+# kernel-srpm-macros
+
+The kernel-srpm-macros package
+
+This source package results in two "binary" packages, kernel-rpm-macros
+and kernel-srpm-macros. The role and locations of files is as follows:
+
+kernel-srpm-macros:
+
+/usr/lib/rpm/fileattrs/kmod.attr
+	For /lib/modules/XYZ/modules.builtin and .../MODULE.ko.XYZ
+	specifies a Lua script to generate kmod(MODULE.ko)
+	"Provides:" deps
+/usr/lib/rpm/macros.d/macros.kernel-srpm
+	Automatically included by all rpm invocations.
+	Defines %kernel_arches (try rpm --eval '%kernel_arches')
+		Question: what uses this macro? I didn't find any users.
+
+kernel-rpm-macros:
+
+/usr/lib/rpm/redhat/find-provides.ksyms
+	Runs from rpmbuild at the end of kernel builds and 3rd party module
+	builds, to extract
+	kernel(SYMBOL)=0xHASH "Provides:" deps from modules in kernel packages,
+	and ksym(SYMBOL)=0xHASH for 3rd party modules.
+	Takes input list of files on stdin.
+/usr/lib/rpm/fileattrs/provided_ksyms.attr
+	For newer rpmbuild with "internal dependency generators",
+	this file specifies that find-provides.ksyms should be run
+	only on .ko.XYZ files
+	(with "external dependency generators", the script needs to
+	filter out the files by itself).
+
+/usr/lib/rpm/redhat/find-requires.ksyms
+	?
+/usr/lib/rpm/fileattrs/required_ksyms.attr
+	For newer rpmbuild with "internal dependency generators",
+	this file specifies that find-requires.ksyms should be run
+	only on .ko.XYZ files, and not for /lib/modules/XYZ/kernel/*
+	(IOW: only for building 3rd-party modules)
+
+/usr/lib/rpm/redhat/find-provides.d/modalias.prov
+	Runs from rpmbuild at the end of kernel builds and 3rd party module
+	builds, to extract
+	modalias(pci:SOMETHING)=OPTIONALLY_VERSION "Provides:" deps from modules
+	in kernel and 3rd party modules packages.
+	Takes input list of files on stdin.
+		Question: what uses these deps?
+/usr/lib/rpm/fileattrs/modalias.attr
+	For newer rpmbuild with "internal dependency generators",
+	this file specifies that modalias.prov should be run
+	only on .ko.XYZ files
+
+/usr/lib/rpm/redhat/find-provides.d/firmware.prov
+	?
+
+/usr/lib/rpm/kabi.sh
+	Runs from rpmbuild at the end of kernel build to extract
+	kernel(SYMBOL)=0xHASH "Provides:" deps.
+/usr/lib/rpm/fileattrs/kabi.attr
+	For newer rpmbuild with "internal dependency generators",
+	this file specifies that kabi.sh should be run on
+	/boot/symvers-* and /lib/modules/XYZ/symvers.gz
+
+/usr/lib/rpm/macros.d/macros.kmp
+	Automatically included by all rpm invocations.
+	Defines a number of macros.
+
+/usr/lib/rpm/redhat/brp-kmod-restore-perms
+	?
+/usr/lib/rpm/redhat/brp-kmod-set-exec-bit
+	?
+
+/usr/lib/rpm/redhat/kmodtool
+	?
+/usr/lib/rpm/redhat/rpmsort
+	?
+/usr/lib/rpm/redhat/symset-table

-* Mon Jun 12 2023 Eugene Syromiatnikov <esyr@redhat.com> - 1.0-13
-- Handle symvers.xz in kabi.attr (#2209253).
-- Fix indirect __crc_* sumbols parsing in find-provides.ksyms
-  and find-requires.ksyms to avoid matching multiple sections
-  producing bogus duplicate provides for kmods that have both __kcrctab
-  and __kcrctab_gpl sections (#2115811, #2178935).
-- Call "readelf -R" on a correct section in find-requires.ksyms.
-- Rewrite section data extraction in find-provides.ksyms and find-requires.ksyms
-  to avoid garbage at the end of extracted sections, causing unnecessary awk
-  complaints (#2115811).
-- Perform section parsing inside the awk script in find-provides.ksyms
-  and find-requires.ksyms to avoid hitting command line argument limit
-  when handling large .rodata sections (#2178935).
