address of kernel space, but for various reasons, concrete arch can specify an OFFSET (Text_offset) when compiling the kernel. For ARM64 It is 512KB (0x00080000), so the compiled kernel runs on the 0xffff8000_00080000 address. When the system starts, bootloader will kernel image copy to main memory, and of course, like the virtual address space, kernel image does not copy to the first address of main memory, Also maintains an offset of the same size.

In order to support 64-bit, please replace this file directly to the corresponding Lib directory, it is necessary to change the macro definition in NETON_MATRIX_IMPL.C,In the PLATFORM/IOS/EAGLVIEW.MMModify in Neon_matrix_impl.c#if defined (__arm_neon__)for # if defined (_arm_arch_7)also have Third_party support for curl under the directory. So I tidied up and packaged him up as a zip file to make it easy to replace it with a direct download.Please download for freehttp://download.csdn.net/detail

Problem description Today testers test the integration version in addition to a bug: about the Huawei Mate 8 Mobile Android 6.0 system running just the version of the test, there is a flash bug, and Xiaomi 4 mobile phone Android 6.0 system did not appear any bug, run well. Later view the code of my relevant module, found that I integrated version of the relevant module code and branch version of the code of the relevant module is exactly the same, that is to say I merge the branch code

First, prefaceProcess switching is a complex process, and this article is not intended to describe in detail all aspects of the process switching, but rather to focus on a little bit of knowledge in process switching: the processing of TLB. To be able to articulate this problem, we describe in the second chapter some of the TLB-related details in a single CPU scenario, and the third chapter advances to the multi-core scenario, at which point the theoretical part ends. In the second chapter and t

IOS lib (. a) Library conflict solutionWhen a third-party lib (. a) Library is introduced, it is often caused by a. o conflict because the third-party lib library introduces the same open source code as your existing project. I would like to say that such open-source code with high usage should not be included in the lib library. If you want to include the source code, you should change the name. However, there is no way for us to separate them. 1. view the supported framework types of the lib l
