drm/i915/bios: Use hardcoded fp_timing size for generating LFP data pointers

2022-10-24T07:58:32Z

commit d3a7051841f0a4bcb1ee26a1b721c6150cc4c2b1 upstream. The current scheme for generating the LFP data table pointers (when the block including them is missing from the VBT) expects the 0xffff sequence to only appear in the fp_timing terminator entries. However some VBTs also have extra 0xffff sequences elsewhere in the LFP data. When looking for the terminators we may end up finding those extra sequeneces insted, which means we deduce the wrong size for the fp_timing table. The code then notices the inconsistent looking values and gives up on the generated data table pointers, preventing us from parsing the LFP data table entirely. Let's give up on the "search for the terminators" approach and instead just hardcode the expected size for the fp_timing table. We have enough sanity checks in place to make sure we shouldn't end up parsing total garbage even if that size should change in the future (although that seems unlikely as the fp_timing and dvo_timing tables have been declared obsolete as of VBT version 229).

commit 4e78d6023c15c6acce8fbe42e13027c460395522 upstream. Validate the LFP data block a bit hardwer by making sure the fp_timing terminators (0xffff) are where we expect them to be.

drm/i915: Rename block_size()/block_offset()

2022-10-24T07:58:32Z

commit 39b1bc4b5bcccac781267bb826b035fbb99c8b9d upstream. Give block_size()/block_offset() a "raw_" prefix since they both operate on the "raw" (as in not duplicated) BDB block contents. What actually spurred this was a conflict between intel_bios.c block_size() vs. block_size() from blkdev.h. That only happened to me on a custom tree where we somehow manage to include blkdev.h into intel_bios.c. But I think the rename makes sense anyway to clarify the purpose of these functions.

ext4: continue to expand file system when the target size doesn't reach

HID: uclogic: Add missing suffix for digitalizers

commit 0977fda0587cbc5403651ba169e264aa01e8a026 upstream. The Pen (0x02) application usage was changed to Digitalizer (0x01) in commit f7d8e387d9ae ("HID: uclogic: Switch to Digitizer usage for styluses"). However, a suffix was not selected for the new usage. Handle the digitalizer application usage in uclogic_input_configured() and add the required suffix.

lib/Kconfig.debug: Add check for non-constant .{s,u}leb128 support to DWARF5

2022-10-24T07:58:31Z

commit 0a6de78cff600cb991f2a1b7ed376935871796a0 upstream. When building with a RISC-V kernel with DWARF5 debug info using clang and the GNU assembler, several instances of the following error appear: /tmp/vgettimeofday-48aa35.s:2963: Error: non-constant .uleb128 is not supported Dumping the .s file reveals these .uleb128 directives come from .debug_loc and .debug_ranges: .Ldebug_loc0: .byte 4 # DW_LLE_offset_pair .uleb128 .Lfunc_begin0-.Lfunc_begin0 # starting offset .uleb128 .Ltmp1-.Lfunc_begin0 # ending offset .byte 1 # Loc expr size .byte 90 # DW_OP_reg10 .byte 0 # DW_LLE_end_of_list .Ldebug_ranges0: .byte 4 # DW_RLE_offset_pair .uleb128 .Ltmp6-.Lfunc_begin0 # starting offset .uleb128 .Ltmp27-.Lfunc_begin0 # ending offset .byte 4 # DW_RLE_offset_pair .uleb128 .Ltmp28-.Lfunc_begin0 # starting offset .uleb128 .Ltmp30-.Lfunc_begin0 # ending offset .byte 0 # DW_RLE_end_of_list There is an outstanding binutils issue to support a non-constant operand to .sleb128 and .uleb128 in GAS for RISC-V but there does not appear to be any movement on it, due to concerns over how it would work with linker relaxation. To avoid these build errors, prevent DWARF5 from being selected when using clang and an assembler that does not have support for these symbol deltas, which can be easily checked in Kconfig with as-instr plus the small test program from the dwz test suite from the binutils issue.

Kconfig.debug: add toolchain checks for DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT

2022-10-24T07:58:31Z

commit bb1435f3f575b5213eaf27434efa3971f51c01de upstream. CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT does not give explicit -gdwarf-* flag. The actual DWARF version is up to the toolchain. The combination of GCC and GAS works fine, and Clang with the integrated assembler is good too. The combination of Clang and GAS is tricky, but at least, the -g flag works for Clang <=13, which defaults to DWARF v4. Clang 14 switched its default to DWARF v5. Now, CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT has the same issue as addressed by commit 98cd6f521f10 ("Kconfig: allow explicit opt in to DWARF v5"). CONFIG_DEBUG_INFO_DWARF_TOOLCHAIN_DEFAULT=y for Clang >= 14 and GAS < 2.35 produces a ton of errors like follows: /tmp/main-c2741c.s: Assembler messages: /tmp/main-c2741c.s:109: Error: junk at end of line, first unrecognized character is `"' /tmp/main-c2741c.s:109: Error: file number less than one Add 'depends on' to check toolchains.

kbuild: Add skip_encoding_btf_enum64 option to pahole

2022-10-24T07:58:31Z

New pahole (version 1.24) generates by default new BTF_KIND_ENUM64 BTF tag, which is not supported by stable kernel. As a result the kernel with CONFIG_DEBUG_INFO_BTF option will fail to compile with following error: BTFIDS vmlinux FAILED: load BTF from vmlinux: Invalid argument New pahole provides --skip_encoding_btf_enum64 option to skip BTF_KIND_ENUM64 generation and produce BTF supported by stable kernel. Adding this option to scripts/pahole-flags.sh. This change does not have equivalent commit in linus tree, because linus tree has support for BTF_KIND_ENUM64 tag, so it does not need to be disabled.
