Why QEMU translates one instruction to a TB??

Hi all, We try to add DSP architecure to QEMU 4.2. To load the COFF format object file, we have added loader code to load content from the object file. The rom_add_blob() function is used. We firstly analyze the COFF file to figure out which sections are chained together(so each chain

Why QEMU treats each instruction as one translation block?

Re: Implement standard file operation with QEMU

Hello Phil, What I want to realize is to be able to call standard file operations (open, read, write etc) in the application program, and execute such programs in QEMU. But I am building under system mode. TI provide copilation toolchain and a library that provide partial functionality from

Implement standard file operation with QEMU

Hi all, I am trying to implment standard file operation (stdio) with QEMU for DSP architecture. The manufacture (TI) provides a runtime library that support posix standard IO, but it left the device level implmentation as hook function calls, like in the library source , it contains

Re: how to build QEMU with the peripheral device modules

Hi , Thanks for the hints. I get better understanding to the kconfig tool now. I added "select TI_DMA" in my DSP kconfig file. It is done. best regards, xiaolei --Original-- From:"Philippe Mathieu-Daudé"

Re: GDB get wrong debug infos on TI DSP architecture extension

Hi, Thank you for forwarding my question to developers and sharing the C6x implementation. Perhaps I should follow up with another problem I encountered. The senerio is the emulator keeps running eventhough the program it emulates has already exited. And it keeps retrieving instructions which

Hi all, I am working on a TI DSP architecture extension for QEMU. Now, we are adding GDB debugging features. We have done the following, but not sure we are on the right track : - add a xml description file in gdb-xml, without understanding the purpose of the file, why some architectures

re?? how to extend to load COFF executable image file

Hello, Thanks for the detailed explaination and insightful advise!! I firstly give a try to use objcopy from GNU binutils, but it seems the COFF file I am work on (which is generated by TI's CCS IDE) cannot be recognized. The COFF format used by TI sllightly differs from GNU's definition. So
