4aa9ef8a2 Bluetooth: btusb: Only check needs_reset_resume DMI table for QCA rome chipsets ... Browse Code »

commit fc54910280eb38bde923cdf0898e74687d8e6989 upstream.

Jeremy Cline correctly points out in rhbz#1514836 that a device where the
QCA rome chipset needs the USB_QUIRK_RESET_RESUME quirk, may also ship
with a different wifi/bt chipset in some configurations.

If that is the case then we are needlessly penalizing those other chipsets
with a reset-resume quirk, typically causing 0.4W extra power use because
this disables runtime-pm.

This commit moves the DMI table check to a btusb_check_needs_reset_resume()
helper (so that we can easily also call it for other chipsets) and calls
this new helper only for QCA_ROME chipsets for now.

Commit f44cb4b19ed4 ("Bluetooth: btusb: Fix quirk for Atheros
1525/QCA6174") is causing bluetooth to no longer work for several
people, see: https://bugzilla.redhat.com/show_bug.cgi?id=1568911

So lets revert it for now and try to find another solution for
devices which need the modified quirk.

78728d84f Bluetooth: Add a new 04ca:3015 QCA_ROME device ... Browse Code »

[ Upstream commit 0a03f98b98c201191e3ba15a0e33f46d8660e1fd ]

This patch adds the 04ca:3015 (from a QCA9377 board) Bluetooth device
to the btusb blacklist and makes the kernel use the btqca module
instead of btusb. The patch is necessary because, without it the
04ca:3015 device defaults to using the btusb driver, which makes the
WIFI side of the QCA9377 board unusable (obtains 0 MBps in speedtest,
when the 04ca:3015 bluetooth is used with an audio headset).

15a4417cc Bluetooth: btusb: Fix quirk for Atheros 1525/QCA6174 ... Browse Code »

commit f44cb4b19ed40b655c2d422c9021ab2c2625adb6 upstream.

The Atheros 1525/QCA6174 BT doesn't seem working properly on the
recent kernels, as it tries to load a wrong firmware
ar3k/AthrBT_0x00000200.dfu and it fails.

This seems to have been a problem for some time, and the known
workaround is to apply BTUSB_QCA_ROM quirk instead of BTUSB_ATH3012.

The device in question is:

The issue can be reproduced before commit fd865802c66b ("Bluetooth:

resume quirk is still needed for this system.

commit f0e8c61110c2c85903b136ba070daf643a8b6842 upstream.

Commit 1fdb92697469 ("Bluetooth: btusb: Use DMI matching for QCA
reset_resume quirking"), added the Lenovo Yoga 920 to the
btusb_needs_reset_resume_table.

Testing has shown that this is a false positive and the problems where
caused by issues with the initial fix: commit fd865802c66b ("Bluetooth:
btusb: fix QCA Rome suspend/resume"), which has already been reverted.

So the QCA Rome BT in the Yoga 920 does not need a reset-resume quirk at
all and this commit removes it from the btusb_needs_reset_resume_table.

Note that after this commit the btusb_needs_reset_resume_table is now
empty. It is kept around on purpose, since this whole series of commits
started for a reason and there are actually broken platforms around,
which need to be added to it.

971039cc4 Bluetooth: btusb: Use DMI matching for QCA reset_resume quirking ... Browse Code »

commit 1fdb926974695d3dbc05a429bafa266fdd16510e upstream.

Commit 61f5acea8737 ("Bluetooth: btusb: Restore QCA Rome suspend/resume fix
with a "rewritten" version") applied the USB_QUIRK_RESET_RESUME to all QCA
USB Bluetooth modules. But it turns out that the resume problems are not
caused by the QCA Rome chipset, on most platforms it resumes fine. The
resume problems are actually a platform problem (likely the platform
cutting all power when suspended).

The USB_QUIRK_RESET_RESUME quirk also disables runtime suspend, so by
matching on usb-ids, we're causing all boards with these chips to use extra
power, to fix resume problems which only happen on some boards.

This commit fixes this by applying the quirk based on DMI matching instead
of on usb-ids, so that we match the platform and not the chipset.

Here is the /sys/kernel/debug/usb/devices for the Bluetooth module:

fed016a79 Bluetooth: btusb: Restore QCA Rome suspend/resume fix with a "rewritten" version ... Browse Code »

commit 61f5acea8737d9b717fcc22bb6679924f3c82b98 upstream.

Commit 7d06d5895c15 ("Revert "Bluetooth: btusb: fix QCA...suspend/resume"")
removed the setting of the BTUSB_RESET_RESUME quirk for QCA Rome devices,
instead favoring adding USB_QUIRK_RESET_RESUME quirks in usb/core/quirks.c.

This was done because the DIY BTUSB_RESET_RESUME reset-resume handling
has several issues (see the original commit message). An added advantage
of moving over to the USB-core reset-resume handling is that it also
disables autosuspend for these devices, which is similarly broken on these.

But there are 2 issues with this approach:
1) It leaves the broken DIY BTUSB_RESET_RESUME code in place for Realtek
devices.
2) Sofar only 2 of the 10 QCA devices known to the btusb code have been
added to usb/core/quirks.c and if we fix the Realtek case the same way
we need to add an additional 14 entries. So in essence we need to
duplicate a large part of the usb_device_id table in btusb.c in
usb/core/quirks.c and manually keep them in sync.

This commit instead restores setting a reset-resume quirk for QCA devices
in the btusb.c code, avoiding the duplicate usb_device_id table problem.

This commit avoids the problems with the original DIY BTUSB_RESET_RESUME
code by simply setting the USB_QUIRK_RESET_RESUME quirk directly on the
usb_device.

This commit also moves the BTUSB_REALTEK case over to directly setting the
USB_QUIRK_RESET_RESUME on the usb_device and removes the now unused
BTUSB_RESET_RESUME code.

2a2ee0c1f Revert "Bluetooth: btusb: fix QCA Rome suspend/resume" ... Browse Code »

commit 7d06d5895c159f64c46560dc258e553ad8670fe0 upstream.

This reverts commit fd865802c66bc451dc515ed89360f84376ce1a56.

This commit causes a regression on some QCA ROME chips. The USB device
reset happens in btusb_open(), hence firmware loading gets interrupted.

Furthermore, this commit stops working after commit
("a0085f2510e8976614ad8f766b209448b385492f Bluetooth: btusb: driver to
enable the usb-wakeup feature"). Reset-resume quirk only gets enabled in
btusb_suspend() when it's not a wakeup source.

If we really want to reset the USB device, we need to do it before
btusb_open(). Let's handle it in drivers/usb/core/quirks.c.

a0085f251 Bluetooth: btusb: driver to enable the usb-wakeup feature ... Browse Code »

BT-Controller connected as platform non-root-hub device and
usb-driver initialize such device with wakeup disabled,
Ref. usb_new_device().

At present wakeup-capability get enabled by hid-input device from usb
function driver(e.g. BT HID device) at runtime. Again some functional
driver does not set usb-wakeup capability(e.g LE HID device implement
as HID-over-GATT), and can't wakeup the host on USB.

Most of the device operation (such as mass storage) initiated from host
(except HID) and USB wakeup aligned with host resume procedure. For BT
device, usb-wakeup capability need to enable form btusc driver as a
generic solution for multiple profile use case and required for USB remote
wakeup (in-bus wakeup) while host is suspended. Also usb-wakeup feature
need to enable/disable with HCI interface up and down.

Currently we are calling usb_submit_urb directly to submit deferred tx
urbs after unanchor them.

So the usb_giveback_urb_bh would failed to unref it in usb_unanchor_urb
and cause memory leak:
unreferenced object 0xffffffc0ce0fa400 (size 256):
...
backtrace:
[] __save_stack_trace+0x48/0x6c

Put those urbs in tx_anchor to avoid the leak, and also fix the error
handling.

634fef610 networking: add and use skb_put_u8() ... Browse Code »

Joe and Bjørn suggested that it'd be nicer to not have the
cast in the fairly common case of doing
*(u8 *)skb_put(skb, 1) = c;

Add skb_put_u8() for this case, and use it across the code,
using the following spatch:

@@
expression SKB, C, S;
typedef u8;
identifier fn = {skb_put};
fresh identifier fn2 = fn ## "_u8";
@@
- *(u8 *)fn(SKB, S) = C;
+ fn2(SKB, C);

Note that due to the "S", the spatch isn't perfect, it should
have checked that S is 1, but there's also places that use a
sizeof expression like sizeof(var) or sizeof(u8) etc. Turns
out that nobody ever did something like
*(u8 *)skb_put(skb, 2) = c;

which would be wrong anyway since the second byte wouldn't be
initialized.

Make these functions (skb_put, __skb_put and pskb_put) return void *
and remove all the casts across the tree, adding a (u8 *) cast only
where the unsigned char pointer was used directly, all done with the
following spatch:

@@
expression SKB, LEN;
typedef u8;
identifier fn = { skb_put, __skb_put };
@@
- *(fn(SKB, LEN))
+ *(u8 *)fn(SKB, LEN)

@@
expression E, SKB, LEN;
identifier fn = { skb_put, __skb_put };
type T;
@@
- E = ((T *)(fn(SKB, LEN)))
+ E = fn(SKB, LEN)

which actually doesn't cover pskb_put since there are only three
users overall.

A handful of stragglers were converted manually, notably a macro in
drivers/isdn/i4l/isdn_bsdcomp.c and, oddly enough, one of the many
instances in net/bluetooth/hci_sock.c. In the former file, I also
had to fix one whitespace problem spatch introduced.

59ae1d127 networking: introduce and use skb_put_data() ... Browse Code »

A common pattern with skb_put() is to just want to memcpy()
some data into the new space, introduce skb_put_data() for
this.

An spatch similar to the one for skb_put_zero() converts many
of the places using it:

identifier p, p2;

type t, t2;

Currrently we are disabling this wake irq after receiving it. If this
happens before we finish suspend and the pm event check is disabled,
the system will continue suspending, and this irq would not work again.

We may need to abort system suspend to avoid that.

The Marvell devices may have many gpio pins, and hence for wakeup
on these out-of-band pins, the chip needs to be told which pin is
to be used for wakeup, using an hci command.

Thus, we read the pin number etc from the device tree node and send
a command to the chip.

fd913ef7c Bluetooth: btusb: Add out-of-band wakeup support ... Browse Code »

Some onboard BT chips (e.g. Marvell 8997) contain a wakeup pin that
can be connected to a gpio on the CPU side, and can be used to wakeup
the host out-of-band. This can be useful in situations where the
in-band wakeup is not possible or not preferable (e.g. the in-band
wakeup may require the USB host controller to remain active, and
hence consuming more system power during system sleep).

The oob gpio interrupt to be used for wakeup on the CPU side, is
read from the device tree node, (using standard interrupt descriptors).
A devcie tree binding document is also added for the driver. The
compatible string is in compliance with
