Implemented are: - RX and TX functionality - Perfect Frame Filtering - Big/Little Endian descriptor support - 93C46 EEPROM support - LXT970 PHY Not implemented, mostly because i had no OS using these functions: - Imperfect frame filtering - General Purpose Timer - Transmit automatic polling - Boot ROM support - SIA interface - Big/Little Endian data buffer conversion Successfully tested with the following Operating Systems: - MSDOS with Microsoft Network Client 3.0 and DEC ODI drivers - HPPA Linux - Windows XP - HP-UX Signed-off-by: Sven Schnelle --- MAINTAINERS | 6 + hw/net/Kconfig | 5 + hw/net/Makefile.objs | 1 + hw/net/trace-events | 14 + hw/net/tulip.c | 992 +++++++++++++++++++++++++++++++++++++++ hw/net/tulip.h | 265 +++++++++++ include/hw/pci/pci_ids.h | 1 + 7 files changed, 1284 insertions(+) create mode 100644 hw/net/tulip.c create mode 100644 hw/net/tulip.h diff --git a/MAINTAINERS b/MAINTAINERS index 250ce8e7a1..a12031c389 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -1638,6 +1638,12 @@ M: Stefan Weil S: Maintained F: hw/net/eepro100.c +tulip +M: Sven Schnelle +S: Maintained +F: hw/net/tulip.c +F: hw/net/tulip.h + Generic Loader M: Alistair Francis S: Maintained diff --git a/hw/net/Kconfig b/hw/net/Kconfig index 4ef86dc3a5..3856417d42 100644 --- a/hw/net/Kconfig +++ b/hw/net/Kconfig @@ -24,6 +24,11 @@ config PCNET_PCI config PCNET_COMMON bool +config TULIP + bool + default y if PCI_DEVICES + depends on PCI + config E1000_PCI bool default y if PCI_DEVICES diff --git a/hw/net/Makefile.objs b/hw/net/Makefile.objs index 9904273b06..7907d2c199 100644 --- a/hw/net/Makefile.objs +++ b/hw/net/Makefile.objs @@ -13,6 +13,7 @@ common-obj-$(CONFIG_E1000E_PCI_EXPRESS) += e1000e.o e1000e_core.o e1000x_common. common-obj-$(CONFIG_RTL8139_PCI) += rtl8139.o common-obj-$(CONFIG_VMXNET3_PCI) += net_tx_pkt.o net_rx_pkt.o common-obj-$(CONFIG_VMXNET3_PCI) += vmxnet3.o +common-obj-$(CONFIG_TULIP) += tulip.o common-obj-$(CONFIG_SMC91C111) += smc91c111.o common-obj-$(CONFIG_LAN9118) += lan9118.o diff --git a/hw/net/trace-events b/hw/net/trace-events index 58665655cc..e70f12bee1 100644 --- a/hw/net/trace-events +++ b/hw/net/trace-events @@ -367,3 +367,17 @@ virtio_net_announce_notify(void) "" virtio_net_announce_timer(int round) "%d" virtio_net_handle_announce(int round) "%d" virtio_net_post_load_device(void) + +# tulip.c +tulip_reg_write(uint64_t addr, const char *name, int size, uint64_t val) "addr 0x%02"PRIx64" (%s) size %d value 0x%08"PRIx64 +tulip_reg_read(uint64_t addr, const char *name, int size, uint64_t val) "addr 0x%02"PRIx64" (%s) size %d value 0x%08"PRIx64 +tulip_receive(const uint8_t *buf, size_t len) "buf %p size %zu" +tulip_descriptor(const char *prefix, uint32_t addr, uint32_t status, uint32_t control, uint32_t len1, uint32_t len2, uint32_t buf1, uint32_t buf2) "%s 0x%08x: status 0x%08x control 0x%03x len1 %4d len2 %4d buf1 0x%08x buf2 0x%08x" +tulip_rx_state(const char *state) "RX %s" +tulip_tx_state(const char *state) "TX %s" +tulip_irq(uint32_t mask, uint32_t en, const char *state) "mask 0x%08x ie 0x%08x %s" +tulip_mii_write(int phy, int reg, uint16_t data) "phy 0x%x reg 0x%x data 0x%04x" +tulip_mii_read(int phy, int reg, uint16_t data) "phy 0x%x, reg 0x%x data 0x%04x" +tulip_reset(void) "" +tulip_setup_frame(void) "" +tulip_setup_filter(int n, uint8_t a, uint8_t b, uint8_t c, uint8_t d, uint8_t e, uint8_t f) "%d: %02x:%02x:%02x:%02x:%02x:%02x" diff --git a/hw/net/tulip.c b/hw/net/tulip.c new file mode 100644 index 0000000000..a99b1b81c4 --- /dev/null +++ b/hw/net/tulip.c @@ -0,0 +1,992 @@ +/* + * QEMU TULIP Emulation + * + * Copyright (c) 2019 Sven Schnelle + * + * This work is licensed under the GNU GPL license version 2 or later. + */ + +#include "qemu/osdep.h" +#include "qemu/log.h" +#include "hw/irq.h" +#include "hw/pci/pci.h" +#include "hw/qdev-properties.h" +#include "hw/nvram/eeprom93xx.h" +#include "migration/vmstate.h" +#include "sysemu/sysemu.h" +#include "tulip.h" +#include "trace.h" +#include "net/eth.h" + +typedef struct TULIPState { + PCIDevice dev;
