seabios-convert-value-of-be16_to_cpu-to-u64-before-s.patch: be16_to_cpu(scsi_lun->lun[i]) is 16 bits and left shifting by more than 16 will have undefined behaviour. convert it to u64 before shifting. seabios-do-not-give-back-high-ram.patch: fix bug of Oracle 6 and 7 series virtual machines using the high ram returned by sebios. seabios-drop-yield-in-smp_setup.patch: Fix SeaBIOS stuck problem becuase SeaBIOS open hardware interrupt by invoking yield(). That's dangerous and unnecessary. Let's drop it, and make the processing of setup smp more security in SeaBIOS. seabios-fix-memory-leak-when-pci-check.patch: fix code memory leak when pci check failed free busses memory when pci_bios_check_devices function returns error in pci_setup() seabios-increase-the-seabios-high-mem-zone-size.patch: In terms of version and specification, under the maximum configuration specification of the number of vcpus, virtio blocks and other features, there exists bottleneck in seabios high_mem_zone, which results in the memory application failure and causes the vm to fail to start. Increase BUILD_MAX_HIGHTABLE to 512k. seabios-increase-the-seabios-minibiostable.patch: Increase the BUILD_MIN_BIOSTABLE to 4096; support 25 virtio-blk(data) + 1 virtio-scsi(sys) + 1 virtio-net Increase the BUILD_MIN_BIOSTABLE to 5120; support 18 virtio-scsi while vm starts with IDE boot disk Signed-off-by: jiangdongxu <jiangdongxu1@huawei.com>

Subject: [PATCH 4/6] seabios: drop yield() in smp_setup()
|
|
|
|
Fix SeaBIOS stuck problem becuase SeaBIOS open hardware interrupt
|
|
by invoking yield(). That's dangerous and unnecessary. Let's drop
|
|
it, and make the processing of setup smp more security in SeaBIOS.
