That is, those where the data is pushed to the consumer. 28 connected to an external DMA controller which is supported by the 36 Provides a way to bonding when an IIO device has a direct connection 47 no buffer events so it is up to userspace to work out how`
/linux-6.15/Documentation/userspace-api/fwctl/
D	fwctl.rst	13 software-defined pieces of hardware. The evolution of this approach is largely a 14 reaction to Moore's Law where a chip tape out is now highly expensive, and the 15 chip design is extremely large. Replacing fixed HW logic with a flexible and 16 tightly coupled FW/HW combination is an effective risk mitigation against chip 17 respin. Problems in the HW design can be counteracted in device FW. This is 41 support, and FW-driven functionality that is not well suited to “generic” 46 fwctl is aimed at the common device design pattern where the OS and FW 52 fit into any specific subsystem. For example, a HW RAID controller is primarily 61 fwctl's purpose is to define a common set of limited rules, described below, 73 It is not an avenue to access random kernel internals, or other operating system [all …]

It is recommended that you choose a meaningful tag name, 30 practice is to include in the name an indicator of the subsystem of origin 49 so outline what is contained here, why it should be merged, and what, if 57 Anyway, at least to me, the important part is the message. I want 63 Note that if there is something odd about the pull request, that 95 Here is the big char/misc patch set for the 4.15-rc1 merge window. 96 Contained in here is the normal set of new functions added to all 109 There is a Kconfig option to force these to be enabled [all …]

D	static-keys.rst	9 The use of 'struct static_key' directly, is now DEPRECATED. In addition 10 static_key_{true,false}() is also DEPRECATED. IE DO NOT use the following:: 58 Although the overhead of this check is small, it increases when the memory 62 tracepoints are often dormant (disabled) and provide no direct kernel 63 functionality. Thus, it is highly desirable to reduce their impact as much as 80 For example, if we have a simple branch that is disabled by default:: 87 straight-line code path. When the branch is 'flipped', we will patch the 89 out-of-line true branch. Thus, changing branch direction is expensive but 90 branch selection is basically 'free'. That is the basic tradeoff of this 93 This lowlevel patching mechanism is called 'jump label patching', and it gives [all …]

Note that there is only one eBPF program (== one 47 Operation is 64-bit, because on 64-bit architectures, pointers are also 50 ABI, thus, there won't be able to use a direct eBPF register to HW register 52 register in and out of the function, which is complex, bug prone and slow. 53 Another reason is the use of atomic 64-bit counters. 76 is preserved across the call. 103 If f2 is JITed and the pointer stored to ``_f2``.
