2024-12-15bios_emulator: fix incorrect printing of address in "jump near immediate"Yuri Zaporozhets
In the x86emuOp_jump_call_near_IMM() function the target address is printed incorrectly when jumping backwards. For example instead of "jmp 0xe8bc" the string "jmp ffffe8bc" is printed. That's because of the following macro: DECODE_PRINTF2("%04x\n", ip); while it should be DECODE_PRINTF2("%04x\n", (u16)ip); Signed-off-by: Yuri Zaporozhets <yuriz@qrv-systems.net>
2024-12-15bios_emulator: fix incorrect printing of address in "call near immediate"Yuri Zaporozhets
In the x86emuOp_call_near_IMM() function the address of CALL is printed incorrectly when jumping backwards. For example, the correct disassemble of the bytes below would be: 0000E8DE E8DBFF call 0xe8bc (verified by ndisasm). But instead the address is printed as "ffffe8bc". That's because of the following macro: DECODE_PRINTF2("%04x\n", ip); while it should be DECODE_PRINTF2("%04x\n", (u16)ip); Signed-off-by: Yuri Zaporozhets <yuriz@qrv-systems.net>
2024-05-20Restore patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"Tom Rini
As part of bringing the master branch back in to next, we need to allow for all of these changes to exist here. Reported-by: Jonas Karlman <jonas@kwiboo.se> Signed-off-by: Tom Rini <trini@konsulko.com>
2024-05-19Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""Tom Rini
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

As it turns out this is a normal condition, so suppress the error. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-11-25bios_emulator: Always print errors when opcode decode failsSimon Glass
This is a rare event and should not happen. When it does it is confusing to work out why. At least we should print a message. Adjust the emulator to always print decode errors to the console. Signed-off-by: Simon Glass <sjg@chromium.org>
2014-11-25bios_emulator: Add an option to enable debuggingSimon Glass
At present there are DEBUG options spread around the place. If you enable one and not another you can end up with an emulator that does not work, since each file can have a different view of what the registers look like. To fix this, create a global CONFIG_X86EMU_DEBUG option that keeps everything consistent. Signed-off-by: Simon Glass <sjg@chromium.org>
