2022-09-27hw/riscv/sifive_e: Fix inheritance of SiFiveEStateBernhard Beschow1-1/+2
SiFiveEState inherits from SysBusDevice while it's TypeInfo claims it to inherit from TYPE_MACHINE. This is an inconsistency which can cause undefined behavior such as memory corruption. Change SiFiveEState to inherit from MachineState since it is registered as a machine.

2022-09-27target/riscv: Check the correct exception cause in vector GDB stubFrank Chang1-2/+2
After RISCVException enum is introduced, riscv_csrrw_debug() returns RISCV_EXCP_NONE to indicate there's no error. RISC-V vector GDB stub should check the result against RISCV_EXCP_NONE instead of value 0. Otherwise, 'E14' packet would be incorrectly reported for vector CSRs when using "info reg vector" GDB command.

2022-09-27hw/riscv: opentitan: Expose the resetvec as a SoC propertyAlistair Francis2-1/+9
On the OpenTitan hardware the resetvec is fixed at the start of ROM. In QEMU we don't run the ROM code and instead just jump to the next stage. This means we need to be a little more flexible about what the resetvec is. This patch allows us to set the resetvec from the command line with something like this: -global driver=riscv.lowrisc.ibex.soc,property=resetvec,value=0x20000400 This way as the next stage changes we can update the resetvec.

2022-09-27target/riscv: remove fixed numbering from GDB xml feature filesAndrew Burgess4-20/+4
The fixed register numbering in the various GDB feature files for RISC-V only exists because these files were originally copied from the GDB source tree. However, the fixed numbering only exists in the GDB source tree so that GDB, when it connects to a target that doesn't provide a target description, will use a specific numbering scheme. That numbering scheme is designed to be compatible with the first versions of QEMU (for RISC-V), that didn't send a target description, and relied on a fixed numbering scheme. Because of the way that QEMU manages its target descriptions, recording the number of registers in each feature, and just relying on GDB's numbering starting from 0, then I propose that we remove all the fixed numbering from the RISC-V feature xml files, and just rely on the standard numbering scheme. Plenty of other targets manage their xml files this way, e.g. ARM, AArch64, Loongarch, m68k, rx, and s390.

2022-09-27target/riscv: remove fflags, frm, and fcsr from riscv-*-fpu.xmlAndrew Burgess3-38/+2
While testing some changes to GDB's handling for the RISC-V registers fcsr, fflags, and frm, I spotted that QEMU includes these registers twice in the target description it sends to GDB, once in the fpu feature, and once in the csr feature. Right now things basically work OK, QEMU maps these registers onto two different register numbers, e.g. fcsr maps to both 68 and 73, and GDB can use either of these to access the register. However, GDB's target descriptions don't really work this way, each register should appear just once in a target description, mapping the register name onto the number GDB should use when accessing the register on the target. Duplicate register names actually result in duplicate registers on the GDB side, however, as the registers have the same name, the user can only access one of these registers. Currently GDB has a hack in place, specifically for RISC-V, to spot the duplicate copies of these three registers, and hide them from the user, ensuring the user only ever sees a single copy of each. In this commit I propose fixing this issue on the QEMU side, and in the process, simplify the fpu register handling a little. I think we should, remove fflags, frm, and fcsr from the two (32-bit and 64-bit) fpu feature xml files. These files will only contain the 32 core floating point register f0 to f31. The fflags, frm, and fcsr registers will continue to be advertised in the csr feature as they currently are. With that change made, I will simplify riscv_gdb_get_fpu and riscv_gdb_set_fpu, removing the extra handling for the 3 status registers.

2022-09-22hw/net/e1000e_core: Use definition to avoid dynamic stack allocationPhilippe Mathieu-Daudé1-3/+4
The compiler isn't clever enough to figure 'min_buf_size' is a constant, so help it by using a definitions instead.

2022-09-22io/channel-websock: Replace strlen(const_str) by sizeof(const_str) - 1Philippe Mathieu-Daudé1-1/+1
The combined_key[... QIO_CHANNEL_WEBSOCK_GUID_LEN ...] array in qio_channel_websock_handshake_send_res_ok() expands to a call to strlen(QIO_CHANNEL_WEBSOCK_GUID), and the compiler doesn't realize the string is const, so consider combined_key[] being a variable-length array. To remove the variable-length array, we provide it a hint to the compiler by using sizeof() - 1 instead of strlen(). Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com> Reviewed-by: Daniel P.

2022-09-22hw/net/lan9118: Signal TSFL_INT flag when TX FIFO reaches specified levelLucas Dietrich1-0/+8
The LAN9118 allows the guest to specify a level for both the TX and RX FIFOs at which an interrupt will be generated. We implement the RSFL_INT interrupt for the RX FIFO but are missing the handling of the equivalent TSFL_INT for the TX FIFO. Add the missing test to set the interrupt if the TX FIFO has exceeded the guest-specified level. This flag is required for Micrium lan911x ethernet driver to work.
