From: Leonid Bloch <leonid.bl...@ravellosystems.com> These registers appear in Intel's specs, but were not implemented. These registers are now implemented trivially, i.e. they are initiated with zero values, and if they are RW, they can be written or read by the driver, or read only if they are R (essentially retaining their zero values). For these registers no other procedures are performed.
For the trivially implemented Diagnostic registers, a debug warning is produced on read/write attempts. PLEASE NOTE: these registers will not be active, nor will migrate, until a compatibility flag will be set (in a later patch in this series). The registers implemented here are: Transmit: RW: AIT Management: RW: WUC WUS IPAV IP6AT* IP4AT* FFLT* WUPM* FFMT* FFVT* Diagnostic: RW: RDFH RDFT RDFHS RDFTS RDFPC PBM* TDFH TDFT TDFHS TDFTS TDFPC Statistic: RW: FCRUC R: RNBC TSCTFC MGTPRC MGTPDC MGTPTC RFC RJC SCC ECOL LATECOL MCC COLC DC TNCRS SEC CEXTERR RLEC XONRXC XONTXC XOFFRXC XOFFTXC Signed-off-by: Leonid Bloch <leonid.bl...@ravellosystems.com> Signed-off-by: Dmitry Fleytman <dmitry.fleyt...@ravellosystems.com> Signed-off-by: Jason Wang <jasow...@redhat.com> --- hw/net/e1000.c | 97 +++++++++++++++++++++++++++++++++++++++++++++++++++-- hw/net/e1000_regs.h | 6 ++++ 2 files changed, 100 insertions(+), 3 deletions(-) diff --git a/hw/net/e1000.c b/hw/net/e1000.c index e079f25..767490c 100644 --- a/hw/net/e1000.c +++ b/hw/net/e1000.c @@ -172,7 +172,17 @@ enum { defreg(TPR), defreg(TPT), defreg(TXDCTL), defreg(WUFC), defreg(RA), defreg(MTA), defreg(CRCERRS), defreg(VFTA), defreg(VET), defreg(RDTR), defreg(RADV), defreg(TADV), - defreg(ITR), + defreg(ITR), defreg(FCRUC), defreg(TDFH), defreg(TDFT), + defreg(TDFHS), defreg(TDFTS), defreg(TDFPC), defreg(RDFH), + defreg(RDFT), defreg(RDFHS), defreg(RDFTS), defreg(RDFPC), + defreg(IPAV), defreg(WUC), defreg(WUS), defreg(AIT), + defreg(IP6AT), defreg(IP4AT), defreg(FFLT), defreg(FFMT), + defreg(FFVT), defreg(WUPM), defreg(PBM), defreg(SCC), + defreg(ECOL), defreg(MCC), defreg(LATECOL), defreg(COLC), + defreg(DC), defreg(TNCRS), defreg(SEC), defreg(CEXTERR), + defreg(RLEC), defreg(XONRXC), defreg(XONTXC), defreg(XOFFRXC), + defreg(XOFFTXC), defreg(RFC), defreg(RJC), defreg(RNBC), + defreg(TSCTFC), defreg(MGTPRC), defreg(MGTPDC), defreg(MGTPTC) }; static void @@ -1122,6 +1132,30 @@ mac_readreg(E1000State *s, int index) } static uint32_t +mac_low4_read(E1000State *s, int index) +{ + return s->mac_reg[index] & 0xf; +} + +static uint32_t +mac_low11_read(E1000State *s, int index) +{ + return s->mac_reg[index] & 0x7ff; +} + +static uint32_t +mac_low13_read(E1000State *s, int index) +{ + return s->mac_reg[index] & 0x1fff; +} + +static uint32_t +mac_low16_read(E1000State *s, int index) +{ + return s->mac_reg[index] & 0xffff; +} + +static uint32_t mac_icr_read(E1000State *s, int index) { uint32_t ret = s->mac_reg[ICR]; @@ -1223,18 +1257,37 @@ static uint32_t (*macreg_readops[])(E1000State *, int) = { getreg(RDH), getreg(RDT), getreg(VET), getreg(ICS), getreg(TDBAL), getreg(TDBAH), getreg(RDBAH), getreg(RDBAL), getreg(TDLEN), getreg(RDLEN), getreg(RDTR), getreg(RADV), - getreg(TADV), getreg(ITR), + getreg(TADV), getreg(ITR), getreg(FCRUC), getreg(IPAV), + getreg(WUC), getreg(WUS), getreg(SCC), getreg(ECOL), + getreg(MCC), getreg(LATECOL), getreg(COLC), getreg(DC), + getreg(TNCRS), getreg(SEC), getreg(CEXTERR), getreg(RLEC), + getreg(XONRXC), getreg(XONTXC), getreg(XOFFRXC), getreg(XOFFTXC), + getreg(RFC), getreg(RJC), getreg(RNBC), getreg(TSCTFC), + getreg(MGTPRC), getreg(MGTPDC), getreg(MGTPTC), [TOTH] = mac_read_clr8, [TORH] = mac_read_clr8, [GPRC] = mac_read_clr4, [GPTC] = mac_read_clr4, [TPT] = mac_read_clr4, [TPR] = mac_read_clr4, [ICR] = mac_icr_read, [EECD] = get_eecd, [EERD] = flash_eerd_read, + [RDFH] = mac_low13_read, [RDFT] = mac_low13_read, + [RDFHS] = mac_low13_read, [RDFTS] = mac_low13_read, + [RDFPC] = mac_low13_read, + [TDFH] = mac_low11_read, [TDFT] = mac_low11_read, + [TDFHS] = mac_low13_read, [TDFTS] = mac_low13_read, + [TDFPC] = mac_low13_read, + [AIT] = mac_low16_read, [CRCERRS ...
