The former implementation called 'TRACE_AND_STOP' which led to the
'usb_host_drv' to stop whenever such a function was called. Rather
than stopping return '0' and let the contrib code deal with this
situation.
Issue #4116.
This commit backports the Linux upstream commit (d4a6106) [*]
that introduces a check to prevent the sglist from being used
unconditionally.
[*] 'xhci: fix bounce buffer usage for non-sg list case'
Fixes#4116.
* The device XML information dataspace is only provided,
when the client's policy states `info="yes"`
* The device XM information gets changed to include the
physical resource names (I/O memory and IRQ addresses)
instead of virtual ids and page offset
Fix#4077
As linux drivers may distinguish device configuration by pci subdevice id in
addition to the pci device id, the former must also be used for finding the
matching entry. Otherwise, e.g., the iwlwifi driver might load the wrong
firmware.
Side note: Add break statement to save superfluous iterations after
match was identified.
Fixes genodelabs#4076
This API rework eases the access to memory-mapped I/O registers and
interrupts when using the platform driver. It introduces the notions of
- Platform::Device - one device obtained from a platform session
- Platform::Device::Mmio - locally-mapped MMIO registers of a device
- Platform::Device::Irq - interface for receiving device interrupts
The patch touches several drivers. Some drivers would require a
significant structural change to adopt the new API (e.g., net/virtio,
dde_linux drivers, imx gpio). In these cases, the patch adds
compatibility shims meant to be temporary. In other cases (e.g., imx
i2c), the adaptation was simple enough to carry through.
Fixes#4075
This patch extends the 'Platform_session::alloc_dma_buffer' interface
with a 'Cache' argument that corresponds to the argument accepted by
'Ram_allocator::alloc', which is used by the platform driver under the
hood.
Since the x86 platform driver used to be hardwired to allocate DMA
buffers as UNCACHED, I adjusted all drivers by specifying the UNCACHED
argument. Right now, this is needed as a hint for core to steer the
allocation of I/O page tables. Once we eliminate the need for such hints
(by introducing an explicit 'Region_map::attach_dma' operation), we can
revisit the drivers individually because cached DMA buffers should
generally be fine on the x86 architecture.
Issue #2243
The commits adds the same configuration values as supported up to now by
the monolithic usb driver. In contrast to the original, by default all drivers
are started. Disabling a controller type is used by Sculpt, e.g. for OHCI if
running Sculpt inside Virtualbox.
This patch is an interim fix for using HID devices that offer a HID
interface as not the first interface. It also supplements the
interface classes as supplemental information to the USB-devices
report.
Fixes#4035
Note, OpenSSL now comes as one combined depot archive *openssl* that
replaces the former *libssl* and *libcrypto* archives. The libraries are
still separate binaries for compatibility with legacy software.
Issue #3773
* Update the 'packet_size' information with the actual length for
each isoc frame to be able to handle short reads at the client side.
* Copy the whole transfer buffer because the host controller stores
the data at the original offsets, i.e., the buffer is not densely
packed.
Fixes#4018.
When the usb_net_drv was introduced in ports/run/netperf.inc, the
netperf_lxip_usb test on x86_64/hw/pc triggered the calling of the
netif_stop_queue dummy at
contrib/<DDE_LINUX>/src/drivers/usb_net/drivers/net/usb/usbnet.c:1464. As
netif_start_queue was also a dummy and allowed to be called, we tried allowing
calls to the netif_stop_queue dummy as well which fixed the
netperf_lxip_usb test on x86_64/hw/pc.
Ref #3961
The Usb session allows for submitting packets even when the interface
in question is not yet enabled. Enabling an interface will configure
the udev members properly and is normally done implicitly during
processing of an 'ALT_SETTING' packet.
In case the interface was not enabled this leads to a page-fault in
the USB host-controller driver as 'ep' is NULL.
Fixes#3999.
* Remove SPEC declarations from mk/spec
* Remove all board-specific REQUIRE declaratiions left
* Replace [have_spec <board>] run-script declarations with have_board where necessary
* Remove addition of BOARD variable to SPECS in toplevel Makefile
* Move board-specific directories in base-hw out of specs
In order to perform a smooth transition from NIC drivers that act only as NIC
session clients to NIC drivers that act only as Uplink session clients, this
commit introduces an intermediate state in which all NIC drivers support both
modes. That said, a NIC drivers mode is now statically determined through a new
optional 'mode' attribute in the drivers <config> tag that can be set to either
'nic_server' (default value) or 'uplink_client'. Reconfiguring this attribute
at a driver doesn't have any effects. Whithout this attribute being set, all
NIC drivers will behave the same as they did before the commit. When set to
'uplink_client', however, instead of providing a Nic service, they request
an Uplink session whenever their network interface becomes "UP" and close the
session whenever their network interface becomes "DOWN".
Ref #3961
Let the NIC router provide an Uplink service besides the Nic service that it
already provided. Requests for an Uplink session towards the NIC router are
assigned to Domains using the same <policy> configuration tags that are used in
order to assign Nic session requests. The MAC addresses of Uplink session
components are _NOT_ considered during the allocation of MAC addresses for NIC
session components at the same Domain. The task of avoiding MAC address clashes
between Uplink session components and Nic session components is therefore left
to the integrator. Apart from that, Uplink session components are treated by
the NIC router like any other interface.
Ref #3961
Thise driver supports USB LTE modems for Huawais' ME906s through MBIM
and provides a traditional Nic session. The "control" interface is a
Terminal session, which can be used via libmbim/mbimcli.

added to the usb session
- allow '0' configuration within the usb session
