solaris - OracleSolaris 11.2 -- is /usr/kernel/drv/driver.conf required for PCI? -

-

i'm implementing small pci driver academic purposes, , 1 thing i'm not clear if have provide driver.conf? different materials read (including http://blog.csdn.net/hotsolaris/article/details/1763716), pci driver config file optional, in case seems pci_config_setup() successful driver.conf provided:

name="mydrv" parent="/pci@0,0/pci8086,2e11"

then do:

% add_drv -i 'pcixxxx,yy' mydrv

and adds in system no warning or error messages. assume properties of pci device can't derived automatically system, e.g. parent bus?

i appreciate if shed light on this. thanks.

if @ random selection of small files under /kernel/drv actual physical hardware, you'll see contain line

ddi_forceattach=1;

pseudo drivers have driver.conf(4) file reflects parentage in system. recommend reading manpage, goes detail what's required here.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
