Hello everybody on the list, I have a KNC-1 DVB-S card running under kernel 2.6.36 and mythtv. I experience high load values in top like mentioned ages ago in this thread: http://www.linuxtv.org/pipermail/linux-dvb/2008-June/026509.html. My card has no CI-Module installed and the high load was CI-Module related, so I decided to give it a try and completely disable ciintf_init() in the kernel module which helped a lot. Load decreased by 50-80%. So I decided to add a module parameter to disable ciintf_init() on demand. Here is the diff:
65,69d64 < < int budget_init_ci=1; < module_param_named(init_ci, budget_init_ci, int, 0644); < MODULE_PARM_DESC(init_ci, "Turn on(1)/off(0) ci initializing (default:on)."); < 1519,1520c1514 < if (budget_init_ci) < ciintf_init(budget_av); --- > ciintf_init(budget_av); I don't know if this is useful at all so please be patient with me. If you have comments or anything else, please do answer to my mail-address too, as I'm not subscribed to the list.
