2011-04-04lm32: add Milkymist HPDMC supportMichael Walle3-0/+166
This patch adds support for the Milkymist's High Performance Dynamic Memory Controller. This is just a dumb model without any functionality. While the real hardware acts for example as a bridge between software and hardware for sending SDRAM commans, this model will only eat up these commands and always returns the expected hardware states, eg. PLL locked etc. Signed-off-by: Michael Walle <michael@walle.cc> Signed-off-by: Edgar E. Iglesias <edgar.iglesias@gmail.com>

Commit 6b331efb733a0f913ddc0b7762a1307dec304061 broke the s390 proxy version of virtio-serial by only taking its PCI brother into account. So let's adjust s390-virtio-serial the same way as its PCI counterpart, making it compile and work again.

2011-04-04s390x: fix KVM targetAlexander Graf1-1/+1
During Jan's rework of the generic KVM layer, he added some more error checks and actually aborted if something went wrong. Unfortunately, one of the s390 internal error codes slipped through, aborting the VM without needing to. This patch fixes booting of S390x virtual machines in KVM.

2011-04-04virtio: use generic name when possibleAlexander Graf4-4/+9
We have two different virtio buses: pci and s390. The abstraction path taken in qemu is to have generic aliases for each device type in the architecture specific qdev devices.

When the VM goes into stop state while there is a gdb frontend attached, it makes sense to inform gdb about this fact and at least a bit about the stop reason.

2011-04-03ioapic: when switches to level trigger mode, interrupts raised repeatedly.Isaku Yamahata1-0/+1
- the trigger mode is edge at first - During initializatoin, the interrupt is raised as edge which is masked. The corresponding bit of irr is set. - Then the mode is switched to level and it's unmasked. - the bit of irr is set, so the interrupt is raised repeatedly by ioapic_service(). - OS considers that the irq line is broken and falls back to polling mode. This patch fixes the issues. After raising edige, clear the bit of irr. > Bringing up interface eth0: > Determining IP information for eth0...irq 18: nobody cared (try booting with the "irqpoll" option) > Pid: 4126, comm: ip Not tainted 2.6.38-rc7 #1 > Call Trace: > <IRQ> [<ffffffff8105b009>] ? __report_bad_irq+0x38/0x87 > [<ffffffff8105b177>] ? note_interrupt+0x11f/0x188 > [<ffffffff8105bacf>] ? handle_fasteoi_irq+0xa7/0xd1 > [<ffffffff810046ff>] ? handle_irq+0x83/0x8c > [<ffffffff81003eb9>] ? do_IRQ+0x48/0xaf > [<ffffffff81300513>] ? ret_from_intr+0x0/0xe > [<ffffffff81031ab8>] ? __do_softirq+0x4f/0x114 > [<ffffffff81002d6c>] ? call_softirq+0x1c/0x28 > [<ffffffff81004647>] ? do_softirq+0x33/0x68 > [<ffffffff810316fb>] ? irq_exit+0x36/0x38 > [<ffffffff81015f2c>] ? smp_apic_timer_interrupt+0x88/0x96 > [<ffffffff81002853>] ? apic_timer_interrupt+0x13/0x20 > <EOI> [<ffffffff810177ed>] ? __ioapic_set_affinity+0x68/0x7c > [<ffffffff813000f0>] ? _raw_spin_unlock_irqrestore+0x8/0xa > [<ffffffff8105a84f>] ? __setup_irq+0x224/0x2cb > [<ffffffff8120e3c5>] ? e1000_intr+0x0/0x103 > [<ffffffff8105a9c7>] ? request_threaded_irq+0xd1/0x114 > [<ffffffff8120e396>] ? e1000_request_irq+0x34/0x63 > [<ffffffff8121237d>] ? e1000_open+0x81/0x11f > [<ffffffff8129097c>] ? call_netdevice_notifiers+0x45/0x4a > [<ffffffff81290d8d>] ? __dev_open+0x97/0xc4 > [<ffffffff8128e9c5>] ? __dev_change_flags+0xb9/0x13d > [<ffffffff81290cc1>] ? dev_change_flags+0x1c/0x51 > [<ffffffff812d0542>] ? devinet_ioctl+0x26e/0x594 > [<ffffffff812d174c>] ? inet_ioctl+0x92/0xaa > [<ffffffff81281d75>] ?

And we change the client to send it's own Init message regardless of receiving this one. Additional Init messages will be regarded as acceptable, the first one received after connection establishment is the determining one wrt capabilities.

2011-04-01pcnet: Fix sign extension: make ipxe work with >2G RAMMichael Brown1-15/+15
The problem is with definitions in hw/pcnet.c such as: #define CSR_CRDA(S) ((S)->csr[28] | ((S)->csr[29] << 16)) "(S)->csr[29]" is a uint16_t, but "(S)->csr[29] << 16" gets promoted to int, so the overall CSR_CRDA(s) is a (signed) int rather than a uint32_t. This then gets assigned to a uint64_t using target_phys_addr_t crda = CSR_CRDA(s); so when (S)->csr[29] has the high bit set, we end up with crda=0xffffffffxxxxxxxx.

2011-04-01target-arm: Fix VLD of single element to all lanesPeter Maydell1-25/+59
Fix several bugs in VLD of single element to all lanes: The "single element to all lanes" form of VLD1 differs from those for VLD2, VLD3 and VLD4 in that bit 5 indicates whether the loaded element should be written to one or two Dregs (rather than being a register stride). Handle this by special-casing VLD1 rather than trying to have one loop which deals with both VLD1 and 2/3/4. Handle VLD4.32 with 16 byte alignment specified, rather than UNDEFfing. UNDEF for the invalid size and alignment combinations. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2011-04-01get rid of private bitmap functions in block/sheepdog.c, use generic onesMichael Tokarev1-14/+1
qemu now has generic bitmap functions, so don't redefine them in sheepdog.c, use common header instead. A small cleanup. Here's only one function which is actually used in sheepdog and gets replaced with a generic one (simplified): - static inline int test_bit(int nr, const volatile unsigned long *addr) + static inline int test_bit(int nr, const unsigned long *addr) { - return ((1UL << (nr % BITS_PER_LONG)) & ((unsigned long*)addr)[nr / BITS_PER_LONG])) != 0; + return 1UL & (addr[nr / BITS_PER_LONG] >> (nr & (BITS_PER_LONG-1))); } The body is equivalent, but the argument is not: there's "volatile" in there. Why it is used for - I'm not sure. Signed-off-by: Michael Tokarev <mjt@tls.msk.ru> Acked-by: MORITA Kazutaka <morita.kazutaka@lab.ntt.co.jp> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

Load an optional QEMU icon file. If there is no icon file named qemu.bmp in QEMU's default search path, QEMU will run with the usual system default icon. A matching icon file will be loaded and used by X Windows managers or MS Windows while a QEMU instance is running. SDL requires icon files in 32x32x4 bmp format.

2011-04-01Add SLOF-based partition firmware for pSeries machine, allowing more boot ↵David Gibson7-5/+118
options Currently, the emulated pSeries machine requires the use of the -kernel parameter in order to explicitly load a guest kernel. This means booting from the virtual disk, cdrom or network is not possible. This patch addresses this limitation by inserting a within-partition firmware image (derived from the "SLOF" free Open Firmware project). If -kernel is not specified, qemu will now load the SLOF image, which has access to the qemu boot device list through the device tree, and can boot from any of the usual virtual devices. In order to support the new firmware, an extension to the emulated machine/hypervisor is necessary. Unlike Linux, which expects multi-CPU entry to be handled kexec() style, the SLOF firmware expects only one CPU to be active at entry, and to use a hypervisor RTAS method to enable the other CPUs one by one. This patch also implements this 'start-cpu' method, so that SLOF can start the secondary CPUs and marshal them into the kexec() holding pattern ready for entry into the guest OS. Linux should, and in the future might directly use the start-cpu method to enable initially disabled CPUs, but for now it does require kexec() entry.
