Qualcomm msm8260 Excellent: high frequency, generally about 30% higher than other brand products during the same period, resulting in improved CPU integer performance. General document processing and daily applications can reflect integer performance.
Lack: 1. Power Consumption. the power consumption of asynchronous dual-core under the 28 nm design should be lower than that of other A9, but the power consumption of 45 nm is higher than that of other A
Qualcomm takes lead as 4g patent holder
Qualcomm looks set to be the leading patent holder in 4G wireless communications after recording 24% of ETSI declarations surrounding LTE, as well as 16% of the 26,000 patents that have potential relevance to 4G technologies generally, including WiMax.
Other notable players in the LTE field include interdigital (18%), Huawei (10%), lg (9%), Nokia (9%) and Samsung (7
According to Reuters September 15, Qualcomm's chief executive predicts that the first 5G mobile phone to meet next-generation mobile standards will be available in the world's major markets in 2019, a year earlier than forecast.Steven Mollenkov, chief executive of Qualcomm, the world's top smartphone chip maker, said in an interview that consumer and business demand is growing, forcing 5G mobile phones to accelerate the popularity of the original 2020
The following is an initialization process analysis of the MMC host Controller drive on the Qualcomm 8x50.
Analysis based on kernel version 2.6.29 (the main code is DRIVER/MMC/MSM_SDCC.C and msm_sdcc.h and Arch Code)
1. Types of buses involved in MMC
The code in the MMC directory mainly involves three kinds of buses, one is platform bus, the MMC host controller as a kind of platform device, it is need to register to the platform on.

Solve the problem that Qualcomm Atheros AR8161 Gigabit Ethernet NIC fails in Linux.
The NIC Of My Dell I2330R-168 integrated computer broke down after upgrading a kernel version.
ifconfig eth0eth0: flags=4163
Now the arch linux is installed, and the kernel is updated to the latest version.
uname -a4.4.1-2-ARCH #1 SMP PREEMPT Wed Feb 3 13:12:33 UTC
However, this problem still exists.
I suddenly thought that I should go to the kernel site to find the

Then we need to extract the patches for this time period, then let's see which updates are available, and then consider whether to merge or not.
