Grygorii Strashko e549bc702a drivers: xen: gnttab: process gnttabs in reverse order ... The Xen extends domain grant tables every time domain requests gnttab basing on gnttab idx. If idx > xen_current_max_gnttab_idx the Xen extends grant table so that idx <= xen_current_max_gnttab_idx. The growing grant tables on every hypercall is a bit costly operation and it also results in the bunch of log messages: (XEN) xen-source/xen/common/grant_table.c:1909:d0v0 Expanding d0 \ grant table from 1 to 2 frames This patch changes gnttab processing from gnttab max_idx to low_idx, so the first hypercall has the largest index, ensuring that the grant table will grow only once. It also reduces number of log messages. Signed-off-by: Grygorii Strashko <grygorii_strashko@epam.com> Signed-off-by: Dmytro Firsov <dmytro_firsov@epam.com>		2025-02-14 10:41:33 +01:00
