From: Alastair D'Silva <alast...@d-silva.org> Apologies for the large CC list, it's a heads up for those responsible for subsystems where a prototype change in generic code causes a change in those subsystems.
This series enhances hexdump. These improve the readability of the dumped data in certain situations (eg. wide terminals are available, many lines of empty bytes exist, etc). The default behaviour of hexdump is unchanged, however, the prototype for hex_dump_to_buffer() has changed, and print_hex_dump() has been renamed to print_hex_dump_ext(), with a wrapper replacing it for compatibility with existing code, which would have been too invasive to change. Hexdump selftests have be run & confirmed passed. Changelog: V4: - Add missing header (linux/bits.h) - Fix comment formatting - Create hex_dump_to_buffer_ext & make hex_dump_to_buffer a wrapper V3: - Fix inline documention - use BIT macros - use u32 rather than u64 for flags V2: - Fix failing selftests - Fix precedence bug in 'Replace ascii bool in hex_dump_to_buffer...' - Remove hardcoded new lengths & instead relax the checks in hex_dump_to_buffer, allocating the buffer from the heap instead of the stack. - Replace the skipping of lines of 0x00/0xff with skipping lines of repeated characters, announcing what has been skipped. - Add spaces as an optional N-group separator - Allow byte ordering to be maintained when HEXDUMP_RETAIN_BYTE_ORDERING is set. - Updated selftests to cover 'Relax rowsize checks' & 'Optionally retain byte ordering' Alastair D'Silva (7): lib/hexdump.c: Fix selftests lib/hexdump.c: Relax rowsize checks in hex_dump_to_buffer lib/hexdump.c: Optionally suppress lines of repeated bytes lib/hexdump.c: Replace ascii bool in hex_dump_to_buffer with flags lib/hexdump.c: Allow multiple groups to be separated by lines '|' lib/hexdump.c: Allow multiple groups to be separated by spaces lib/hexdump.c: Optionally retain byte ordering drivers/gpu/drm/i915/intel_engine_cs.c | 5 +- drivers/isdn/hardware/mISDN/mISDNisar.c | 10 +- drivers/mailbox/mailbox-test.c | 8 +- drivers/net/ethernet/amd/xgbe/xgbe-drv.c | 2 +- .../net/ethernet/synopsys/dwc-xlgmac-common.c | 2 +- drivers/net/wireless/ath/ath10k/debug.c | 7 +- .../net/wireless/intel/iwlegacy/3945-mac.c | 4 +- drivers/platform/chrome/wilco_ec/debugfs.c | 10 +- drivers/scsi/scsi_logging.c | 8 +- drivers/staging/fbtft/fbtft-core.c | 2 +- fs/seq_file.c | 6 +- include/linux/printk.h | 75 ++++- lib/hexdump.c | 267 +++++++++++++++--- lib/test_hexdump.c | 154 +++++++--- 14 files changed, 438 insertions(+), 122 deletions(-) -- 2.21.0 _______________________________________________ ath10k mailing list ath10k@lists.infradead.org http://lists.infradead.org/mailman/listinfo/ath10k
