Only the first memory # block maybe accessible in real mode. And, unlike the case with panic # kernel, no memory is set aside for regular kexec load. Another thing # to note is, the memory for crashkernel is reserved at an offset of # 128MB. So, when crashkernel memory is reserved, the memory ranges to # load kexec segments shrink further as the generic code only looks for # memblock free memory ranges and in all likelihood only a tiny bit of # memory from 0 to 128MB would be available to load kexec segments. # # With kdump being used by default in general, kexec file load is likely # to fail almost always. This can be fixed by changing the memory hole # lookup logic for regular kexec to use the same method as kdump. This # would mean that most kexec segments will overlap with crashkernel # memory region. That should still be ok as the pages, whose destination # address isn't available while loading, are placed in an intermediate # location till a flush to the actual destination address happens during # kexec boot sequence. # # Signed-off-by: Hari Bathini <hbathini@linux.ibm.com> # Tested-by: Pingfan Liu <piliu@redhat.com> # Reviewed-by: Thiago Jung Bauermann <bauerman@linux.ibm.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/159579242226.5790.13933486642004084417.stgit@hbathini # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 eaa567ccaf3a2a7b14ffa38af4bd09613aa1830f # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_tqm8548_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/tqm8548_defconfig # < make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_tqm8548_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_tqm8548_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 48 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_tqm8548_defconfig_powerpc-gcc4.9 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-4.9.4-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/drivers/mtd/nand/raw/fsl_upm.c: In function 'fun_wait_rnb': /kisskb/src/drivers/mtd/nand/raw/fsl_upm.c:65:20: warning: unused variable 'mtd' [-Wunused-variable] struct mtd_info *mtd = nand_to_mtd(&fun->chip); ^ INFO: Uncompressed kernel (size 0x53a9dc) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x52a278) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.8.0-rc2-32172-geaa567cca Created: Wed Jul 29 03:26:53 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2655740 Bytes = 2593.50 KiB = 2.53 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.8.0-rc2-32172-geaa567cca Created: Wed Jul 29 03:26:53 2020 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2686593 Bytes = 2623.63 KiB = 2.56 MiB Load Address: 00600000 Entry Point: 006002a4 Completed OK # rm -rf /kisskb/build/powerpc-next_85xx_tqm8548_defconfig_powerpc-gcc4.9 # Build took: 0:00:42.987370
