Which devices can be changed/added/removed without impact? Are interrupts correctly mapped? - prep firmware (OHW) has support only for IDE drives (no SCSI). Booting from IDE has been broken approximatively 3 years ago, and nobody = complained. - OHW is limited on IDE boot to a specific set of OS loaders. These operating systems are of the 2004 time frame. - OHW can use -kernel. Linux kernel freezes a long time after PS/2 mouse detection, and then screen becomes garbage. This was already broken in QEMU v2.7, 2 years ago, and nobody complained. On the other side: - 40p is a real machine, so emulation can be checked against hardware specifications - OpenBIOS has support for SCSI block devices, including 40p LSI adapter - OpenBIOS can start mostly all Linux kernels (including recent ones) and recent operating system (like NetBSD 7.1.2) Signed-off-by: Herv=C3=A9 Poussineau [dwg: Drop prep from boot-serial test to avoid deprecation warnings] Signed-off-by: David Gibson --- hw/ppc/prep.c | 1 + tests/boot-serial-test.c | 2 -- 2 files changed, 1 insertion(+), 2 deletions(-) diff --git a/hw/ppc/prep.c b/hw/ppc/prep.c index b26138e5c4..83083e4f1b 100644 --- a/hw/ppc/prep.c +++ b/hw/ppc/prep.c @@ -587,6 +587,7 @@ static void ppc_prep_init(MachineState *machine) =20 static void prep_machine_init(MachineClass *mc) { + mc->deprecation_reason =3D "use 40p machine type instead"; mc->desc =3D "PowerPC PREP platform"; mc->init =3D ppc_prep_init; mc->block_default_type =3D IF_IDE; diff --git a/tests/boot-serial-test.c b/tests/boot-serial-test.c index fca5f2f5da..f123b15e3e 100644 --- a/tests/boot-serial-test.c +++ b/tests/boot-serial-test.c @@ -75,13 +75,11 @@ typedef struct testdef { static testdef_t tests[] =3D { { "alpha", "clipper", "", "PCI:" }, { "ppc", "ppce500", "", "U-Boot" }, - { "ppc", "prep", "-m 96", "Memory size: 96 MB" }, { "ppc", "40p", "-boot d", "Booting from device d" }, { "ppc", "g3beige", "", "PowerPC,750" }, { "ppc", "mac99", "", "PowerPC,G4" }, { "ppc", "sam460ex", "-m 256", "DRAM: 256 MiB" }, { "ppc64", "ppce500", "", "U-Boot" }, - { "ppc64", "prep", "-boot e", "Booting from device e" }, { "ppc64", "40p", "-m 192", "Memory size: 192 MB" }, { "ppc64", "mac99", "", "PowerPC,970FX" }, { "ppc64", "pseries", "", "Open Firmware" }, --=20 2.17.1
