@@ -31,3 +31,60 @@ the IRQ mechanism is disabled). The shared memory region is always present.
 The MMRs (INTRMASK, INTRSTATUS, IVPOSITION, and DOORBELL registers) offsets at
 the MMR region, and their functions, follow the ivshmem spec, so they work
 exactly as in the ivshmem PCI device (see ./specs/ivshmem-spec.txt).
+
+
+Device Options
+--------------
+
+The required options to create an ivshmem-flat device are: (a) the UNIX
+socket where the ivshmem server is listening, usually ``/tmp/ivshmem_socket``;
+(b) the address where to map the MMRs (``x-bus-address-iomem=``) in the VM
+memory layout; and (c) the address where to map the shared memory in the VM
+memory layout (``x-bus-address-shmem=``). Both (a) and (b) depend on the VM
+being used, as the MMRs and shmem must be mapped to a region not previously
+occupied in the VM.
+
+Example:
+
+.. parsed-literal::
+
+    |qemu-system-arm| -chardev socket,path=/tmp/ivshmem_socket,id=ivshmem_flat -device ivshmem-flat,chardev=ivshmem_flat,x-irq-qompath='/machine/soc/v7m/nvic/unnamed-gpio-in[0]',x-bus-address-iomem=0x400FF000,x-bus-address-shmem=0x40100000
+
+The other option, ``x-irq-qompath=``, is not required if the user doesn't want
+the device supporting notifications.
+
+``x-irq-qompath``. Used to inform the device which IRQ input line it can attach
+to enable the notification mechanism (IRQ). The ivshmem-flat device currently
+only supports notification via vector 0. Notifications via other vectors are
+ignored. (optional)
+
+Two examples for different machines follow.
+
+Stellaris machine (``- machine lm3s6965evb``):
+
+::
+
+    x-irq-qompath=/machine/soc/v7m/nvic/unnamed-gpio-in[0]
+
+Arm mps2-an385 machine (``-machine mps2-an385``):
+
+::
+
+    x-irq-qompath=/machine/armv7m/nvic/unnamed-gpio-in[0]
+
+The available IRQ input lines on a given VM that the ivshmem-flat device can be
+attached to can be found from the QEMU monitor (Ctrl-a + c) with:
+
+(qemu) info qom-tree
+
+``x-bus-address-iomem``. Allows changing the address where the MMRs are mapped
+into the VM memory layout. (required)
+
+ ``x-bus-address-shmem``. Allows changing the address where the shared memory
+region is mapped into the VM memory layout. (required)
+
+``shmem-size``. Allows changing the size (in bytes) of shared memory region.
+Default is 4 MiB, which is the same default used by the ivshmem server, so
+usually it's not necessary to change it. The size must match the size of the
+shared memory reserverd and informed by the ivshmem server, otherwise device
+creation fails. (optional)
