* pci: add qemu gpex host bridge support.microvmGerd Hoffmann2020-10-151-0/+62
| | | | | | | | | | | | | | | | | | | | | | | | | Find PCIe root using ACPI DSDT table. Setup PCI bars. initialize PCI devices. Working: - finds + drives xhci-pci / virtio-pci devices. TODO / known issues: - ioport setup is broken. - bootorder needs fixing. - 64bit mmio window not supported. - irq routing not supported. - pci config access in real mode is broken (not using mmconfig). - this breaks pcibios support. - which in turn breaks vgabios. - fixable via temporary modeswitch to 32bit. - which of course adds overhead. Also: - needed in the first place for microvm? Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

* dsdt: track device hierarchyGerd Hoffmann2020-10-152-4/+16
| | | | | | | | | | | | | | | | | | | | | | | Add parent entry to acpi_device struct, set it when parsing sub-devices, restore it when done. This allows to track and check for device relationships, for example the GSIn sub-devices of PCI0. Known limitation: Establishing relationship using Scope() does not work. This also makes the parser process data after sub-devices correctly, for example find _CRS in this case: Device (PCI0) { [ ... ] Device (GSI0) [ ... ] Name (_CRS, ResourceTemplate () { ... ] } Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>.

* usb.c: Fix devices using non-primary interface descriptorMatt DeVillier2020-09-251-8/+19
| | | | | | | | | | | | | A fair number of USB devices (keyboards in particular) use an interface descriptor other than the first available, making them non-functional currently. To correct this, iterate through all available interface descriptors until one with the correct class/subclass is found, then proceed to set the configuration and setup the driver.

* smbios: avoid integer overflow when adding SMBIOS type 0 tableDaniel P. Berrangé2020-09-081-4/+10
| | | | | | | | | SeaBIOS implements the SMBIOS 2.1 entry point which is limited to a maximum length of 0xffff. If the SMBIOS data received from QEMU is large enough, then adding the type 0 table will cause integer overflow. This results in fun behaviour such as KVM crash, or hangs in SeaBIOS.

* timer: Handle decrements of PIT counterRoman Bolshakov2020-06-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | There's a fallback to PIT if TSC is not present but it doesn't work properly. It prevents boot from floppy on isapc and 486 cpu [1][2]. SeaBIOS configures PIT in Mode 2. PIT counter is decremented in the mode but timer_adjust_bits() thinks that the counter overflows and increases 32-bit tick counter on each detected "overflow". Invalid overflow detection results in 55ms time advance (1 / 18.2Hz) on each read from PIT counter. So all timers expire much faster and 5-second floppy timeout expires in 83 real microseconds (or just a bit longer). It can be fixed by making the counter recieved from PIT an increasing value so it can be passed to timer_adjust_bits(): 0, 1, 2 and up to 65535 and then the counter is re-loaded with 0. 1. https://bugs.launchpad.net/seabios/+bug/1840719 2. https://lists.gnu.org/archive/html/qemu-devel/2019-08/msg03924.html Fixes: eac11944019 ("Unify pmtimer_read() and pittimer_read() code.")

R. Silva <gustavo@embeddedor.com> from his Linux kernel commits.] The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member [1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.
