1 1.1.2.24 pgoyette /* $NetBSD: TODO.compat-module,v 1.1.2.24 2019/01/18 05:42:34 pgoyette Exp $ */ 2 1.1.2.1 pgoyette 3 1.1.2.1 pgoyette DONE 4 1.1.2.1 pgoyette ---- 5 1.1.2.11 pgoyette 1. Removed the building of the compat library - it is no longer needed. 6 1.1.2.1 pgoyette 7 1.1.2.1 pgoyette 2. Reverted some intentional auto-load breakage for loading the sysv_ipc 8 1.1.2.1 pgoyette module; the breakage was introduced as the fix for the above-mentioned 9 1.1.2.1 pgoyette build breakage. 10 1.1.2.1 pgoyette 11 1.1.2.1 pgoyette 3. Split the sysv_ipc compat routines into their own compat_sysv module. 12 1.1.2.1 pgoyette 13 1.1.2.1 pgoyette 4. Resolved some inter-module dependencies. 14 1.1.2.1 pgoyette 15 1.1.2.1 pgoyette 5. Extracted some net/if.c compat routines into the compat module, and 16 1.1.2.1 pgoyette replaced the originals with indirect (vectored) function calls. 17 1.1.2.1 pgoyette 18 1.1.2.1 pgoyette 6. Reconfirmed existing compat-module dependencies, and update the 19 1.1.2.1 pgoyette defopt/defflag lines in the config files* as needed, to insure that 20 1.1.2.1 pgoyette built-in dependencies get resolved. 21 1.1.2.1 pgoyette 22 1.1.2.24 pgoyette 7. Fixed limits on the number of module dependencies and maximum 23 1.1.2.1 pgoyette recursion level have been removed. Previous code for reporting 24 1.1.2.1 pgoyette module status to userland has been versioned and moved to the 25 1.1.2.24 pgoyette (new) compat_80 module. 26 1.1.2.1 pgoyette 27 1.1.2.1 pgoyette 8. The old monolithic compat module has been broken into multiple 28 1.1.2.1 pgoyette modules, one for each old NetBSD version. The monolithic module 29 1.1.2.2 pgoyette is no longer available. 30 1.1.2.1 pgoyette 31 1.1.2.1 pgoyette Similarly, the compat_sysv module has also been split into several 32 1.1.2.1 pgoyette version-specific modules, and the mini-monolithic compat_sysv module 33 1.1.2.2 pgoyette is no longer provided. 34 1.1.2.1 pgoyette 35 1.1.2.1 pgoyette 9. syscalls.master has been updated to autoload the version-specific 36 1.1.2.1 pgoyette compat modules rather than the monolithic modules. 37 1.1.2.1 pgoyette 38 1.1.2.1 pgoyette 10. Separated COMPAT_BSDPTY stuff, allowing the COMPAT_60 module to be 39 1.1.2.1 pgoyette built regardless. 40 1.1.2.1 pgoyette 41 1.1.2.5 pgoyette 11. Implemented a MP-safe mechanism for installing and removing function 42 1.1.2.5 pgoyette pointers. Thanks to riastradh@ for the template code. 43 1.1.2.5 pgoyette 44 1.1.2.6 pgoyette 12. Replace version-specific parts of the compat_netbsd32 module (and 45 1.1.2.6 pgoyette also the compat_netbsd32_sysv module) with individual modules. Update 46 1.1.2.24 pgoyette dependencies accordingly. (Done, but see #19 below.) 47 1.1.2.6 pgoyette 48 1.1.2.8 pgoyette 13. Finished splitting the vnd_30 and vnd_50 compat code into separate 49 1.1.2.8 pgoyette modules. 50 1.1.2.8 pgoyette 51 1.1.2.8 pgoyette 14. Cleaned up some previous vectored routines (related to if_43.c) to 52 1.1.2.8 pgoyette use the MP-safe mechanism. 53 1.1.2.7 pgoyette 54 1.1.2.24 pgoyette 15. Organized (some of) the netbsd32 machine-dependent code to fit a 55 1.1.2.24 pgoyette common build framework, and split version-specific code from baseline 56 1.1.2.24 pgoyette code as needed. 57 1.1.2.1 pgoyette 58 1.1.2.22 pgoyette 16. The rtsock.c code has been split into two separate source files, 59 1.1.2.24 pgoyette one for use in -current and one which is shared with COMPAT_50 (the 60 1.1.2.24 pgoyette code is shared with -current, but macros are used to define version- 61 1.1.2.24 pgoyette specific routine names and variable types). 62 1.1.2.19 pgoyette 63 1.1.2.1 pgoyette TODO - Not required for branch merge 64 1.1.2.1 pgoyette ------------------------------------ 65 1.1.2.19 pgoyette 17. Audit the entire code base for any remaining embedded #ifdef's for 66 1.1.2.1 pgoyette COMPAT_xx. When found, move the actual compat code into the compat 67 1.1.2.1 pgoyette hierarchy and replace originals with indirect (vectored) calls. 68 1.1.2.1 pgoyette 69 1.1.2.18 pgoyette 18. The compat_60 module still needs some work for XEN systems. We 70 1.1.2.1 pgoyette probably need some build infrastructure changes to ensure that 71 1.1.2.1 pgoyette XEN (and, for i386, XEN-PAE) modules are build with the correct 72 1.1.2.1 pgoyette macros defined and with -I directories specified in the same order 73 1.1.2.1 pgoyette as for building kernels. See PR port-xen/53130. This currently 74 1.1.2.1 pgoyette prevents loading of micro-code updates for amd64 processors running 75 1.1.2.1 pgoyette XEN kernels. This limitation also exists on HEAD. 76 1.1.2.1 pgoyette 77 1.1.2.18 pgoyette 19. There seems to be quite a bit of MD compat_xx code, in the various 78 1.1.2.1 pgoyette sys/arch/ directories. I haven't yet looked at any of this. But it 79 1.1.2.1 pgoyette seems to me that the MI compat build infrastructure should have some 80 1.1.2.1 pgoyette mechanism to "reach over" to the MD code, #include a Makefile.inc file, 81 1.1.2.1 pgoyette and perhaps define something to enable the MI modcmd code to call a 82 1.1.2.1 pgoyette compat_xx_MD_init() routine. 83 1.1.2.1 pgoyette 84 1.1.2.1 pgoyette Note also that there are a few bits of MD code that is COMPAT_44 85 1.1.2.1 pgoyette related. (The only bit of MI COMPAT_44 code is in the single module 86 1.1.2.1 pgoyette shared by COMPAT_43 and COMPAT_09.) This affects the cesfic, hp300, 87 1.1.2.1 pgoyette news68k, and x68k platforms, all in their respective machdep.c 88 1.1.2.1 pgoyette source file. Additionally, the zaurus platform defines COMPAT_44 in 89 1.1.2.1 pgoyette its INSTALL kernel configuration - but no other configuration files! 90 1.1.2.1 pgoyette 91 1.1.2.1 pgoyette As far as I can tell, none of the MD compat code is currently built 92 1.1.2.1 pgoyette into the monolithic COMPAT module on HEAD. Thus, its absence from 93 1.1.2.1 pgoyette any of the version-specific modules is not a regression. 94 1.1.2.1 pgoyette 95 1.1.2.23 pgoyette 20. For compat_50, there are some things in dev/gpio and dev/wscons/wsmux 96 1.1.2.23 pgoyette that I haven't been able to cleanly separate. These items are not 97 1.1.2.23 pgoyette currently included in the monolithic COMPAT module on HEAD, so lack of 98 1.1.2.23 pgoyette integration on the branch is not a regression. 99 1.1.2.15 pgoyette 100 1.1.2.18 pgoyette 21. Find all the remaining dependencies on the compat_utils routines and 101 1.1.2.15 pgoyette deal with them appropriately. For now, we simply ensure that they 102 1.1.2.15 pgoyette are included in every kernel via 'options COMPAT_UTILS' in file 103 1.1.2.15 pgoyette sys/conf/std 104 1.1.2.20 pgoyette 105
