From c9c1a064579c51d0133803895da1b7a971191f9a Mon Sep 17 00:00:00 2001 From: ths Date: Fri, 1 Jun 2007 14:58:56 +0000 Subject: [PATCH] Add support for 5Kc/5Kf/20Kc, based on a patch by Aurelien Jarno. Note that the F64 flag isn't usable on any of those (and the R4000), so all our 64bit FPU goodness goes out of the window until a shadow capability flag is implemented. :-( git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@2910 c046a42c-6fe2-441c-8c8c-71466251a162 --- hw/mips_malta.c | 2 +- target-mips/translate_init.c | 52 ++++++++++++++++++++++++++++++++++-- 2 files changed, 51 insertions(+), 3 deletions(-) diff --git a/hw/mips_malta.c b/hw/mips_malta.c index 359238d2b9..1164df1a91 100644 --- a/hw/mips_malta.c +++ b/hw/mips_malta.c @@ -784,7 +784,7 @@ void mips_malta_init (int ram_size, int vga_ram_size, int boot_device, /* init CPUs */ if (cpu_model == NULL) { #ifdef TARGET_MIPS64 - cpu_model = "R4000"; + cpu_model = "20Kc"; #else cpu_model = "24Kf"; #endif diff --git a/target-mips/translate_init.c b/target-mips/translate_init.c index ac62fad605..d793c9a70c 100644 --- a/target-mips/translate_init.c +++ b/target-mips/translate_init.c @@ -146,9 +146,57 @@ static mips_def_t mips_defs[] = .SYNCI_Step = 16, .CCRes = 2, .Status_rw_bitmask = 0x3678FFFF, - .CP1_fcr0 = (1 << FCR0_F64) | (1 << FCR0_L) | (1 << FCR0_W) | + /* XXX: The R4000 has a full 64bit FPU doesn't use the fcr0 bits. */ + .CP1_fcr0 = (0x5 << FCR0_PRID) | (0x0 << FCR0_REV), + }, + { + .name = "5Kc", + .CP0_PRid = 0x00018100, + .CP0_Config0 = MIPS_CONFIG0 | (0x2 << CP0C0_AT), + .CP0_Config1 = MIPS_CONFIG1 | (31 << CP0C1_MMU) | + (1 << CP0C1_IS) | (4 << CP0C1_IL) | (1 << CP0C1_IA) | + (1 << CP0C1_DS) | (4 << CP0C1_DL) | (1 << CP0C1_DA) | + (1 << CP0C1_PC) | (1 << CP0C1_WR) | (1 << CP0C1_EP), + .CP0_Config2 = MIPS_CONFIG2, + .CP0_Config3 = MIPS_CONFIG3, + .SYNCI_Step = 32, + .CCRes = 2, + .Status_rw_bitmask = 0x3278FFFF, + }, + { + .name = "5Kf", + .CP0_PRid = 0x00018100, + .CP0_Config0 = MIPS_CONFIG0 | (0x2 << CP0C0_AT), + .CP0_Config1 = MIPS_CONFIG1 | (1 << CP0C1_FP) | (31 << CP0C1_MMU) | + (1 << CP0C1_IS) | (4 << CP0C1_IL) | (1 << CP0C1_IA) | + (1 << CP0C1_DS) | (4 << CP0C1_DL) | (1 << CP0C1_DA) | + (1 << CP0C1_PC) | (1 << CP0C1_WR) | (1 << CP0C1_EP), + .CP0_Config2 = MIPS_CONFIG2, + .CP0_Config3 = MIPS_CONFIG3, + .SYNCI_Step = 32, + .CCRes = 2, + .Status_rw_bitmask = 0x3678FFFF, + /* XXX: The 5Kf has F64 / L / W but doesn't use the fcr0 bits. */ + .CP1_fcr0 = (1 << FCR0_D) | (1 << FCR0_S) | + (0x81 << FCR0_PRID) | (0x0 << FCR0_REV), + }, + { + .name = "20Kc", + .CP0_PRid = 0x00018200, + .CP0_Config0 = MIPS_CONFIG0 | (0x2 << CP0C0_AT) | (1 << CP0C0_VI), + .CP0_Config1 = MIPS_CONFIG1 | (1 << CP0C1_FP) | (47 << CP0C1_MMU) | + (2 << CP0C1_IS) | (4 << CP0C1_IL) | (3 << CP0C1_IA) | + (2 << CP0C1_DS) | (4 << CP0C1_DL) | (3 << CP0C1_DA) | + (1 << CP0C1_PC) | (1 << CP0C1_WR) | (1 << CP0C1_EP), + .CP0_Config2 = MIPS_CONFIG2, + .CP0_Config3 = MIPS_CONFIG3, + .SYNCI_Step = 32, + .CCRes = 2, + .Status_rw_bitmask = 0x36FBFFFF, + /* XXX: The 20Kc has F64 / L / W but doesn't use the fcr0 bits. */ + .CP1_fcr0 = (1 << FCR0_3D) | (1 << FCR0_PS) | (1 << FCR0_D) | (1 << FCR0_S) | - (0x5 << FCR0_PRID) | (0x0 << FCR0_REV), + (0x82 << FCR0_PRID) | (0x0 << FCR0_REV), }, #endif }; -- 2.34.1
