From 5706b0064d6a78c32bf46f18910bc4e10dde2687 Mon Sep 17 00:00:00 2001 From: Chalapathi V Date: Tue, 23 Jan 2024 16:37:02 +1000 Subject: hw/ppc: Add N1 chiplet model MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The N1 chiplet handle the high speed i/o traffic over PCIe and others. The N1 chiplet consists of PowerBus Fabric controller, nest Memory Management Unit, chiplet control unit and more. This commit creates a N1 chiplet model and initialize and realize the pervasive chiplet model where chiplet control registers are implemented. This commit also implement the read/write method for the powerbus scom registers Reviewed-by: Cédric Le Goater Signed-off-by: Chalapathi V Signed-off-by: Nicholas Piggin --- include/hw/ppc/pnv_n1_chiplet.h | 32 ++++++++++++++++++++++++++++++++ include/hw/ppc/pnv_xscom.h | 6 ++++++ 2 files changed, 38 insertions(+) create mode 100644 include/hw/ppc/pnv_n1_chiplet.h (limited to 'include') diff --git a/include/hw/ppc/pnv_n1_chiplet.h b/include/hw/ppc/pnv_n1_chiplet.h new file mode 100644 index 0000000..a7ad039 --- /dev/null +++ b/include/hw/ppc/pnv_n1_chiplet.h @@ -0,0 +1,32 @@ +/* + * QEMU PowerPC N1 chiplet model + * + * Copyright (c) 2023, IBM Corporation. + * + * SPDX-License-Identifier: GPL-2.0-or-later + */ + +#ifndef PPC_PNV_N1_CHIPLET_H +#define PPC_PNV_N1_CHIPLET_H + +#include "hw/ppc/pnv_nest_pervasive.h" + +#define TYPE_PNV_N1_CHIPLET "pnv-N1-chiplet" +#define PNV_N1_CHIPLET(obj) OBJECT_CHECK(PnvN1Chiplet, (obj), TYPE_PNV_N1_CHIPLET) + +typedef struct PnvPbScom { + uint64_t mode; + uint64_t hp_mode2_curr; +} PnvPbScom; + +typedef struct PnvN1Chiplet { + DeviceState parent; + MemoryRegion xscom_pb_eq_mr; + MemoryRegion xscom_pb_es_mr; + PnvNestChipletPervasive nest_pervasive; /* common pervasive chiplet unit */ +#define PNV_PB_SCOM_EQ_SIZE 8 + PnvPbScom eq[PNV_PB_SCOM_EQ_SIZE]; +#define PNV_PB_SCOM_ES_SIZE 4 + PnvPbScom es[PNV_PB_SCOM_ES_SIZE]; +} PnvN1Chiplet; +#endif /*PPC_PNV_N1_CHIPLET_H */ diff --git a/include/hw/ppc/pnv_xscom.h b/include/hw/ppc/pnv_xscom.h index 3e15706..535ae1d 100644 --- a/include/hw/ppc/pnv_xscom.h +++ b/include/hw/ppc/pnv_xscom.h @@ -173,6 +173,12 @@ struct PnvXScomInterfaceClass { #define PNV10_XSCOM_N1_CHIPLET_CTRL_REGS_BASE 0x3000000 #define PNV10_XSCOM_CHIPLET_CTRL_REGS_SIZE 0x400 +#define PNV10_XSCOM_N1_PB_SCOM_EQ_BASE 0x3011000 +#define PNV10_XSCOM_N1_PB_SCOM_EQ_SIZE 0x200 + +#define PNV10_XSCOM_N1_PB_SCOM_ES_BASE 0x3011300 +#define PNV10_XSCOM_N1_PB_SCOM_ES_SIZE 0x100 + #define PNV10_XSCOM_PEC_NEST_BASE 0x3011800 /* index goes downwards ... */ #define PNV10_XSCOM_PEC_NEST_SIZE 0x100 -- cgit v1.1
