patch "USB: serial: simple: Add Motorola Solutions TETRA MTP3xxx and MTP85xx" added to usb-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled USB: serial: simple: Add Motorola Solutions TETRA MTP3xxx and MTP85xx to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. >From 260e41ac4dd3e5acb90be624c03ba7f019615b75 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jer=C3=B3nimo=20Borque?= <jeronimo(a)borque.com.ar> Date: Thu, 9 Jan 2020 12:23:34 -0300 Subject: USB: serial: simple: Add Motorola Solutions TETRA MTP3xxx and MTP85xx MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add device-ids for the Motorola Solutions TETRA radios MTP3xxx series and MTP85xx series $ lsusb -vd 0cad: Bus 001 Device 009: ID 0cad:9015 Motorola CGISS TETRA PEI interface Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 0 bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x0cad Motorola CGISS idProduct 0x9015 bcdDevice 24.16 iManufacturer 1 iProduct 2 iSerial 0 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 0x0037 bNumInterfaces 2 bConfigurationValue 1 iConfiguration 3 bmAttributes 0x80 (Bus Powered) MaxPower 500mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 2 bInterfaceClass 255 Vendor Specific Class bInterfaceSubClass 0 bInterfaceProtocol 0 iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0040 1x 64 bytes bInterval 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x01 EP 1 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0040 1x 64 bytes bInterval 0 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 1 bAlternateSetting 0 bNumEndpoints 2 bInterfaceClass 255 Vendor Specific Class bInterfaceSubClass 0 bInterfaceProtocol 0 iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x82 EP 2 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0040 1x 64 bytes bInterval 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x02 EP 2 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0040 1x 64 bytes bInterval 0 Bus 001 Device 010: ID 0cad:9013 Motorola CGISS TETRA PEI interface Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.00 bDeviceClass 0 bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0x0cad Motorola CGISS idProduct 0x9013 bcdDevice 24.16 iManufacturer 1 iProduct 2 iSerial 0 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 0x0037 bNumInterfaces 2 bConfigurationValue 1 iConfiguration 3 bmAttributes 0x80 (Bus Powered) MaxPower 500mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 2 bInterfaceClass 255 Vendor Specific Class bInterfaceSubClass 0 bInterfaceProtocol 0 iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x81 EP 1 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0200 1x 512 bytes bInterval 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x01 EP 1 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0200 1x 512 bytes bInterval 0 Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 1 bAlternateSetting 0 bNumEndpoints 2 bInterfaceClass 255 Vendor Specific Class bInterfaceSubClass 0 bInterfaceProtocol 0 iInterface 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x82 EP 2 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0200 1x 512 bytes bInterval 0 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x02 EP 2 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0200 1x 512 bytes bInterval 0 Signed-off-by: Jerónimo Borque <jeronimo(a)borque.com.ar> Cc: stable <stable(a)vger.kernel.org> Signed-off-by: Johan Hovold <johan(a)kernel.org> --- drivers/usb/serial/usb-serial-simple.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/usb/serial/usb-serial-simple.c b/drivers/usb/serial/usb-serial-simple.c index edbbb13d6de6..bd23a7cb1be2 100644 --- a/drivers/usb/serial/usb-serial-simple.c +++ b/drivers/usb/serial/usb-serial-simple.c @@ -86,6 +86,8 @@ DEVICE(moto_modem, MOTO_IDS); #define MOTOROLA_TETRA_IDS() \ { USB_DEVICE(0x0cad, 0x9011) }, /* Motorola Solutions TETRA PEI */ \ { USB_DEVICE(0x0cad, 0x9012) }, /* MTP6550 */ \ + { USB_DEVICE(0x0cad, 0x9013) }, /* MTP3xxx */ \ + { USB_DEVICE(0x0cad, 0x9015) }, /* MTP85xx */ \ { USB_DEVICE(0x0cad, 0x9016) } /* TPG2200 */ DEVICE(motorola_tetra, MOTOROLA_TETRA_IDS); -- 2.25.0

[tip: x86/pti] x86/cpu: Update cached HLE state on write to TSX_CTRL_CPUID_CLEAR

This is because cpuinfo_x86->x86_capability HLE bit is not updated after TSX state is changed via the new MSR IA32_TSX_CTRL. Update the cached HLE bit also since it is expected to change after an update to CPUID_CLEAR bit in MSR IA32_TSX_CTRL.

[PATCH v2] USB: serial: quatech2: handle unbound ports

by Johan Hovold

Check for NULL port data in the modem- and line-status handlers to avoid dereferencing a NULL pointer in the unlikely case where a port device isn't bound to a driver (e.g. after an allocation failure on port probe). Note that the other (stubbed) event handlers qt2_process_xmit_empty() and qt2_process_flush() would need similar sanity checks in case they are ever implemented.

[PATCH v2] xen/balloon: Support xend-based toolstack take two

by Juergen Gross

Commit 3aa6c19d2f38be ("xen/balloon: Support xend-based toolstack") tried to fix a regression with running on rather ancient Xen versions. Unfortunately the fix was based on the assumption that xend would just use another Xenstore node, but in reality only some downstream versions of xend are doing that. The upstream xend does not write that Xenstore node at all, so the problem must be fixed in another way. The easiest way to achieve that is to fall back to the behavior before commit 96edd61dcf4436 ("xen/balloon: don't online new memory initially") in case the static memory maximum can't be read. This is achieved by setting static_max to the current number of memory pages known by the system resulting in target_diff becoming zero.

[PATCH] x86/CPU/AMD: Ensure clearing of SME/SEV features is maintained

by Tom Lendacky

If the SME and SEV features are present via CPUID, but memory encryption support is not enabled (MSR 0xC001_0010[23]), the features are cleared using clear_cpu_cap(). However, if get_cpu_cap() is later called, these features will be reset back to present, which is not desired. Change from using clear_cpu_cap() to setup_clear_cpu_cap() so that the clearing of the features is maintained.
