Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Kernel Object Buffer Management During Linux kernel running, some kernel data structures (objects) are often used ). For example, when a thread of a process opens a file for the first time, the kernel needs to allocate a d

For the meanings of these global variables, refer to memcached startup parameters. For these global variables, take their default values directly as described in "how to read memcached sou

Fast and Effective Memory distributor for small memory blocks Translated by znrobinson Guo shilong Introduction Dynamic memory allocation is interesting. When calling malloc/free, most people will not consider the associated costs. Heap-based memory allocation is mentioned. In order to re-apply for and re-use the memory, the management of memory blocks must carry out a lot of notes, which will take a CPU cycle. When we try to write efficient code, th

Note: memory management is always the red-light area of the C/C ++ program. There are two focuses on memory management. One is the correct use of memory. For example, new and delete in C ++ should appear in pairs and use raiI to manage memory resources, auto_ptr and other aspects, many C/C ++ books use the introduction of skills. The other is the implementation of memory management, such as the slab distributor of the Linux kernel, Allocator implement

Article Title: slab distributor analysis. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Good operating system performance depends on the ability of the operating system to effectively manage resources. In the past, heap memory manager was the actual specification, but its performance was affected by the demand fo

, and it takes some time to effectively manage the idle memory. This algorithm usually has a high memory usage efficiency (allocating the required memory), but it takes more time to manage the heap. Another method is calledBuddy Memory AllocationIs a faster memory allocation technology, which divides the memory into two power-to-power partitions and uses the best-fit method to allocate memory requests. When a user releases the memory, the user checks the buddy block to check whether the adjacent

For most developers, the system memory allocation is a black box, which is called by several APIs. If you have one, you can give it to me. If you do not have one, you can find another solution. Before coming to UC, I thought so. When I went deep into the field, I found that this field is also a great competition. Memory Allocator (Memory Allocator) at the operating system level, at the application level, designed for real-time systems, and designed for service programs. However, they confirm the

of the best-fit method results in a waste of memory. This article focuses on Linux kernel memory management, especiallySlab allocation. Slab Cache The slab distributor used in Linux is based on an algorithm first introduced by Jeff bonwick for the SunOS operating system. Jeff's distributor is centered around the object cache. In the kernel, a large amount of memory is allocated to a limited set of objects

We know that Redis does not implement its own memory pool and does not add its own stuff to the standard system memory distributor. Therefore, the performance and fragment rate of the system memory distributor are We know that Redis does not implement its own memory pool and does not add its own stuff to the standard system memory distributor. Therefore, the perf

We knowRedisThere is no self-implemented memory pool, and nothing else is added to the standard system memory distributor. Therefore, the performance and fragment rate of the system memory distributor may affect Redis performance. In Redis's zmalloc. c source code, we can see the following code: 48 /* Explicitly override malloc/free etc when using tcmalloc. */ 49 #if defined(USE_TCMALLOC) 50 #define malloc

Set active register, as its name implies, is to set an interrupt to active state, and clear active register is to clear the active state. here we need to explain some concepts of the interrupt state: Active: If the processor is processing the interrupt processing function at this time, we can say that the interrupt is active at this time; Pending status: if an interrupt is generated but not processed by the processor, we can say that the interrupt is in pending status; Inactive status: if

this register relative to Distributor is 0x300-0x37c . The calculation method is:For interrupt ID m , when DIV and MOD is the integer division and modulo operations:the corresponding Gicd_isactivern number, N , is given by N = m DIVThe offset of the required Gicd_isactivern is (0x300+ ()The bit number of the required set-active bit in this register is mMOD.For the clear active register, write 1 is valid. Write 0 is invalid. The read-out value represe
