If this is not set the dma-buf attachments will be mapped for 66 every time the GPU need to access the buffer. 67 68 Mapping for each access can cause lower performance. 69 70config MALI_SHARED_INTERRUPTS 71 bool "Support for shared interrupts" 72 depends on MALI400 73 default n 74 help 75 Adds functionality required to properly support shared interrupts. Without this support, 76 the device driver will fail during insmod if it detects shared interrupts. This also 77 works when the GPU is not using shared interrupts, but might have a slight performance 78 impact. 79 80config MALI_PMU_PARALLEL_POWER_UP 81 bool "Power up Mali PMU domains in parallel" 82 depends on MALI400 83 default n 84 help 85 This makes the Mali driver power up all PMU power domains in parallel, instead of 86 powering up domains one by one, with a slight delay in between. Powering on all power 87 domains at the same time may cause peak currents higher than what some systems can handle. 88 These systems must not enable this option. 89 90config MALI_DT 91 bool "Using device tree to initialize module" 92 depends on MALI400 && OF 93 default n 94 help 95 This enable the Mali driver to choose the device tree path to get platform resoures 96 and disable the old config method. Mali driver could run on the platform which the 97 device tree is enabled in kernel and corresponding hardware description is implemented 98 properly in device DTS file. 99 100config MALI_DEVFREQ 101 bool "Using devfreq to tuning frequency" 102 depends on MALI400 && PM_DEVFREQ 103 select DEVFREQ_GOV_SIMPLE_ONDEMAND 104 default n 105 help 106 Support devfreq for Mali. 107 108 Using the devfreq framework and, by default, the simpleondemand 109 governor, the frequency of Mali will be dynamically selected from the 110 available OPPs. 111 112config MALI_QUIET 113 bool "Make Mali driver very quiet" 114 depends on MALI400 && !MALI400_DEBUG 115 default n 116 help 117 This forces the Mali driver to never print any messages. 118 119 If unsure, say N. 120
