From 7b76bfc86757ca5e7b0a62f50003752da77c115b Mon Sep 17 00:00:00 2001 From: Dick Streefland Date: Tue, 6 Oct 2009 22:35:40 +0200 Subject: kconfig: simplification of scripts/extract-ikconfig I've rewritten the extract-ikconfig script to extract the kernel configuration from a kernel compiled with CONFIG_IKCONFIG. The main motivation for the rewrite was to remove the dependency on the external C program binoffset.c, which is compiled on the initial run. The binoffset executable is invoked with a relative path, which means that the old script can only be run from the top of the kernel tree, and only when you have write permission in the scripts directory. The new script uses tr/grep/tail/zcat only, and can be invoked from anywhere. The binoffset.c program has been removed. This script requires GNU grep 2.5 (released 2002-03-13) or higher, because the -o option was introduced in that version.

That is, the above example will look for "embedded_board_lsmod" in the directory that the binary will be built in (the O=dir directory).

Verified that aliases for these modules are generated correctly: drivers/media/radio/radio-sf16fmi.c drivers/net/ne.c drivers/net/3c515.c drivers/net/smc-ultra.c drivers/pcmcia/i82365.c drivers/scsi/aha1542.c drivers/scsi/aha152x.c drivers/scsi/sym53c416.c drivers/scsi/g_NCR5380.c Tested with RTL8019AS (ne), AVA-1505AE (aha152x) and dtc436e (g_NCR5380) cards - they now work automatically. Generate pnp:d aliases for isapnp_device_tables. This allows udev to load these modules automatically.

This can include signers that simply report an issue or test a patch. Signers that use this tag are not necessarily good candidates to review new patches. This patch allows get_maintainers to optionally restrict output to only signatures that use Signed-off-by:, Acked-by:, or Reviewed-by:. Signed-off-by: is included because those are people who are responsible for the code. Acked-by: is questionable, but as signers that use this tag tend to be active linux gatekeepers, false positives are tolerable. Reviewed-by: is included because signers responsible for the code thought that the review feedback for a changeset by that signer was valuable. This patch has been modified from Florian's original submission to change the supported signature types to the canonical forms and use slightly different spacing. A couple of spacing issues were also corrected in the original source. The command line argument was also renamed.

The effect being, that only certain (currently Signed-Off-By:, Acked-by: and Reviewed-By:) tags are used to get adresses of potential maintainers. Motivated is this change by the desire to not 'spam' people unnecessary: A Tested-By or a Reported-By is not ment as a hint that those people want to/are able to review patches to the code in question. In a quest to find resilient statistics for this i came up with this: I produced a list of all the tag-signers not already covered with a signed-off/acked/reviewed tag somewhere in the last year of git history. Those were 650 addresses of "assumed non-developers". And to check if those "assumed non-developers" are professional testers/reporters worth cc'ing, i then counted their total appearences in the git log: 469 were mentioned only once. 123 were mentioned twice. 38 three times 8 four times 5 six times 5 five times 1 eight times 1 fourteen times I believe this supports my thesis, that the ''non-maintainer-tags'' are not actively useful for patch-review. (except probably the guy mentioned fourteen times...) But of course one could also find arguments to poke holes in this statistics, for example does this statistic not include code-locality: A tested-by on a patch that touches some specific piece of code can be more worth than a signed-off in another part of the tree. But... let's play it safe and let's err on the "safe" side meaning to not spam those people when in doubt. We already have the signed-off's and Maintainers file. So this should be ok. And if need be, the maintainers can always forward the patch.

The initial pass at the generic ABI assumed that wait4() could be easily expressed using waitid(). Although it's true that wait4() can be built on waitid(), it's awkward enough that it makes more sense to continue to include wait4 in the generic syscall ABI. Since there is already a deprecated wait4 in the ABI, this change converts that wait4 into old_wait, and puts wait4 in the next available slot for new supported syscalls, after the platform-specific syscalls at number 260.

Currently, the "depends on" clauses are used in calculating the visibility but they do not affect the reverse dependencies in any way. The patch introduces additional tracking of the "depends on" statements and prints a warning on selecting an option if its direct dependencies are not met.

(dot) builtin. While the former is supported only by bash, the latter is specified in POSIX and works fine with all POSIX-compliant shells I am aware of. The '$_' special parameter is specific to bash. It is partially supported in dash too but it always evaluates to the current script path (which causes the script to enter a loop recursively re-executing itself). This is why I have replaced the two occurences of '$_' with the explicit parameter. The 'local' builtin is another example of bash-specific code. Although it is supported by all POSIX-compliant shells I am aware of, it is not part of POSIX specification and thus the code should not rely on it assigning a specific value to the local variable. Moreover, the 'posh' shell has a limited version of 'local' builtin not supporting direct variable assignments. Thus, I have broken one of the 'local' declarations down into a (non-POSIX) 'local' declaration and a plain (POSIX-compliant) variable assignment.

However, I think the patch is still a good idea, to avoid future problems if _mcount were to ever have its address taken in normal code. This is what I originally saw: Although arch/mips/kernel/ftrace.c is built without -pg, and thus contains no calls to _mcount, it does use the address of _mcount in ftrace_make_nop(). This was causing relocations to be emitted for _mcount which recordmcount.pl erronously took to be _mcount call sites. The result was that the text of ftrace_make_nop() would be patched with garbage leading to a system crash. In non-module code, all _mcount call sites will have R_MIPS_26 relocations, so we restrict $mcount_regex to only match on these.

Take the following Kconfig as an example: config MODULES def_bool y config FOO def_tristate m With no .config, the following configuration is generated: CONFIG_MODULES=y CONFIG_FOO=y With an empty .config, the following: CONFIG_MODULES=y CONFIG_FOO=m Tristate choice statements can also exhibit the problem, due to having an implicit rev_dep (select) containing "m". The problem is that MODULES is never evaluted in conf_read_simple() unless there's a .config. The following patch fixes this.

So drop the single letter options in favour of long options. The long options are named equal to what we know from the make target.

The config symbols are saved in the same order as they appear in the menu structure so it should be possible to map them to the relevant menus if desired. The implementation was tested against several minimal configs for arm which was created using brute-force. There was one regression related to default numbers which had their valid range further limited by another symbol. Sample: config FOO int "foo" default 4 config BAR int "bar" range 0 FOO If FOO is set to 3 then BAR cannot take a value higher than 3. But the current implementation will set BAR equal to 4. This is seldomly used and the final configuration is OK, and the fix was non-trivial. So it was documented in the code and left as is.

Introduce a new set of variables KBUILD_{A,C,LD}FLAGS_MODULE that is used by arch specific files and free up {A,C,LD}FLAGS_MODULE so they can be assigned on the command line. All arch Makefiles that used the old variables has been updated. Note: Previously we had a MODFLAGS variable for both AS and CC. But in favour of consistency this was dropped. So in some cases arch Makefile has one assignmnet replaced by two assignmnets. Note2: MODFLAGS was not documented and is dropped without any notice. I do not expect much/any breakage from this.

Introduce a new set of variables KBUILD_{A,C}FLAGS_KERNEL that is used by arch specific files and free up {A,C}FLAGS_KERNEL so they can be assigned on the command line. All arch Makefiles that used the old variables has been updated.

In a very annoying way. I just did a quick git bisect. It's introduced by commit 4062f1a4c030 ("kconfig: use long options in conf") by Sam Ravnborg. Apparently that thing is totally buggy, and doesn't just change the option names, but actively breaks them. The old behaviour (from years ago) were reintroduced by accident. Fix this so we are back to the version that are silent if there is nothing to ask about.

Consider following example: config M def_bool y option modules choice prompt "choice list" config A tristate "a" config B tristate "b" endchoice With a defconfig like this: CONFIG_M=y CONFIG_A=y The resulting configuration would have CONFIG_A=m which was unexpected. The problem was not not all choice values were set and thus kconfig calculated a wrong value. The fix is to set all choice values when we read a defconfig files. conf_set_all_new_symbols() is refactored such that random choice values are now handled by a dedicated function. And new choice values are set by set_all_choice_values(). This was not the minimal fix, but the fix that resulted in the most readable code.
