2013-12-10acpi unit-test: verify signature and checksumMarcel Apfelbaum
Read all ACPI tables from guest - will be useful for further unit tests. Follow pointers between ACPI tables checking signature and format for correctness. Verify checksum for all tables. Signed-off-by: Marcel Apfelbaum <marcel.a@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2013-12-10smbios: Set system manufacturer, product & version by defaultMarkus Armbruster
Currently, we get SeaBIOS defaults: manufacturer Bochs, product Bochs, no version. Best SeaBIOS can do, but we can provide better defaults: manufacturer QEMU, product & version taken from QEMUMachine desc and name. Take care to do this only for new machine types, of course. Note: Michael Tsirkin doesn't trust us to keep values of QEMUMachine member product stable in the future. Use copies instead, and in a way that makes it obvious that they're guest ABI. Note that we can be trusted to keep values of member name, because that has always been ABI. Reviewed-by: Eduardo Habkost <ehabkost@redhat.com> Reviewed-by: Michael S.

2013-12-10exec: reduce L2_PAGE_SIZEMichael S. Tsirkin
With the single exception of ppc with 16M pages, we get the same number of levels with L2_PAGE_SIZE = 10 as with L2_PAGE_SIZE = 9. by doing this we reduce memory footprint of a single level in the node memory map by 2x without runtime overhead. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2013-12-10exec: make address spaces 64-bit widePaolo Bonzini
As an alternative to commit 818f86b (exec: limit system memory size, 2013-11-04) let's just make all address spaces 64-bit wide. This eliminates problems with phys_page_find ignoring bits above TARGET_PHYS_ADDR_SPACE_BITS and address_space_translate_internal consequently messing up the computations. In Luiz's reported crash, at startup gdb attempts to read from address 0xffffffffffffffe6 to 0xffffffffffffffff inclusive. The region it gets is the newly introduced master abort region, which is as big as the PCI address space (see pci_bus_init). Due to a typo that's only 2^63-1, not 2^64. But we get it anyway because phys_page_find ignores the upper bits of the physical address. In address_space_translate_internal then diff = int128_sub(section->mr->size, int128_make64(addr)); *plen = int128_get64(int128_min(diff, int128_make64(*plen))); diff becomes negative, and int128_get64 booms. The size of the PCI address space region should be fixed anyway. Reported-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Michael S.

2013-12-10exec: memory radix tree page level compressionMichael S. Tsirkin
At the moment, memory radix tree is already variable width, but it can only skip the low bits of address. This is efficient if we have huge memory regions but inefficient if we are only using a tiny portion of the address space. After we have built up the map, detect configurations where a single L2 entry is valid. We then speed up the lookup by skipping one or more levels. In case any levels were skipped, we might end up in a valid section instead of erroring out. We handle this by checking that the address is in range of the resulting section.

2013-12-10exec: extend skip field to 6 bit, page entry to 32 bitMichael S. Tsirkin

2013-12-10split definitions for exec.c and translate-all.c radix treesPaolo Bonzini
The exec.c and translate-all.c radix trees are quite different, and the exec.c one in particular is not limited to the CPU---it can be used also by devices that do DMA, and in that case the address space is not limited to TARGET_PHYS_ADDR_SPACE_BITS bits. We want to make exec.c's radix trees 64-bit wide. As a first step, stop sharing the constants between exec.c and translate-all.c. exec.c gets P_L2_* constants, translate-all.c gets V_L2_*, for consistency with the existing V_L1_* symbols. Though actually in the softmmu case translate-all.c is also indexed by physical addresses... This patch has no semantic change.

2013-12-10spapr_pci: s/INT64_MAX/UINT64_MAX/Michael S. Tsirkin
It doesn't make sense for a region to be INT64_MAX in size: memory core uses UINT64_MAX as a special value meaning "all 64 bit" this is what was meant here. While this should never affect the spapr system which at the moment always has < 63 bit size, this makes us hit all kind of corner case bugs with sub-pages, so users are probably better off if we just use UINT64_MAX instead.

2013-12-10qtest: split configuration of qtest accelerator and chardevPaolo Bonzini
qtest uses the icount infrastructure to implement a test-driven vm_clock. This however is not necessary when using -qtest as a "probe" together with a normal TCG-, KVM- or Xen-based virtual machine. Hence, split out the call to configure_icount into a new function that is called only for "-machine accel=qtest"; and disable those commands when running with an accelerator other than qtest. This also fixes an assertion failure with "qemu-system-x86_64 -machine accel=qtest" but no -qtest option. This is a valid case, albeit somewhat weird; nothing will happen in the VM but you'll still be able to interact with the monitor or the GUI. Now that qtest_init is not limited to an int(void) function, change global variables that are not used outside qtest_init to arguments. And finally, cleanup useless parts of include/sysemu/qtest.h. The file is not used at all for user-only emulation, and qtest is not available on Win32 due to its usage of sigwait. Reported-by: Michael S. Tsirkin <mst@redhat.com> Reviewed-by: Michael S.

2013-12-06vfio-pci: Fix Nvidia MSI ACK through 0x88000 quirkAlex Williamson
When MSI is enabled on Nvidia GeForce cards the driver seems to acknowledge the interrupt by writing a 0xff byte to the MSI capability ID register using the PCI config space mirror at offset 0x88000 from BAR0. Without this, the device will only fire a single interrupt. VFIO handles the PCI capability ID/next registers as virtual w/o write support, so any write through config space is currently dropped. Add a check for this and allow the write through the BAR window. The registers are read-only anyway. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

SMTP does not preserve newlines. This is normally not a problem if the email body uses DOS or UNIX newlines consistently. In 051.out we mix UNIX newlines with DOS newlines (since QEMU monitor output uses \r\n). This patch filters the QEMU monitor output so the golden master file uses UNIX newlines exclusively.

2013-12-06aio: make aio_poll(ctx, true) block with no fdsStefan Hajnoczi
This patch drops a special case where aio_poll(ctx, true) returns false instead of blocking if no file descriptors are waiting on I/O. Now it is possible to block in aio_poll() to wait for aio_notify(). This change eliminates busy waiting. bdrv_drain_all() used to rely on busy waiting to completed throttled I/O requests but this is no longer required so we can simplify aio_poll(). Note that aio_poll() still returns false when aio_notify() was used. In other words, stopping a blocking aio_poll() wait is not considered making progress. Adjust test-aio /aio/bh/callback-delete/one which assumed aio_poll(ctx, true) would immediately return false instead of blocking.

Since cc0681c45430a1f1a4c2d06e9499b7775afc9a18 ("block: Enable the new throttling code in the block layer.") bdrv_drain_all() no longer spins. The code used to look as follows: do { busy = qemu_aio_wait(); /* FIXME: We do not have timer support here, so this is effectively * a busy wait. */ QTAILQ_FOREACH(bs, &bdrv_states, list) { while (qemu_co_enter_next(&bs->throttled_reqs)) { busy = true; } } } while (busy); Note that throttle requests are kicked but I/O throttling limits are still in effect. The loop spins until the vm_clock time allows the request to make progress and complete. The new throttling code introduced bdrv_start_throttled_reqs(). This function not only kicks throttled requests but also temporarily disables throttling so requests can run. The outdated FIXME comment can be removed. Also drop the busy = true assignment since we overwrite it immediately afterwards. Reviewed-by: Alex Bligh <alex@alex.org.uk> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2013-12-06roms: build two seabios binariesGerd Hoffmann
Adding xhci support to seabios made it jump over the 128k line. Changing the bios size breaks migration, so we have to keep a 128k seabios binary for old machine types. New machine types can use a large 256k bios which should be big enougth for a while. This patch updates the seabios build process to build seabios twice, once full featured and once with xen and xhci turned off so the resulting binary is small enougth to fit into 128k.

2013-12-06roms: update seabios submodule to 31b8b4eea9d9ad58a73b22a6060d3ac1c419c26dGerd Hoffmann
Updates seabios to git master snapshot. seabios is in freeze now, update to final 1.7.4 will follow later this year. Summary of major changes: * Support for acpi table loading from qemu. * Support for the xhci host adapter. * Support for the pvscsi HBA. * Various minor bug fixes. * Lots of cleanups. Full shortlog since 1.7.3 (note that some of these changes have been cherry-picked into 1.7.3-stable): Evgeny Budilovsky (1): Add pvscsi boot support Gerd Hoffmann (27): coreboot: add cbmem console support Add CONFIG_DEBUG_COREBOOT config option apm: fix shutdown ahci: add missing check for allocation failure bochsvga: fallback to stdvga if dispi interface isn't present Add generic qemu detection Drop coreboot qemu detection Add qemu detection to csm uas: add (temporary) superspeed stopgap usb: add usb_update_pipe() usb: add xhci support fix buildversion.sh build: simplify cross builds build: create output dirs in do-kconfig build: explicitly set ROM size Add qemu_cfg_e820 function. Add support for etc/e820 fw_cfg file pci: don't reorder entries when moving to 64bit list pci: don't map usb host adapters above 4G pci: align 64bit pci regions to 1G pci: tweak + comment minimum allocations pci: log pci windows pci: map 64-bit BARs at location provided by emulator ahci: zap real mode macros ahci: remote some parentheses ahci: alloc structs in high memory add hw/serialio.c to SRC32SEG Jonathan A. Kollasch (1): vgahooks: add SM720 VGA BIOS hooks for WIN Enterprises MB-60470 Kevin O'Connor (80): Fix USB EHCI detection that was broken in hlist conversion of PCIDevices. Update README to include info on VARLOW variables. PIC code cleanups. Move internal timer code from clock.c to a new file timer.c. Don't pass khz to pmtimer_setup - it's always PM_TIMER_FREQUENCY. Add helper functions to convert timer irqs to milliseconds. Improve accuracy of internal timers. Rename cpu_khz to TimerKHz. Shift CPU TSC down to reduce need for 64bit variables. Rename check_timer() function (and similar) to irqtimer_check(). Rename check_tsc() (and similar) to timer_check() and use u32. Separate out timer setup code. Unify pmtimer_read() and pittimer_read() code. Default unused UMB areas to be read-only. Add missing mathcp_setup() call to CSM code. Fix bug in CBFS file walking with compressed files. Support custom boot menu prompt and custom boot menu key. Minor cleanups to smm assembler. Add config option to support memory allocations in 9-segment. Minor - no need to declare MaxCountCPUs as VARFSEG. Minor - simplify rom_reserve(). Rename tools/ directory to scripts/ directory. Update kconfig to latest version. build: Don't use vpath makefile directive. Move code centered around specific hardware devices to src/hw/ Move code cenetered around firmware initialization to src/fw/ build: Reorder makefile source list to group like files together. README: Update readme to note scripts/ directory rename and vgasrc/ directory. vgabios: Rename stdvga_bpp_factor to stdvga_vram_ratio. vgabios: Limit the range of the VBE number of "pages" parameter. readme: Minor - fix typo in readme.
