[Android source code analysis] bind Analysis of L2CAP, and introduction and implementation of psm and cid

After the above socke is created, we will naturally think of the following work, that is, bind. 5.6 bind Analysis of l2cap According to international practice, after the socket is built, bind is bound, haha ~~ if (l2cap_bind(sock, opts->src, server ? opts->psm : 0, opts->cid, err) This function is as follows: Static int l2cap_bind (int sock, const bdaddr_t * src, uint16_t

Shadow Map series (PCF, CSM, VSM, lvsm)

put the values 0 and 1 produced by the depth comparison in a render target, and then filter them, so that 0.2, 0 will appear in the shadow edge area. 5 .... and then generate soft shadow. However, this filtering method consumes time, especially when the number of samples is large. It is simplified to Horizontal Filtering and vertical filtering to reduce the number of samples. CSM (Convolution shadow map): convolution shadow map. This method uses sha

The next generation of Uefi BIOS "CSM" affects the installation of Windows (11)

CSM Full Name compatibility support module, a compatibility support block, is a special module of UEFI that provides compatibility for systems that do not support UEFI. Currently, the WINDOWS8 fully supports the 64-bit uefi that is not fully supported by Uefi,windows7 . Therefore, the installation of Windows7 in UEFI BIOS must turn on the CSM, most computers can be turned on automatically or manually, and a

Some Problems in cascaded shadow map (CSM)

Cascaded shadow map (CSM) is currently the mainstream Shadow technology in the engine, and the efficiency and effect are both good. It is different from the traditional shadow map in that it splits the cone into layers, and each layer separately calculates the related SM, in this way, you can avoid the disadvantages of traditional SM by rendering the shadows of large scenes. The typical CSM principle is bas

[Work accumulation] Shadow map problem summary

the A2 is 1-alpha_a1, independent of distance, but it can solve the z fighting and shadow acne when transparent objects and opaque objects are too close to each other.Above is the main problem in the work. Another simple record of something else.CsmIf all the shadows are generated on a single shadowmap, the near resolution is also lower. The CSM mainly uses multiple cascade to improve the shadow resolution near the vicinity.Previous work has also don

Analysing Bluetooth keyboard traffic with hcidump

I own a rocketfish RF-BTMKY Bluetooth keyboard and I really like it. today, I tried using hcidump to dump the Bluetooth traffic from my keyboard and see if I cocould find a pattern. hcidump is trivial to use, and can display packets in varous formats. you can also dump the packets to a file that can then be read by Wireshark. hcidump requires root access to be able to capture the packets. here is a sample capture, took while I was typing the word "test ": Debian:/home/aghaster/BT # hcidump-xHCI

802.11 protocol Intensive reading 11: Energy Saving mode (apsd,psmp,smps)

PrefaceIn the 802.11 major releases, a total of four energy-saving models were defined, and in the previous document we introduced the most basic PSM mode and some details on how it works. Since PSM was designed under the initial 802.11 protocol, it was designed with a more conservative design to ensure the most stable operational requirements. In the later 802.11 new releases, there were other energy-savin

for platform independent modeling. L PSM (platform-specific model) is modeled through PIM Mapping, and the platform-related parts are modified by PSM. With the above model, we can directly mapping to the code, and realize the synchronization between the model and the code. Depending on the implementation, the partitioning model can be driven to maturity (this part is not fully recorded, tentatively). 1.3
