2018-08-29ssdt: Fix building of legacy acpi tables on current iasl compiler1.11-stableKevin O'Connor2-2/+2
Recent versions of the iasl compiler raise an error if the table id is longer than 8 characters. Older versions of iasl would silently truncate the table id to 8 characters. Change the ssdt-misc and ssdt-pcihp files to use an 8 character id - this should not directly impact the generated aml code as the table id was already being truncated - but may help those wishing to manually compile the tables. Reported by Michael Tokarev, Vivia Nikolaidou, and several others. Signed-off-by: Kevin O'Connor <kevin@koconnor.net> (cherry picked from commit 8c3f57ea1217ea0c80a72898bc35baa0e14af0e0)

2018-07-02qemu: add qemu ramfb supportGerd Hoffmann5-14/+189
Add support for qemu ramfb. This is a simple boot framebuffer device, with normal ram being used to back the framebuffer and fw_cfg being used to configure the device. Use case (on x86): boot display for vgpu devices (which neither emulate vga nor have a vgabios). Sharing fw_cfg code with seabios turned out to be difficuilt due to various dependencies the code has on infrastructure which only seabios has. So include a copy of the code here, with those dependencies removed and also stripped down because we don't need a non-dma fallback here.

Use coreboot text mode emulation to also support the qemu bochs-display device. This is a new display device supporting simple linear framebuffers, using the bochs register interface. No support for legacy vga (text modes, planar modes, cga modes, 8bpp palette modes all dropped). The bochs interface is compatible with the qemu stdvga.

2018-03-19pci: fix 'io hints' capability for RedHat PCI bridgesMarcel Apfelbaum1-9/+5
Commit ec6cb17f (pci: enable RedHat PCI bridges to reserve additional resources on PCI init) added a new vendor specific PCI capability for RedHat PCI bridges allowing them to reserve additional buses and/or IO/MEM space. When adding the IO hints PCI capability to the pcie-root-port without specifying a value for bus reservation, the subordinate bus computation is wrong and the guest kernel gets messed up. Fix it by returning to prev code if the value for bus reservation is not set. Removed also a wrong debug print "PCI: invalid QEMU resource reserve cap offset" which appears if the 'IO hints' capability is not present. Acked-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Marcel Apfelbaum <marcel@redhat.com> (cherry picked from commit 14d91c353e19b7085fdbb7b2dcc43f3355665670)
2018-03-19shadow: Don't invoke a shutdown on reboot unless in a reboot loopKevin O'Connor1-11/+16
Old versions of KVM would map the same writable copy of the BIOS at both 0x000f0000 and 0xffff0000. As a result, a reboot on these machines would result in a reboot loop. So, the code attempts to check for that situation and invoke a shutdown instead. Commit b837e68d changed the check to run prior to the first reboot. However, this broke reboots on the QEMU isapc machine type. Change the reboot loop check to only be invoked after at least one reboot has been attempted. Reported-by: Daniel P.

2017-10-14nvme: Use the Maximum Queue Entries Supported (MQES) to initialize I/O queuesFilippo Sironi1-2/+8
Use the Maximum Queue Entries Supported (MQES) to initialize I/O queues depth rather than picking a fixed number (256) which might not be supported by some NVMe controllers (the NVMe specification says that an NVMe controller may support any number between 2 to 4096). Still cap the I/O queues depth to 256 since, during my testing, SeaBIOS was running out of memory when using something higher than 256 (4096 on the NVMe controller that I've had a chance to try).

2017-10-06nvme: fix out of memory behaviorJulian Stecklina1-36/+111
If the allocation of I/O queues ran out of memory, the code would fail to detect that and happily use these queues at address zero. For me this happens for systems with more than 7 NVMe controllers.

2017-07-02ahci: Disable Native Command QueueingZeh, Werner1-1/+0
The AHCI driver currently sets the NCQ bit for every command that is issued to the SATA drive. This is not needed as there is always only one command active at a time and in turn can lead to a hanging AHCI controller (true for Marvel 88SE9170). The following patch disables the usage of NCQ completely. With this patch the Marvel AHCI controller works just fine without any issues. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

Allows the Windows 7 bootloader NTLDR to show up in VESA mode. Allows to show the Windows 7 boot logo. Allows Windows to boot in safe mode and in normal boot using VgaSave driver with resolution up to 1600x1200.

2017-06-12Revert "lsi-scsi: reset in case of a serious problem"Roman Kagan1-2/+0
This reverts commit 11277846e819b9eef3db5ac833a6a47f95f5ef15. It was originally introduced to deal with the case when REPORT_LUNS caused an error in QEMU implementation of lsi53c895a and left it in a "confused" state making further interaction impossible. However the remedy was worse than the disease: the reset was controller-wide causing all luns to reset, losing all in-flight requests; upon that all luns lit up unit_attention condition, so that any non-informational request would fail with check_condition status. As a result, the lun enumeration succeeded and I saw the respective entries in the boot menu during my testing, but the read from those luns ended with an error and booting failed, which I didn't bother to test. So this reverts to the original error handling behavior. The problem with the failing REPORT_LUNS is addressed in the preceding patch, by making it unlikely to fail.

2017-06-12blockcmd: start REPORT_LUNS with the smallest bufferRoman Kagan1-1/+3
A number of emulated SCSI devices in QEMU incorrectly return an error to REPORT_LUNS command when the size of the data returned is smaller than the allocation length passed in. To work it around, start with the smallest allocation length possible: for 1 entry. This is a slight pessimization because it would require another REPORT_LUNS iteration if the target has more than a single LUN, but this appears to have negligible impact on boot times, and makes REPORT_LUNS enumeration work for more QEMU devices (lsi53c895a, mptsas1068).
