Michael Kelley 5e7d8ddf2a hv_netvsc: Calculate correct ring size when PAGE_SIZE is not 4 Kbytes ... commit 6941f67ad3 upstream. Current code in netvsc_drv_init() incorrectly assumes that PAGE_SIZE is 4 Kbytes, which is wrong on ARM64 with 16K or 64K page size. As a result, the default VMBus ring buffer size on ARM64 with 64K page size is 8 Mbytes instead of the expected 512 Kbytes. While this doesn't break anything, a typical VM with 8 vCPUs and 8 netvsc channels wastes 120 Mbytes (8 channels * 2 ring buffers/channel * 7.5 Mbytes/ring buffer). Unfortunately, the module parameter specifying the ring buffer size is in units of 4 Kbyte pages. Ideally, it should be in units that are independent of PAGE_SIZE, but backwards compatibility prevents changing that now. Fix this by having netvsc_drv_init() hardcode 4096 instead of using PAGE_SIZE when calculating the ring buffer size in bytes. Also use the VMBUS_RING_SIZE macro to ensure proper alignment when running with page size larger than 4K.
