1 | The following is a list of files and features that are going to be |
2 | removed in the kernel source tree. Every entry should contain what | |
3 | exactly is going away, why it is happening, and who is going to be doing | |
4 | the work. When the feature is removed from the kernel, it should also | |
5 | be removed from this file. | |

9 | What: PRISM54 |
10 | When: 2.6.34 | |
11 | ||
12 | Why: prism54 FullMAC PCI / Cardbus devices used to be supported only by the | |
13 | prism54 wireless driver. After Intersil stopped selling these | |
14 | devices in preference for the newer more flexible SoftMAC devices | |
15 | a SoftMAC device driver was required and prism54 did not support | |
16 | them. The p54pci driver now exists and has been present in the kernel for | |
17 | a while. This driver supports both SoftMAC devices and FullMAC devices. | |
18 | The main difference between these devices was the amount of memory which | |
19 | could be used for the firmware. The SoftMAC devices support a smaller | |
20 | amount of memory. Because of this the SoftMAC firmware fits into FullMAC | |
21 | devices's memory. p54pci supports not only PCI / Cardbus but also USB | |
22 | and SPI. Since p54pci supports all devices prism54 supports | |
23 | you will have a conflict. I'm not quite sure how distributions are | |
24 | handling this conflict right now. prism54 was kept around due to | |
25 | claims users may experience issues when using the SoftMAC driver. | |
26 | Time has passed users have not reported issues. If you use prism54 | |
27 | and for whatever reason you cannot use p54pci please let us know! | |

38 | What: IRQF_SAMPLE_RANDOM |
39 | Check: IRQF_SAMPLE_RANDOM | |
40 | When: July 2009 | |
41 | ||
42 | Why: Many of IRQF_SAMPLE_RANDOM users are technically bogus as entropy | |
43 | sources in the kernel's current entropy model. To resolve this, every | |
44 | input point to the kernel's entropy pool needs to better document the | |
45 | type of entropy source it actually is. This will be replaced with | |
46 | additional add_*_randomness functions in drivers/char/random.c | |

52 | What: Deprecated snapshot ioctls |
53 | When: 2.6.36 | |
54 | ||
55 | Why: The ioctls in kernel/power/user.c were marked as deprecated long time | |
56 | ago. Now they notify users about that so that they need to replace | |
57 | their userspace. After some more time, remove them completely. | |

6ee7d330 | 63 | What: The ieee80211_regdom module parameter |
8a5117d8 | 64 | When: March 2010 / desktop catchup |
6ee7d330 LR |
65 | |
66 | Why: This was inherited by the CONFIG_WIRELESS_OLD_REGULATORY code, | |
67 | and currently serves as an option for users to define an | |
68 | ISO / IEC 3166 alpha2 code for the country they are currently | |
69 | present in. Although there are userspace API replacements for this | |
70 | through nl80211 distributions haven't yet caught up with implementing | |
71 | decent alternatives through standard GUIs. Although available as an | |
72 | option through iw or wpa_supplicant its just a matter of time before | |
73 | distributions pick up good GUI options for this. The ideal solution | |
74 | would actually consist of intelligent designs which would do this for | |
75 | the user automatically even when travelling through different countries. | |
76 | Until then we leave this module parameter as a compromise. | |
77 | ||
78 | When userspace improves with reasonable widely-available alternatives for | |
79 | this we will no longer need this module parameter. This entry hopes that | |
80 | by the super-futuristically looking date of "March 2010" we will have | |
81 | such replacements widely available. | |

87 | What: CONFIG_WIRELESS_OLD_REGULATORY - old static regulatory information |
88 | When: March 2010 / desktop catchup | |
89 | ||
b2e1b302 LR |
90 | Why: The old regulatory infrastructure has been replaced with a new one |
91 | which does not require statically defined regulatory domains. We do | |
92 | not want to keep static regulatory domains in the kernel due to the | |
93 | the dynamic nature of regulatory law and localization. We kept around | |
94 | the old static definitions for the regulatory domains of: | |
8a5117d8 | 95 | |
b2e1b302 LR |
96 | * US |
97 | * JP | |
98 | * EU | |
8a5117d8 | 99 | |
b2e1b302 | 100 | and used by default the US when CONFIG_WIRELESS_OLD_REGULATORY was |
8a5117d8 LR |
101 | set. We will remove this option once the standard Linux desktop catches |
102 | up with the new userspace APIs we have implemented. | |

471d0558 | 108 | What: dev->power.power_state |
1ebfd79e PM |
109 | When: July 2007 |
110 | Why: Broken design for runtime control over driver power states, confusing | |
111 | driver-internal runtime power management with: mechanisms to support | |
112 | system-wide sleep state transitions; event codes that distinguish | |
113 | different phases of swsusp "sleep" transitions; and userspace policy | |
114 | inputs. This framework was never widely used, and most attempts to | |
115 | use it were broken. Drivers should instead be exposing domain-specific | |
116 | interfaces either to kernel or to userspace. | |

121 | What: Video4Linux API 1 ioctls and from Video devices. |
122 | When: July 2009 | |
123 | Files: include/linux/videodev.h | |
124 | Check: include/linux/videodev.h | |
11a5a10e | 125 | Why: V4L1 AP1 was replaced by V4L2 API during migration from 2.4 to 2.6 |
875c296b MCC |
126 | series. The old API have lots of drawbacks and don't provide enough |
127 | means to work with all video and audio standards. The newer API is | |
128 | already available on the main drivers and should be used instead. | |
129 | Newer drivers should use v4l_compat_translate_ioctl function to handle | |
130 | old calls, replacing to newer ones. | |
131 | Decoder iocts are using internally to allow video drivers to | |
132 | communicate with video decoders. This should also be improved to allow | |
133 | V4L2 calls being translated into compatible internal ioctls. | |
11a5a10e MCC |
134 | Compatibility ioctls will be provided, for a while, via |
135 | v4l1-compat module. | |

140 | What: PCMCIA control ioctl (needed for pcmcia-cs [cardmgr, cardctl]) |
141 | When: November 2005 | |
142 | Files: drivers/pcmcia/: pcmcia_ioctl.c | |
143 | Why: With the 16-bit PCMCIA subsystem now behaving (almost) like a | |
144 | normal hotpluggable bus, and with it using the default kernel | |
145 | infrastructure (hotplug, driver core, sysfs) keeping the PCMCIA | |
146 | control ioctl needed by cardmgr and cardctl from pcmcia-cs is | |
147 | unnecessary, and makes further cleanups and integration of the | |
148 | PCMCIA subsystem into the Linux kernel device driver model more | |
149 | difficult. The features provided by cardmgr and cardctl are either | |
150 | handled by the kernel itself now or are available in the new | |
151 | pcmciautils package available at | |

157 | What: sys_sysctl |
158 | When: September 2010 | |
159 | Option: CONFIG_SYSCTL_SYSCALL | |
160 | Why: The same information is available in a more convenient from | |
161 | /proc/sys, and none of the sysctl variables appear to be | |
162 | important performance wise. | |
163 | ||
164 | Binary sysctls are a long standing source of subtle kernel | |
165 | bugs and security issues. | |
166 | ||
167 | When I looked several months ago all I could find after | |
168 | searching several distributions were 5 user space programs and | |
169 | glibc (which falls back to /proc/sys) using this syscall. | |
170 | ||
171 | The man page for sysctl(2) documents it as unusable for user | |
172 | space programs. | |
173 | ||
174 | sysctl(2) is not generally ABI compatible to a 32bit user | |
175 | space application on a 64bit and a 32bit kernel. | |
176 | ||
177 | For the last several months the policy has been no new binary | |
178 | sysctls and no one has put forward an argument to use them. | |
179 | ||
180 | Binary sysctls issues seem to keep happening appearing so | |
181 | properly deprecating them (with a warning to user space) and a | |
182 | 2 year grace warning period will mean eventually we can kill | |
183 | them and end the pain. | |
184 | ||
185 | In the mean time individual binary sysctls can be dealt with | |
186 | in a piecewise fashion. | |

194 | Files: arch/*/kernel/*_ksyms.c | |
f0a594c1 | 195 | Check: kernel_thread |
ac515898 CH |
196 | Why: kernel_thread is a low-level implementation detail. Drivers should |
197 | use the <linux/kthread.h> API instead which shields them from | |
198 | implementation details and provides a higherlevel interface that | |
199 | prevents bugs and code duplication | |

206 | The transition config option will also be removed at the same time. | |
207 | When: before 2.6.19 | |
208 | Why: Unused symbols are both increasing the size of the kernel binary | |

216 | Why: The stacking of class devices makes these values misleading and |

251 | |
252 | Why: The i386/x86_64 merge provides a symlink to the old bzImage | |

269 | What: GPIO autorequest on gpio_direction_{input,output}() in gpiolib |
270 | When: February 2010 | |
271 | Why: All callers should use explicit gpio_request()/gpio_free(). | |
272 | The autorequest mechanism in gpiolib was provided mostly as a | |
273 | migration aid for legacy GPIO interfaces (for SOC based GPIOs). | |
274 | Those users have now largely migrated. Platforms implementing | |
275 | the GPIO interfaces without using gpiolib will see no changes. | |

eb189d8b | 279 | What: b43 support for firmware revision < 410 |
c557289c MB |
280 | When: The schedule was July 2008, but it was decided that we are going to keep the |
281 | code as long as there are no major maintanance headaches. | |
282 | So it _could_ be removed _any_ time now, if it conflicts with something new. | |
eb189d8b MB |
283 | Why: The support code for the old firmware hurts code readability/maintainability |
284 | and slightly hurts runtime performance. Bugfixes for the old firmware | |

290 | What: /sys/o2cb symlink |
291 | When: January 2010 | |
292 | Why: /sys/fs/o2cb is the proper location for this information - /sys/o2cb | |
293 | exists as a symlink for backwards compatibility for old versions of | |
294 | ocfs2-tools. 2 years should be sufficient time to phase in new versions | |

301 | resource limits | |
302 | When: 2.6.31 | |
303 | Why: Non root users need to be part of /proc/sys/vm/hugetlb_shm_group or | |
304 | have CAP_IPC_LOCK to be able to allocate shm segments backed by | |
305 | huge pages. The mlock based rlimit check to allow shm hugetlb is | |
306 | inconsistent with mmap based allocations. Hence it is being | |

358 | What: fakephp and associated sysfs files in /sys/bus/pci/slots/ |
359 | When: 2011 | |
360 | Why: In 2.6.27, the semantics of /sys/bus/pci/slots was redefined to | |
361 | represent a machine's physical PCI slots. The change in semantics | |
362 | had userspace implications, as the hotplug core no longer allowed | |
363 | drivers to create multiple sysfs files per physical slot (required | |
364 | for multi-function devices, e.g.). fakephp was seen as a developer's | |
365 | tool only, and its interface changed. Too late, we learned that | |
366 | there were some users of the fakephp interface. | |
367 | ||
368 | In 2.6.30, the original fakephp interface was restored. At the same | |
369 | time, the PCI core gained the ability that fakephp provided, namely | |
370 | function-level hot-remove and hot-add. | |
371 | ||
372 | Since the PCI core now provides the same functionality, exposed in: | |
373 | ||
374 | /sys/bus/pci/rescan | |
375 | /sys/bus/pci/devices/.../remove | |
376 | /sys/bus/pci/devices/.../rescan | |
377 | ||
378 | there is no functional reason to maintain fakephp as well. | |
379 | ||
380 | We will keep the existing module so that 'modprobe fakephp' will | |
381 | present the old /sys/bus/pci/slots/... interface for compatibility, | |
382 | but users are urged to migrate their applications to the API above. | |
383 | ||
384 | After a reasonable transition period, we will remove the legacy | |
385 | fakephp interface. | |

417 | When: August 2010 | |
418 | Why: OSS sound_core grabs all legacy minors (0-255) of SOUND_MAJOR | |
419 | (14) and requests modules using custom sound-slot/service-* | |
420 | module aliases. The only benefit of doing this is allowing | |
421 | use of custom module aliases which might as well be considered | |
422 | a bug at this point. This preemptive claiming prevents | |
423 | alternative OSS implementations. | |
424 | ||
425 | Till the feature is removed, the kernel will be requesting | |
426 | both sound-slot/service-* and the standard char-major-* module | |
427 | aliases and allow turning off the pre-claiming selectively via | |
428 | CONFIG_SOUND_OSS_CORE_PRECLAIM and soundcore.preclaim_oss | |
429 | kernel parameter. | |
430 | ||
431 | After the transition phase is complete, both the custom module | |
432 | aliases and switches to disable it will go away. This removal | |
433 | will also allow making ALSA OSS emulation independent of | |
434 | sound_core. The dependency will be broken then too. | |

439 | What: Support for VMware's guest paravirtuliazation technique [VMI] will be | |
440 | dropped. | |
441 | When: 2.6.37 or earlier. | |
442 | Why: With the recent innovations in CPU hardware acceleration technologies | |
443 | from Intel and AMD, VMware ran a few experiments to compare these | |
444 | techniques to guest paravirtualization technique on VMware's platform. | |
445 | These hardware assisted virtualization techniques have outperformed the | |
446 | performance benefits provided by VMI in most of the workloads. VMware | |
447 | expects that these hardware features will be ubiquitous in a couple of | |
448 | years, as a result, VMware has started a phased retirement of this | |
449 | feature from the hypervisor. We will be removing this feature from the | |
450 | Kernel too. Right now we are targeting 2.6.37 but can retire earlier if | |
451 | technical reasons (read opportunity to remove major chunk of pvops) | |
452 | arise. | |
453 | ||
454 | Please note that VMI has always been an optimization and non-VMI kernels | |
455 | still work fine on VMware's platform. | |
456 | Latest versions of VMware's product which support VMI are, | |
457 | Workstation 7.0 and VSphere 4.0 on ESX side, future maintainence | |
458 | releases for these products will continue supporting VMI. | |
459 | ||

473 | What: Support for lcd_switch and display_get in asus-laptop driver |
474 | When: March 2010 | |
475 | Why: These two features use non-standard interfaces. There are the | |
476 | only features that really need multiple path to guess what's | |
477 | the right method name on a specific laptop. | |
478 | ||
479 | Removing them will allow to remove a lot of code an significantly | |
480 | clean the drivers. | |
481 | ||
482 | This will affect the backlight code which won't be able to know | |
483 | if the backlight is on or off. The platform display file will also be | |
484 | write only (like the one in eeepc-laptop). | |
485 | ||
486 | This should'nt affect a lot of user because they usually know | |
487 | when their display is on or off. | |

536 | Why: Duplicate functionality with the gspca_zc3xx driver, zc0301 only | |
537 | supports 2 USB-ID's (because it only supports a limited set of | |
538 | sensors) wich are also supported by the gspca_zc3xx driver | |

545 | When: 2.6.35 | |
546 | Files: drivers/input/keyboard/{corgi,spitz,tosa}kbd.c | |
547 | Why: We now have a generic GPIO based matrix keyboard driver that | |
548 | are fully capable of handling all the keys on these devices. | |
549 | The original drivers manipulate the GPIO registers directly | |
550 | and so are difficult to maintain. | |

558 | Why: The corgi touchscreen is now deprecated in favour of the generic | |
559 | ads7846.c driver. The noise reduction technique used in corgi_ts.c, | |
560 | that's to wait till vsync before ADC sampling, is also integrated into | |
561 | ads7846 driver now. Provided that the original driver is not generic | |
562 | and is difficult to maintain, it will be removed later. | |
