| * | ixgbe: Limit use of 2K buffers on architectures with 256B or larger cache linesAlexander Duyck2017-03-032-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On architectures that have a cache line size larger than 64 Bytes we start running into issues where the amount of headroom for the frame starts shrinking. The size of skb_shared_info on a system with a 64B L1 cache line size is 320. This increases to 384 with a 128B cache line, and 512 with a 256B cache line. In addition the NET_SKB_PAD value increases as well consistent with the cache line size. As a result when we get to a 256B cache line as seen on the s390 we end up 768 bytes used by padding and shared info leaving us with only 1280 bytes to use for data storage. On architectures such as this we should default to using 3K Rx buffers out of a 8K page instead of trying to do 1.5K buffers out of a 4K page. To take all of this into account I have added one small check so that we compare the max_frame to the amount of actual data we can store. This was already occurring for igb, but I had overlooked it for ixgbe as it doesn't have strict limits for 82599 once we enable jumbo frames. By adding this check we will automatically enable 3K Rx buffers as soon as the maximum frame size we can handle drops below the standard Ethernet MTU. I also went through and fixed one small typo that I found where I had left an IGB in a variable name due to a copy/paste error.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Board Data File (BDF) is loaded upon driver boot-up procedure. The right board data file is identified, among others, by device and sybsystem ids. The problem, however, can occur when the (default) board data file cannot fulfill with the vendor requirements and it is necessary to use a different board data file. To solve the issue QCA uses SMBIOS type 0xF8 to store Board Data File Name Extension to specify the extension/variant name. The driver will take the extension suffix into consideration and will load the right (non-default) board data file if necessary. If it is unnecessary to use extension board data file, please leave the SMBIOS field blank and default configuration will be used. Example: If a default board data file for a specific board is identified by a string "bus=pci,vendor=168c,device=003e,subsystem-vendor=1028, subsystem-device=0310" then the OEM specific data file, if used, could be identified by variant suffix: "bus=pci,vendor=168c,device=003e,subsystem-vendor=1028, subsystem-device=0310,variant=DE_1AB" If board data file name extension is set but board-2.bin does not contain board data file for the variant, the driver will fallback to the default board data file not to break backward compatibility. This was first applied in commit f2593cb1b291 ("ath10k: Search SMBIOS for OEM board file extension") but later reverted in commit 005c3490e9db ("Revert "ath10k: Search SMBIOS for OEM board file extension"". This patch is now otherwise the same as commit f2593cb1b291 except the regression fixed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unfortunately, the nla policy was defined to have HWSIM_ATTR_RADIO_NAME as an NLA_STRING, rather than NLA_NUL_STRING, so we can't use it as a NUL-terminated string in the kernel. Rather than break the API, kasprintf() the string to a new buffer to guarantee NUL termination.

This code produces false-positive warnings for me in an allmodconfig build: drivers/staging/fsl-mc/bus/fsl-mc-bus.c: In function 'fsl_mc_bus_probe': drivers/staging/fsl-mc/bus/fsl-mc-bus.c:645:6: error: 'mc_size_cells' may be used uninitialized in this function [-Werror=maybe-uninitialized] drivers/staging/fsl-mc/bus/fsl-mc-bus.c:682:8: error: 'mc_addr_cells' may be used uninitialized in this function [-Werror=maybe-uninitialized] drivers/staging/fsl-mc/bus/fsl-mc-bus.c:644:6: note: 'mc_addr_cells' was declared here drivers/staging/fsl-mc/bus/fsl-mc-bus.c:684:8: error: 'paddr_cells' may be used uninitialized in this function [-Werror=maybe-uninitialized] drivers/staging/fsl-mc/bus/fsl-mc-bus.c:643:6: note: 'paddr_cells' was declared here To avoid the warnings, I'm simplifying the argument handling to pass the number of valid ranges in the property as the function return code rather than passing it by reference. With this change, gcc can see that we don't evaluate the cell numbers for an missing ranges property.

Since recent firmwares also require this property, it makes sense to always require it in the driver as well. If the cache-line-size property is missing, then the driver probe should fail as no dev since the kernel and dt may be out of sync. The fix is to add a check for the return value of of_property_read_u32. Changes V2: 1. Add error message if cache-line-size is missing. 2. Simple check for non-zero return value from of_property_read_u32.

This also deals with some build warnings. * xilinx - fix some error handling paths to ensure resources are released in reverse order of being acquired.
