2013-10-09Update device tree returned by CAS hypercallqemu-slof-20131009listNikunj A Dadhania2-9/+71
Add device tree parsing code and setting properties. Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>
2013-10-09fdt: introduce fdt-initNikunj A Dadhania1-6/+13
Current fdt.fs takes device-tree start address from fdt-start, this needs to be made generic for parsing device tree at later point Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>

2013-10-04Kernel parameter passed from qemu commandline ignoredNikunj A Dadhania1-4/+4
Commit ec5c9e8b (Use root.fs on qemu as well) would set the bootargs/bootpath to null string even in case when the /chosen node exist, the /chosen and boot property were populated during fdt parsing so do not change in case its already set.

2013-10-04Allow more than one client to open net devices simultaneouslyAvik Sil4-9/+9
When multiple clients are active simultaneously, they might open network devices that is already opened by other clients. This results in failure to transfer packets since obp-tftp package is not instantiated on each open. This patch resolves it by instantiating obp-tftp on each open.

2013-10-04ci: add missing close in else conditionNikunj A Dadhania1-0/+2
The code in close for calling quiesce looks if there is stdin and checks whether is being closed. That condition was being used to call quiesce. So in case when the ihandle is not that of stdin, close-dev was missing. Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>

2013-10-04pci: fix interrupt-map for bridgesAlexey Kardashevskiy1-10/+19
The previous scheme always put 0 as a parent slot#. However it is not always the case and QEMU's PCI bridge does not support putting device at slot#0 as it claims SHPC support for hotplug. This modifies the interrups map to let the linux guest resolve XICS global interrupt number correctly.

2013-10-04usb-ohci: preserve the toggleCarry bit in EDNikunj A Dadhania1-1/+2

2013-10-04Add missing close-dev in pingAvik Sil1-0/+2
Without the close-dev successive ping command fails to get the arguments, because the net device is not instantiated as the open-count is not decremented. Signed-off-by: Avik Sil <aviksil@linux.vnet.ibm.com> Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>

2013-09-26Fix 'canon' client interfaceAvik Sil1-1/+12
As per 1275 standard, canon converts the possibly ambiguous device-specifier to a fully qualified pathname (see 6.3.2.2). It is kind of find-alias for clients. Earlier canon implementation was not complete, it was not at all returning the full path name. So grub was not getting the alias path by calling canon and it was breaking. In this patch I'm checking if the passed string is already a full path by comparing the first character with '/'. In that case I return the passed string as is. Otherwise I return the find-alias.

SCSI layer represents DIR as TRUE or FALSE, and for SLOF TRUE is -1 and FALSE is 0, convert that to proper direction when building the CBW Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>
2013-08-23Add -fno-strict-aliasing in global CFLAGSqemu-slof-20130823Nikunj A Dadhania4-4/+4
This solves the bad checksum issue in udp header. The fill_udp_checksum() function suffers from "strict aliasing" problem as it is doing quite a bit of pointer casting. Signed-off-by: Avik Sil <aviksil@linux.vnet.ibm.com> Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>

OHCI HC after using the TDs queues them back to hccaDoneHead. Until this event the TDs cannot be reused, as there might be references in the host controller still pending.

2013-08-06Use root.fs on qemu as wellBenjamin Herrenschmidt3-56/+38
We had lots of duplication of code between root.fs and fdt.fs The reason we didn't use root.fs in the first place is that it tried to create the root node and the chosen node which we already have via the fdt. Instead, modify root.fs to check for their presence and only "extend" them in that case. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2013-08-06usb-ehci: Add ehci handshakeNikunj A Dadhania2-6/+43
After removal of the QTD, the device driver needs to make sure that the host controller is really done with this QTD, and does not have any local/cached copy of this. This is achieved by employing a 3-bit handshake as explained in the echi spec 4.8.2 and Fig 4-10 Also add missing memory barrier. Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>

2013-08-06usb-ohci: suspend the controller in exit code pathNikunj A Dadhania3-29/+3
Moreover ehci already suspends the controller in the hcd_exit path. So we can remove hc-suspend from the cleanup path. Also, count mechanism is not needed anymore, as quiesce is called only once. Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>
2013-08-06usb-ohci: Add a reset when closing the OHCIBenjamin Herrenschmidt1-0/+1
Or it will continue DMA'ing which is not a good idea. On recent qemu's that add proper DMA error handling, it will get into error state. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2013-08-06usb: Use proper accessors for MMIO and separate in-memory endian swapBenjamin Herrenschmidt3-129/+131
We cannot just access MMIO like that. On KVM for example, this has to be hypercalls. On js2x, we need to use special cache-inhibited loads and stores. We have accessors in cache.h, we just need to use them. However that means that read/write_reg() are no longer suitable for in-memory byteswaps. We need to use the accessors in byteorder.h for that While at it, we also fix the code to use mb() instead of barrier() as a full memory barrier is needed to actually order things.
