Currently, when QEMU fails to load images (kernel, BIOS, initrd) via load_image_targphys(), the error messages are not descriptive enough for users to understand why the loading failed. This series adds the ability to add Error information through the loader functions to provide more detailed error reporting.
v9: - Split Patch 2 from v8 into two patches. - Included RB from Aditya Gupta. v8: - Rebased on latest master. - Modified commit message for Patch 5. v7: - Dropped the patch [hw/ppc/spapr: Rename resize_hpt_err to errp]. already merged. Rebased on latest master. v6: - Pass error_fatal instead of errp where caller exits right after load_image_targphys() fails. - Include filename in error messages. v5: - Moved the patch which replaces open() with qemu_open() earlier in the series. - Incorporated minor changes in the error messages requested by Balaton. - Moved check for size zero in load_image_targphys_as() into it's separate patch. v4: - Reject empty files (`size == 0`) with an appropriate error. [1/5] - Populate error when `rom_add_file_fixed_as()` fails. [1/5] - Add missing check in hw/ppc/virtex_ml507.c [5/5] - Fixed checkpatch warnings [5/5] - Check errp for failures from load_image_targphys/load_image_targphys_as [3,5/5] - Remove unused variables [5/5] v3: - Use qemu_open() instead of open() in get_image_size() (danpb) - Remove redundant error_setg_file_open() call (danpb) - Use error_prepend()/error_reportf_err() to preserve underlying error details (danpb) [v8]: https://lore.kernel.org/all/[email protected] [v7]: https://lore.kernel.org/all/[email protected] [v6]: https://lore.kernel.org/qemu-devel/[email protected] [v5]: https://lore.kernel.org/all/[email protected] [v4]: https://lore.kernel.org/all/[email protected] [v3]: https://lore.kernel.org/all/[email protected] [v2]: https://lore.kernel.org/all/[email protected] [v1]: https://lore.kernel.org/all/[email protected] Vishal Chourasia (6): core/loader: Use qemu_open() instead of open() in get_image_size() core/loader: capture Error from load_image_targphys core/loader: split error handling in image loading functions core/loader: add check for zero size in load_image_targphys_as core: Pass errp to load_image_targphys_as() ppc: Pass error_fatal to load_image_targphys() hw/alpha/dp264.c | 4 ++-- hw/arm/armv7m.c | 2 +- hw/arm/boot.c | 5 +++-- hw/arm/digic_boards.c | 2 +- hw/arm/highbank.c | 3 ++- hw/arm/raspi.c | 2 +- hw/arm/vexpress.c | 2 +- hw/core/generic-loader.c | 8 +++++--- hw/core/guest-loader.c | 7 ++++--- hw/core/loader.c | 37 +++++++++++++++++++++++++++++-------- hw/hppa/machine.c | 5 +++-- hw/i386/multiboot.c | 2 +- hw/i386/x86-common.c | 4 ++-- hw/ipmi/ipmi_bmc_sim.c | 2 +- hw/loongarch/boot.c | 5 ++--- hw/m68k/an5206.c | 2 +- hw/m68k/mcf5208.c | 4 ++-- hw/m68k/next-cube.c | 2 +- hw/m68k/q800.c | 7 ++++--- hw/m68k/virt.c | 4 ++-- hw/microblaze/boot.c | 5 +++-- hw/mips/boston.c | 2 +- hw/mips/fuloong2e.c | 9 +++++---- hw/mips/jazz.c | 2 +- hw/mips/loongson3_virt.c | 10 ++++++---- hw/mips/malta.c | 9 +++++---- hw/nubus/nubus-device.c | 2 +- hw/openrisc/boot.c | 5 +++-- hw/pci/pci.c | 2 +- hw/ppc/amigaone.c | 13 ++----------- hw/ppc/e500.c | 20 ++++---------------- hw/ppc/mac_newworld.c | 19 ++++++------------- hw/ppc/mac_oldworld.c | 19 ++++++------------- hw/ppc/pegasos2.c | 10 +++------- hw/ppc/pnv.c | 27 ++++++--------------------- hw/ppc/ppc440_bamboo.c | 9 ++------- hw/ppc/prep.c | 19 ++++++------------- hw/ppc/sam460ex.c | 8 ++------ hw/ppc/spapr.c | 17 ++++------------- hw/ppc/virtex_ml507.c | 11 +++-------- hw/riscv/boot.c | 7 ++++--- hw/rx/rx-gdbsim.c | 2 +- hw/s390x/ipl.c | 8 +++++--- hw/sh4/r2d.c | 8 +++++--- hw/smbios/smbios.c | 2 +- hw/sparc/leon3.c | 4 ++-- hw/sparc/sun4m.c | 8 +++++--- hw/sparc64/sun4u.c | 7 ++++--- hw/xtensa/xtfpga.c | 3 ++- include/hw/loader.h | 8 +++++--- system/device_tree.c | 2 +- 51 files changed, 173 insertions(+), 213 deletions(-) -- 2.51.0
