2019-01-11avoid TABs in files that only contain a fewPaolo Bonzini
Most files that have TABs only contain a handful of them. Change them to spaces so that we don't confuse people. disas, standard-headers, linux-headers and libdecnumber are imported from other projects and probably should be exempted from the check. Outside those, after this patch the following files still contain both 8-space and TAB sequences at the beginning of the line. Many of them have a majority of TABs, or were initially committed with all tabs. bsd-user/i386/target_syscall.h bsd-user/x86_64/target_syscall.h crypto/aes.c hw/audio/fmopl.c hw/audio/fmopl.h hw/block/tc58128.c hw/display/cirrus_vga.c hw/display/xenfb.c hw/dma/etraxfs_dma.c hw/intc/sh_intc.c hw/misc/mst_fpga.c hw/net/pcnet.c hw/sh4/sh7750.c hw/timer/m48t59.c hw/timer/sh_timer.c include/crypto/aes.h include/disas/bfd.h include/hw/sh4/sh.h libdecnumber/decNumber.c linux-headers/asm-generic/unistd.h linux-headers/linux/kvm.h linux-user/alpha/target_syscall.h linux-user/arm/nwfpe/double_cpdo.c linux-user/arm/nwfpe/fpa11_cpdt.c linux-user/arm/nwfpe/fpa11_cprt.c linux-user/arm/nwfpe/fpa11.h linux-user/flat.h linux-user/flatload.c linux-user/i386/target_syscall.h linux-user/ppc/target_syscall.h linux-user/sparc/target_syscall.h linux-user/syscall.c linux-user/syscall_defs.h linux-user/x86_64/target_syscall.h slirp/cksum.c slirp/if.c slirp/ip.h slirp/ip_icmp.c slirp/ip_icmp.h slirp/ip_input.c slirp/ip_output.c slirp/mbuf.c slirp/misc.c slirp/sbuf.c slirp/socket.c slirp/socket.h slirp/tcp_input.c slirp/tcpip.h slirp/tcp_output.c slirp/tcp_subr.c slirp/tcp_timer.c slirp/tftp.c slirp/udp.c slirp/udp.h target/cris/cpu.h target/cris/mmu.c target/cris/op_helper.c target/sh4/helper.c target/sh4/op_helper.c target/sh4/translate.c tcg/sparc/tcg-target.inc.c tests/tcg/cris/check_addo.c tests/tcg/cris/check_moveq.c tests/tcg/cris/check_swap.c tests/tcg/multiarch/test-mmap.c ui/vnc-enc-hextile-template.h ui/vnc-enc-zywrle.h util/envlist.c util/readline.c The following have only TABs: bsd-user/i386/target_signal.h bsd-user/sparc64/target_signal.h bsd-user/sparc64/target_syscall.h bsd-user/sparc/target_signal.h bsd-user/sparc/target_syscall.h bsd-user/x86_64/target_signal.h crypto/desrfb.c hw/audio/intel-hda-defs.h hw/core/uboot_image.h hw/sh4/sh7750_regnames.c hw/sh4/sh7750_regs.h include/hw/cris/etraxfs_dma.h linux-user/alpha/termbits.h linux-user/arm/nwfpe/fpopcode.h linux-user/arm/nwfpe/fpsr.h linux-user/arm/syscall_nr.h linux-user/arm/target_signal.h linux-user/cris/target_signal.h linux-user/i386/target_signal.h linux-user/linux_loop.h linux-user/m68k/target_signal.h linux-user/microblaze/target_signal.h linux-user/mips64/target_signal.h linux-user/mips/target_signal.h linux-user/mips/target_syscall.h linux-user/mips/termbits.h linux-user/ppc/target_signal.h linux-user/sh4/target_signal.h linux-user/sh4/termbits.h linux-user/sparc64/target_syscall.h linux-user/sparc/target_signal.h linux-user/x86_64/target_signal.h linux-user/x86_64/termbits.h pc-bios/optionrom/optionrom.h slirp/mbuf.h slirp/misc.h slirp/sbuf.h slirp/tcp.h slirp/tcp_timer.h slirp/tcp_var.h target/i386/svm.h target/sparc/asi.h target/xtensa/core-dc232b/xtensa-modules.inc.c target/xtensa/core-dc233c/xtensa-modules.inc.c target/xtensa/core-de212/core-isa.h target/xtensa/core-de212/xtensa-modules.inc.c target/xtensa/core-fsf/xtensa-modules.inc.c target/xtensa/core-sample_controller/core-isa.h target/xtensa/core-sample_controller/xtensa-modules.inc.c target/xtensa/core-test_kc705_be/core-isa.h target/xtensa/core-test_kc705_be/xtensa-modules.inc.c tests/tcg/cris/check_abs.c tests/tcg/cris/check_addc.c tests/tcg/cris/check_addcm.c tests/tcg/cris/check_addoq.c tests/tcg/cris/check_bound.c tests/tcg/cris/check_ftag.c tests/tcg/cris/check_int64.c tests/tcg/cris/check_lz.c tests/tcg/cris/check_openpf5.c tests/tcg/cris/check_sigalrm.c tests/tcg/cris/crisutils.h tests/tcg/cris/sys.c tests/tcg/i386/test-i386-ssse3.c ui/vgafont.h Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Message-Id: <20181213223737.11793-3-pbonzini@redhat.com> Reviewed-by: Aleksandar Markovic <amarkovic@wavecomp.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Wainer dos Santos Moschetta <wainersm@redhat.com> Acked-by: Richard Henderson <richard.henderson@linaro.org> Acked-by: Eric Blake <eblake@redhat.com> Acked-by: David Gibson <david@gibson.dropbear.id.au> Reviewed-by: Stefan Markovic <smarkovic@wavecomp.com> Reviewed-by: Michael S.

2019-01-11qemu/queue.h: leave head structs anonymous unless necessaryPaolo Bonzini
Most list head structs need not be given a name. In most cases the name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV or reverse iteration, but this does not apply to lists of other kinds, and even for QTAILQ in practice this is only rarely needed. In addition, we will soon reimplement those macros completely so that they do not need a name for the head struct. So clean up everything, not giving a name except in the rare case where it is necessary. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Intel HAXM supports now 32-bit and 64-bit Linux hosts. This patch includes the corresponding userland changes. Since the Darwin userland backend is POSIX-compliant, the hax-darwin.{c,h} files have been renamed to hax-posix.{c,h}. This prefix is consistent with the naming used in the rest of QEMU.

2019-01-09target/ppc: move FP and VMX registers into aligned vsr register arrayMark Cave-Ayland
The VSX register array is a block of 64 128-bit registers where the first 32 registers consist of the existing 64-bit FP registers extended to 128-bit using new VSR registers, and the last 32 registers are the VMX 128-bit registers as show below: 64-bit 64-bit +--------------------+--------------------+ | FP0 | | VSR0 +--------------------+--------------------+ | FP1 | | VSR1 +--------------------+--------------------+ | ... | ... | ... +--------------------+--------------------+ | FP30 | | VSR30 +--------------------+--------------------+ | FP31 | | VSR31 +--------------------+--------------------+ | VMX0 | VSR32 +-----------------------------------------+ | VMX1 | VSR33 +-----------------------------------------+ | ... | ... +-----------------------------------------+ | VMX30 | VSR62 +-----------------------------------------+ | VMX31 | VSR63 +-----------------------------------------+ In order to allow for future conversion of VSX instructions to use TCG vector operations, recreate the same layout using an aligned version of the existing vsr register array. Since the old fpr and avr register arrays are removed, the existing callers must also be updated to use the correct offset in the vsr register array. This also includes switching the relevant VMState fields over to using subarrays to make sure that migration is preserved.

Since the VSX registers are actually a superset of the VMX registers then they can be represented by the same type. Merge ppc_avr_t into ppc_vsr_t and change ppc_avr_t to be a simple typedef alias. Note that due to a difference in the naming of the float32 member between ppc_avr_t and ppc_vsr_t, references to the ppc_avr_t f member must be replaced with f32 instead.

Add translation handlers for four logic MXU instructions. It should be noted that there is an error in MXU documentation (dated June 2017) regarding opcodes for this group of instructions. This was confirmed by running tests on hardware, and also by looking up other related public source trees (binutils, Android NDK). In initial MXU patches to QEMU, opcodes for MXU logic instructions were created to be in accordance with the MXU documentation, therefore the error from was propagated. This patch corrects that, changing the involved code. Besides that, as MXU was designed and implemented only for 32-bit CPUs, corresponding preprosessor conditions were added around MXU code, which allows more flexible implementation of MXU handlers.

2018-12-21target/ppc: tcg: Implement addex instructionSuraj Jitindar Singh
Implement the addex instruction introduced in ISA V3.00 in qemu tcg. The add extended using alternate carry bit (addex) instruction performs the same operation as the add extended (adde) instruction, but using the overflow (ov) field in the fixed point exception register (xer) as the carry in and out instead of the carry (ca) field. The instruction has a Z23-form, not an XO form, as follows: ------------------------------------------------------------------ | 31 | RT | RA | RB | CY | 170 | 0 | ------------------------------------------------------------------ 0 6 11 16 21 23 31 32 However since the only valid form of the instruction defined so far is CY = 0, we can treat this like an XO form instruction. There is no dot form (addex.) of the instruction and the summary overflow (so) bit in the xer is not modified by this instruction. For simplicity we reuse the gen_op_arith_add function and add a function argument to specify where the carry in input should come from and the carry out output be stored (note must be the same location).

2018-12-21target/ppc: Remove silly GETFIELD/SETFIELD/MASK_TO_LSH macrosDavid Gibson
The (only) obvious use for these macros is constructing and parsing guest visible register fields. But the way they're constructed, they're only valid when used on a *host* long, whose size shouldn't be visible to the guest at all. They also have no current users, so just get rid of them.

2018-12-20target/riscv/pmp.c: Fix pmp_decode_napot()Anup Patel
Currently, start and end address of a PMP region are not decoded correctly by pmp_decode_napot(). Let's say we have a 128KB PMP region with base address as 0x80000000. Now, the PMPADDRx CSR value for this region will be 0x20003fff. The current pmp_decode_napot() implementation will decode PMPADDRx CSR as t1=14, base=0x100000000, and range=0x1ffff whereas it should have decoded PMPADDRx CSR as t1=14, base=0x80000000, and range=0x1fff. This patch fixes the base value decoding in pmp_decode_napot() when PMPADDRx CSR is not -1 (i.e. 0xffffffffffffffff).

2018-12-14target/arm: Create timers in realize, not initPeter Maydell
The timer_new() function allocates memory; this means that if we call it in the CPU's init method we would need to provide an instance_finalize method to free it. Defer the timer creation to the realize function instead. This fixes a memory leak spotted by clang LeakSanitizer when a CPU object is created for introspection.

2018-12-14target/arm: Free name string in ARMCPRegInfo hashtable entriesPeter Maydell
When we add a new entry to the ARMCPRegInfo hash table in add_cpreg_to_hashtable(), we allocate memory for tehe ARMCPRegInfo struct itself, and we also g_strdup() the name string. So the hashtable's value destructor function must free the name string as well as the struct. Spotted by clang's leak sanitizer. The leak here is a small one-off leak at startup, because we don't support CPU hotplug, and so the only time when we destroy hash table entries is for the case where ARM_CP_OVERRIDE means we register a wildcard entry and then override it later.
