[PATCH v3 0/6] add serial console support
by Gerd Hoffmann 03 Oct '17

03 Oct '17

This patch series adds serial console support to seabios. Patches 1-4 add some bits the serial console patch depends on. Patch 5 adds the actual serial console support, for both primary display mode and splitmode (running in parallel to a vga display). The recommended way to activate the serial console is "qemu -machine graphics=no". Patch 6 is just for testing convenience and will not be merged. It makes the seabios serial console a drop-in replacement for sgabios, i.e. it is possible to activate it using "qemu -device sga". Gerd Hoffmann (6): std: add cp437 to unicode map kbd: make enqueue_key public, add ascii_to_keycode romfile: add support for constant files. paravirt: serial console configuration. add serial console support [hack] ignore sgabios, enable sercon instead Makefile | 3 +- src/config.h | 1 - src/cp437.h | 1 + src/romfile.h | 2 + src/util.h | 6 + src/clock.c | 1 + src/cp437.c | 275 ++++++++++++++++++++++ src/fw/paravirt.c | 8 + src/kbd.c | 18 +- src/misc.c | 8 - src/optionroms.c | 16 +- src/post.c | 2 + src/romfile.c | 46 ++++ src/sercon.c | 673 ++++++++++++++++++++++++++++++++++++++++++++++++++++++ src/Kconfig | 5 + src/romlayout.S | 50 +++- 16 files changed, 1097 insertions(+), 18 deletions(-) create mode 100644 src/cp437.h create mode 100644 src/cp437.c create mode 100644 src/sercon.c -- 2.9.3

characters display slowly when serial is enabled and debug level >=9
by Iru Cai 01 Oct '17

01 Oct '17

Hello, I just found that when I enable serial output and set debug level >=9, characters will display very slowly. It becomes worse when the machine has serial output. I can see the characters show on screen one by one. After I see the serial output. I think handler_16 is to blame, because there are many output for it.

[PATCH 0/4] Avoid using f-segment memory for virtio
by Kevin O'Connor 27 Sep '17

27 Sep '17

This series updates the generic code so that either "low" memory or the f-segment can be used for storing drive mapping information. It also updates the virtio code to use "low" memory for its allocations. I think there is a good chance this series will, in practice, avoid running out of memory when a large number of virtio drives are available. There are other ways to tackle this problem (eg, more of the virtio storage could be moved into "high" memory), but I think this approach has the benefit of avoiding a "big bang" patch series. Comments welcome. -Kevin Kevin O'Connor (4): boot: Rename drive_g to drive disk: Don't require the 'struct drive_s' to be in the f-segment block: Rename disk_op_s->drive_gf to drive_fl virtio: Allocate drive_s storage in low memory src/block.c | 36 ++++----- src/block.h | 2 +- src/boot.c | 16 ++-- src/cdrom.c | 6 +- src/disk.c | 218 +++++++++++++++++++++++++-------------------------- src/hw/ahci.c | 4 +- src/hw/ata.c | 26 +++--- src/hw/blockcmd.c | 10 +-- src/hw/esp-scsi.c | 2 +- src/hw/floppy.c | 20 ++--- src/hw/lsi-scsi.c | 2 +- src/hw/megasas.c | 2 +- src/hw/mpt-scsi.c | 2 +- src/hw/nvme.c | 2 +- src/hw/pvscsi.c | 2 +- src/hw/ramdisk.c | 2 +- src/hw/sdcard.c | 2 +- src/hw/usb-msc.c | 4 +- src/hw/usb-uas.c | 2 +- src/hw/virtio-blk.c | 14 ++-- src/hw/virtio-ring.c | 1 - src/hw/virtio-scsi.c | 5 +- 22 files changed, 189 insertions(+), 191 deletions(-) -- 2.9.4

[PATCH 0/2] scsi: fixes and improvements to bus scan
by Paolo Bonzini 27 Sep '17

27 Sep '17

The first patch fixes a regression where many disks on a single SCSI target could prevent LUN0 from booting on another target. The second patch then exploits the new scanning algorithm to speed up the bus scan on virtio-scsi, which has a higher limit for the target than the other adaptors and therefore was slowed down the most.

I would investigate the original cause before disabling the device on other architectures, as we could be hiding a bug that's also present in x86.

Seriously speaking, the new generic PCI Express Port was restricted to x86 and arm for reasons I don't remember. Since your work has the same scope, the restriction makes sense. Please grep for CONFIG_PCIE_PORT to convince yourself and to help coding it. Thanks, Marcel > > > Appreciated, > Marcel > > -- > Aleksandr Bezzubikov

[PATCH v7 0/4] Generic PCIE-PCI Bridge
by Aleksandr Bezzubikov 20 Sep '17

20 Sep '17

This series introduces a new device - Generic PCI Express to PCI bridge, and also makes all necessary changes to enable hotplug of the bridge itself and any device into the bridge. Changes v6->v7: Change IO/MEM/PREF reservation properties type to SIZE. Changes v5->v6: 1. Fix indentation in the cap creation function (addresses Marcel's comment) 2. Simplify capability pref_mem_* fields assignment (addresses Marcel's comment) 3. Documentation fixes: - fix mutually exclusive fields definition (addresses Laszlo's comment) - fix pcie-pci-bridge usage example (addresses Marcel's comment) Changes v4->v5: 1. Change PCIE-PCI Bridge license (addresses Marcel's comment) 2. The capability layout changes (adress Laszlo' comments): - separate pref_mem into pref_mem_32 and pref_mem_64 fields (SeaBIOS side has the same changes) - accordingly change the Generic Root Port's properties 3. Do not add the capability to the root port if no valid values are provided (adresses Michael's comment) 4. Rename the capability type to 'RESOURCE_RESERVE' (addresses Marcel's comment) 5. Remove shpc_present check function (addresses Marcel's comment) 6. Fix the 4th patch message (adresses Michael's comment) 7. Patch for SHPC enabling in _OSC method has been already merged Changes v3->v4: 1. PCIE-PCI Bridge device: "msi_enable"->"msi", "shpc"->"shpc_bar", remove local_err, make "msi" property OnOffAuto, shpc_present() is still here to avoid SHPC_VMSTATE refactoring (address Marcel's comments). 2. Change QEMU PCI capability layout (SeaBIOS side has the same changes): - change reservation fields types: bus_res - uint32_t, others - uint64_t - rename 'non_pref' and 'pref' fields - interpret -1 value as 'ignore' 3. Use parent_realize in Generic PCI Express Root Port properly. 4. Fix documentation: fully replace the DMI-PCI bridge references with the new PCIE-PCI bridge, "PCIE"->"PCI Express", small mistakes and typos - address Laszlo's and Marcel's comments. 5. Rename QEMU PCI cap creation fucntion - addresses Marcel's comment. Changes v2->v3: (0). 'do_not_use' capability field flag is still _not_ in here since we haven't come to consesus on it yet. 1. Merge commits 5 (bus_reserve property creation) and 6 (property usage) together - addresses Michael's comment. 2. Add 'bus_reserve' property and QEMU PCI capability only to Generic PCIE Root Port - addresses Michael's and Marcel's comments. 3. Change 'bus_reserve' property's default value to 0 - addresses Michael's comment. 4. Rename QEMU bridge-specific PCI capability creation function - addresses Michael's comment. 5. Init the whole QEMU PCI capability with zeroes - addresses Michael's and Laszlo's comments. 6. Change QEMU PCI capability layout (SeaBIOS side has the same changes) - add 'type' field to distinguish multiple RedHat-specific capabilities - addresses Michael's comment - do not mimiс PCI Config space register layout, but use mutually exclusive differently sized fields for IO and prefetchable memory limits - addresses Laszlo's comment 7. Correct error handling in PCIE-PCI bridge realize function. 8. Replace a '2' constant with PCI_CAP_FLAGS in the capability creation function - addresses Michael's comment. 9. Remove a comment on _OSC which isn't correct anymore - address Marcel's comment. 10. Add documentation for the Generic PCIE-PCI Bridge and QEMU PCI capability - addresses Michael's comment. Changes v1->v2: 1. Enable SHPC for the bridge. 2. Enable SHPC support for the Q35 machine (ACPI stuff). 3. Introduce PCI capability to help firmware on the system init. This allows the bridge to be hotpluggable. Now it's supported only for pcie-root-port. Now it's supposed to used with SeaBIOS only, look at the SeaBIOS corresponding series "Allow RedHat PCI bridges reserve more buses than necessary during init". Aleksandr Bezzubikov (4): hw/pci: introduce pcie-pci-bridge device hw/pci: introduce bridge-only vendor-specific capability to provide some hints to firmware hw/pci: add QEMU-specific PCI capability to the Generic PCI Express Root Port docs: update documentation considering PCIE-PCI bridge docs/pcie.txt | 49 +++++----- docs/pcie_pci_bridge.txt | 114 ++++++++++++++++++++++ hw/pci-bridge/Makefile.objs | 2 +- hw/pci-bridge/gen_pcie_root_port.c | 36 +++++++ hw/pci-bridge/pcie_pci_bridge.c | 192 +++++++++++++++++++++++++++++++++++++ hw/pci/pci_bridge.c | 46 +++++++++ include/hw/pci/pci.h | 1 + include/hw/pci/pci_bridge.h | 25 +++++ include/hw/pci/pcie_port.h | 1 + 9 files changed, 442 insertions(+), 24 deletions(-) create mode 100644 docs/pcie_pci_bridge.txt create mode 100644 hw/pci-bridge/pcie_pci_bridge.c -- 2.7.4
