* xlnx-zynqmp: Add a secure prop to en/disable ARM Security ExtensionsEdgar E. Iglesias2016-06-061-0/+3
| | | | | | | | | | | | | | | Add a secure prop to en/disable ARM Security Extensions. This is particularly useful for KVM runs. Default to disabled to match the behavior of KVM. This changes the default setup from having the ARM Security Extensions to not longer having them. Signed-off-by: Edgar E.

* i2c: add aspeed i2c controllerCédric Le Goater2016-06-063-0/+457
| | | | | | | | | | | | | | | | | | | | | | | The Aspeed AST2400 integrates a set of 14 I2C/SMBus bus controllers directly connected to the APB bus. They can be programmed as master or slave but the propopsed model only supports the master mode. On the TODO list, we also have : - improve and harden the state machine. - bus recovery support (used by the Linux driver). - transfer mode state machine bits. this is not strictly necessary as it is mostly used for debug. The bus busy bit is deducted from the I2C core engine of qemu. - support of the pool buffer: 2048 bytes of internal SRAM (not used by the Linux driver).

| | | | | | | | | | | | | | | | | | | | This patch changes the 9p code to use readdir() again instead of readdir_r(), which is deprecated in glibc 2.24.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If several threads concurrently call readdir() with the same directory stream pointer, it is possible that they all get a pointer to the same dirent structure, whose content is overwritten each time readdir() is called. We must thus serialize accesses to the dirent structure. This may be achieved with a mutex like below: lock_mutex(); readdir(); // work with the dirent unlock_mutex(); This patch adds all the locking, to prepare the switch to readdir().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fifo is normal ram. So kvm vcpu threads and qemu iothread can access the fifo in parallel without syncronization.

So add shadows for them, to make sure the guest can't modify them after we've applied sanity checks.

So, we need another way to handle the underlying issue. Lets create a new pixman image, grab a reference on the pixman providing the underlying storage, hook up a destroy callback which releases the reference. That way regions work again and releasing the backing storage should still be impossible thanks to the extra reference we are holding.

This is a total of 10 bits that need to be used by the Phy chip/address decoding function. This patch fixes the number of bits used from 9 to 10.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the FEC chapter of i.MX25 reference manual When writing the MMFR register, bit 29 and 28 select the requested operation. * 10 means read operation with valid MII mgmt frame * 11 means read operation with non compliant MII mgmt frame * 01 means write operation with valid MII mgmt frame * 00 means write operation with non compliant MII mgmt frame So while bit 28 does change beween read/write for valid MII mgmt frame, the mening is inverted for non compliant MII mgmt frame. Bit 29 on the other hand means read/write whatever the type of mgmt frame involved. So this patch change the operation selection from bit 28 to bit 29 as it is more generic.

This implementation is derived from the e1000 emulation code, and utilizes the TX/RX packet abstractions that were initially developed for the vmxnet3 device. Although some parts of the introduced code may be shared with e1000, the differences are substantial enough so that the only shared resources for the two devices are the definitions in hw/net/e1000_regs.h. Similarly to vmxnet3, the new device uses virtio headers for task offloads (for backends that support virtio extensions). Usage of virtio headers may be forcibly disabled via a boolean device property "vnet" (which is enabled by default). In such case task offloads will be performed in software, in the same way it is done on backends that do not support virtio headers. The device code is split into two parts: 1. hw/net/e1000e.c: QEMU-specific code for a network device; 2. hw/net/e1000e_core.[hc]: Device emulation according to the spec. The new device name is e1000e.
