detail the x86 IRQ implementation to
some colleagues working on Quark CPUs, and wrote this document. Eventually I would like to clean this up, discuss other arches, and make it part of the official Zephyr documentation. Comments appreciated. ##### 1. APIs Overview of the interrupt API in Zephyr can be found here: https://nexus.zephyrproject.org/content/sites/site/org.zephyrproject.zephyr/latest/kernel/nanokernel/nanokernel_interrupts.html Note that Zephyr currently only officially supports static registration of interrupts at build time. We used to also support dynamic IRQs which are wired at runtime, but this has been deprecated. The code for irq_connect_dynamic() still exists in the codebase but will not be discussed here. This document assumes you are familiar with the x86 IDT. We will mostly discuss interrupts, exception handling is briefly described at the end of this document. 2. High-level design As seen in the API definitions, ISR routines in Zephyr take the following form: void isr(void *parameter); And are registered with the IRQ_CONNECT() macro: /** * Configure a static interrupt. * * All arguments must be computable by the compiler at build time; if this * can't be done use irq_connect_dynamic() instead. * * @param irq_p IRQ line number * @param priority_p Interrupt priority * @param isr_p Interrupt service routine * @param isr_param_p ISR parameter * @param flags_p Arch-specific IRQ configuration flags * * @return The vector assigned to this interrupt */ #define IRQ_CONNECT(irq_p, priority_p, isr_p, isr_param_p, flags_p) \ _ARCH_IRQ_CONNECT(irq_p, priority_p, isr_p, isr_param_p, flags_p) On x86, there's no place to put the parameter in the IDT, all you can assign to a vector is a void isr(void). In Zephyr, what actually gets installed in the IDT is an automatically generated assembly stub. For IAMCU ABI it looks like this: /* Push caller-saved registers onto the stack */ pushl %eax pushl %edx pushl %ecx /* Put hard-coded ISR and ISR parameter into function args, * with IAMCU these go in regs and not the stack */ movl <isr routine>, %eax movl <isr parameter>, %edx /* Call common interrupt handling code */ call _execute_handler /* Restore caller-saved registers popl %ecx popl %edx popl %eax /* Return to the interrupted context */ iret Note that the implementation of this is very different for Sys V ABI, but the policy is the same. For purposes of this document we'll just describe the IAMCU implementation. We'll discuss what _execute_handler does in more detail later, and how these stubs are created. First, let's talk about how we create the IDT and populate it with these stubs. ###### 3. ISR_LIST Each invocation of IRQ_CONNECT() populates an array called the ISR_LIST, placed in a special binary section called ".intList". The build tool gen_idt (described in more detail later) uses ISR_LIST to create a binary IDT image. Each element of the ISR_LIST contains all the information needed to generate the IDT entry and looks like this: typedef struct s_isrList { /** Address of ISR/stub */ void *fnc; /** IRQ associated with the ISR/stub */ unsigned int irq; /** Priority associated with the IRQ */ unsigned int priority; /** Vector number associated with ISR/stub */ unsigned int vec; /** Privilege level associated with ISR/stub */ unsigned int dpl; } ISR_LIST; Not all the members of this struct need to populated with specific values. Use-cases as follows: * For APIC, the typical case for an interrupt is to set the priority and irq fields, and set vec to -1. This means gen_idt will automatically select a free vector based on the supplied priority level, with each priority level corresponding to a group of 16 vectors. Priority 0 corresponding to vectors 32-47, and so forth. This makes it easy for users, as they don't have to set a specific vector ID. Instead the vector will be of some range determined by the priority level instead. * For MVIC, there is a fixed relationship between IRQ lines and vectors. The priority field is set to -1 and the vector is set to irq + 0x20. * For CPU exceptions, the priority and irq fields are set to -1 and the specific vector to use is provided. The handler function will simply get put at the requested vector. CPU exceptions configured with different macros than IRQ_CONNECT() and have different handling in the OS, briefly described later in this document. * Currently dpl is always zero. We don't support other DPLs at the moment, gen_idt will throw an error if it finds something other than zero here. At the end of the build, but before the final link, we now have an INT_LIST array which reflects the intended configuration for the IDT. Before Zephyr is actually linked, the gen_idt tool runs and generates an object file containing the IDT binary, which gets linked into the final executable. ###### 4. gen_idt The code for gen_idt is located in scripts/gen_idt. Broadly speaking it consumes the ISR_LIST, validates the sanity of its contents, and creates an object file creating the IDT and a few other data structures. For each entry in ISR_LIST, gen_idt creates a present 32-bit i386 Interrupt gate for it with DPL 0. In addition to creating the IDT, gen_idt populates a few other data structures. * For APIC, _irq_to_interrupt_vector array contains the mapping between irq lines and the vectors assigned to them by gen_idt. We need this at runtime so that we can program the APIC at boot: extern unsigned char _irq_to_interrupt_vector[]; #define _IRQ_TO_INTERRUPT_VECTOR(irq) \ ((unsigned int) _irq_to_interrupt_vector[irq]) For MVIC, whose mapping is fixed, this array isn't generated and the macro is instead: #define _IRQ_TO_INTERRUPT_VECTOR(irq) (irq + 0x20) * _interrupt_vectors_allocated is a bitfield indicating which entries in the IDT are in use. It is only used by the deprecated dynamic IRQ implementation (so that it can quickly find free vectors) and will eventually disappear. gen_idt is run at the end of the build just before the final linking step. ####### 5. IRQ_CONNECT() The IRQ_CONNECT() macro is a complicated beast with build and runtime components. It does the following: 1. Declare an assembly language ISR stub, which calls common interrupt entry/cleanup code and calls the user-supplied ISR with parameter. The address of this stub is what gets put in the IDT. 2. Declare appropriate ISR_LIST entry to be put in .isrList section, for gen_idt to use to create the actual IDT. 3. Perform any runtime initialization. For APIC, this establishes the irq line to vector mapping, and set triggering options. Depending on the irq line this will be accomplished by poking either LOAPIC or IOAPIC registers. For MVIC we just set triggering options. This stuff is all found in include/arch/x86/arch.h. There are detailed comments, I've omitted them since I'm just going to re-explain everything. First, the _ARCH_IRQ_CONNECT macro itself: /* * @param irq_p IRQ line number * @param priority_p Interrupt priority * @param isr_p Interrupt service routine * @param isr_param_p ISR parameter * @param flags_p IRQ triggering options * * @return The vector assigned to this interrupt */ #define _ARCH_IRQ_CONNECT(irq_p, priority_p, isr_p, isr_param_p, flags_p) \ ({ \ __asm__ __volatile__( \ "jmp 2f\n\t" \ ".pushsection .intList\n\t" \ ".long 1f\n\t" /* ISR_LIST.fnc */ \ ".long %P[irq]\n\t" /* ISR_LIST.irq */ \ ".long %P[priority]\n\t" /* ISR_LIST.priority */\ ".long %P[vector]\n\t" /* ISR_LIST.vec */ \ ".long 0\n\t" /* ISR_LIST.dpl */ \ ".popsection\n\t" \ "1:\n\t" \ _IRQ_STUB_ASM \ "2:\n\t" \ : \ : [isr] "i" (isr_p), \ [isr_param] "i" (isr_param_p), \ [priority] "i" _PRIORITY_ARG(irq_p, priority_p), \ [vector] "i" _VECTOR_ARG(irq_p), \ [irq] "i" (irq_p)); \ _SysIntVecProgram(_IRQ_TO_INTERRUPT_VECTOR(irq_p), (irq_p), (flags_p)); \ _IRQ_TO_INTERRUPT_VECTOR(irq_p); \ }) First we see a complex inline assembly. This does two things: 1. It creates the assembly language stub. The details of this are in _IRQ_STUB_ASM. This takes two forms depending on whether we are using Sys V or IAMCU ABI. Here's the IAMCU template: #define _IRQ_STUB_ASM \ "pushl %%eax\n\t" \ "pushl %%edx\n\t" \ "pushl %%ecx\n\t" \ "movl %[isr], %%eax\n\t" \ "movl %[isr_param], %%edx\n\t" \ "call _execute_handler\n\t" \ "popl %%ecx\n\t" \ "popl %%edx\n\t" \ "popl %%eax\n\t" \ "iret\n\t" You'll notice at the top of the main __asm__ statement is a 'jmp 2f'. In assembly syntax '2f' refers to the first subsequent occurrence of the non-unique label 2, which is immediately after the stub declaration. This prevents the generated stub from actually being executed in the context of the IRQ_CONNECT() call, execution just jumps immediately after it. 2. An entry in INT_LIST is declared. The .fnc member is populated with '.long 1f' which is the memory address of the stub, since the next '1' label is immediately before it. We use pushsection/popsection to ensure that this INT_LIST entry goes in the desired ".intList" section. After the assembly stub is a runtime call to _SysIntVecProgram to tell the interrupt controller what the irq -> vector mapping is, and the triggering flags. This is where the _irq_to_interrupt_vector array gets used, see the _IRQ_TO_INTERRUPT_VECTOR call. Finally there is another instance of _IRQ_TO_INTERRUPT_VECTOR to serve as the return value for this macro; the macro is a GCC compound expression ({ }) so whatever expression is last is the value "returned". In practice this is rarely needed. ##### 6. _execute_handler The code for this is in arch/x86/core/iamcu_abi/intstub.c. It takes the ISR and ISR parameter as parameters. When this is called, the assembly stub has already taken care of saving the thread's caller-saved registers onto the stack: void _execute_handler(int_handler_t function, int context); This function does the following: 1. If we are not already on the IRQ stack (such as with nested IRQs), switch to the IRQ stack. The old thread stack pointer is pushed onto the IRQ stack so we can get back to it. 2. If nested interrupts are enabled in the kernel configuration, re-enable interrupts. 3. The handler function is called with the supplied context as its parameter. 4. Disable interrupts again if we had re-enabled them in step 3. 5. EOI is performed by poking the LOAPIC. LMT CPUs have a bug where this is not propagated correctly to the IOAPIC, there is some workaround code for this situation to also poke the IOAPIC. 6. If we are not in a nested interrupt, switch back to he thread stack. The kernel now decides whether a scheduling decision is needed. If the interrupted context was a preemptible thread and there are any pending fibers, _Swap is called. This will push the callee-saved registers onto the stack and do a context switch. 7. Control goes back to the stub, which restores caller-saved registers that were pushed onto the stack and returns control to the interrupted context with 'iret'. If a context switch was performed, this might not be the same context we were in when the interrupt happened. For Sys V ABI, both the generated stubs and the common interrupt handling code are completely different, but the policy is exactly the same. ##### 7. Exceptions Exceptions are not configured with IRQ_CONNECT. Handlers for exceptions are set up in arch/x86/core/excstub.S with the EXC_HANDLER() and EXC_HANDLER_CODE() macros, depending on whether the particular exception pushes an error code onto the stack or not. These boil down to the NANO_CPU_EXC_CONNECT() macro which also registers an entry into the INT_LIST and creates an assembly stub. Unlike interrupts, exceptions do not have any user parameters (except for some cases where the CPU pushes an error code), the exception is processed without switching stacks, and there are no scheduling decisions at the end. -- Andrew Boie Staff Engineer - EOS Zephyr Intel Open Source Technology Center

Re: zephyr cc2520

Hi David,
On Wed, 2016-05-11 at 16:54 +0800, David.Dai(a)alitech.com wrote: Hi sir,Try to activate some debugging in the cc2520 driver first. Set CONFIG_TI_CC2520_DEBUG=y in your projects conf file. If that shows that network packets are not sent, then you can start to activate debugging options in the lower MAC stack and IP stack. See various IP stack debugging options in net/ip/Kconfig.debug file for details. Cheers, Jukka

zephyr cc2520
david.dai@...
Hi sir,
I am porting cc2520 driver to arduino_due board, when sending udp packet over cc2520. the packet is never transmitted by cc2520 driver. I don't know if cc2520 driver has run correctly on any zephyr platform? to debug, where should I focus on, cc2520 driver or zephyr ip stack? Thank you!

Re: [PATCH 2/4] nanokernel: Introduce workqueue API
Benjamin Walsh <benjamin.walsh@...>
On Mon, May 9, 2016 at 6:31 PM, Benjamin WalshI'll wait for your implementation before commenting more, but yes, the only thing that I saw was similar between the two was that the fiber could be shared, and of course, that means that both the work queue and the callout systems schedule work by adding it to the fifo the fiber is waiting on.
