<body>

202

203

<p>

204

You should use simple <c>CFLAGS</c> to avoid future problems with your system.

205

For example, you should use <c>CFLAGS="-march=k8 -O2 -pipe"</c> for Athlon64 or

206

Opteron and <c>CFLAGS="-march=nocona -O2 -pipe"</c> for a EM64T processor. If

207

you plan to use a 32-bit chroot, you should use <c>CFLAGS="-march=athlon-xp

208

-O2 -pipe -msse2"</c> for a AMD64 processor and for a EM64T, you should use

209

<c>CFLAGS="-march=pentium4 -O2 -pipe"</c> <e>inside the chroot</e>.

210

</p>

211

212

<note>

213

<c>-march=k8</c> is the same as <c>-march=athlon64</c> and

214

<c>-march=opteron</c>.

215

</note>

216

217

<warn>

218

You should <e>never</e> stick <c>-fPIC</c>, <c>-m32</c> or <c>-m64</c> into

219

your <c>CFLAGS</c>. They are automatically added whenever they are needed.

220

Please also note that the <c>-Os</c> flag is currently not supported.

<title>What kernel should I use for AMD64?</title>

227

<body>

228

229

<p>

230

You can use almost all kernel sources available in Portage. We recommend to use

231

<c>gentoo-sources</c> because it is a special flavor kernel designed for Gentoo

232

Linux. It contains lots of AMD64-specific patches and therefore is the only

233

flavor supported by Gentoo/AMD64. You can try <c>vanilla-sources</c> as well.

234

If you feel brave or you need extra hardware support, you can always try the

235

experimental kernel from Andrew Morton called <c>mm-sources</c>.

236

</p>

237

238

<warn>

239

You should watch out for some kernel features which are not tested well, such

240

as <c>PREEMPT</c>.

247

<body>

248

249

<p>

250

That is a difficult question to answer. In some cases, you will experience a

251

performance improvement, in other cases you will not. For everyday use, there

252

is nearly no difference between 64-bit and 32-bit. 64-bit is generally faster

253

when it comes to floating point computing which is normally the case in

254

multimedia applications and 3D rendering. This <uri

200	<title>What CFLAGS should I use for AMD64/EM64T?</title>
201	<body>
202
203	<p>
204	You should use simple <c>CFLAGS</c> to avoid future problems with your system.
205	For example, you should use <c>CFLAGS="-march=k8 -O2 -pipe"</c> for Athlon64 or
206	Opteron and <c>CFLAGS="-march=nocona -O2 -pipe"</c> for a EM64T processor. If
207	you plan to use a 32-bit chroot, you should use <c>CFLAGS="-march=athlon-xp
208	-O2 -pipe -msse2"</c> for a AMD64 processor and for a EM64T, you should use
209	<c>CFLAGS="-march=pentium4 -O2 -pipe"</c> <e>inside the chroot</e>.
210	</p>
211
212	<note>
213	<c>-march=k8</c> is the same as <c>-march=athlon64</c> and
214	<c>-march=opteron</c>.
215	</note>
216
217	<warn>
218	You should <e>never</e> stick <c>-fPIC</c>, <c>-m32</c> or <c>-m64</c> into
219	your <c>CFLAGS</c>. They are automatically added whenever they are needed.
220	Please also note that the <c>-Os</c> flag is currently not supported.

226	<title>What kernel should I use for AMD64?</title>
227	<body>
228
229	<p>
230	You can use almost all kernel sources available in Portage. We recommend to use
231	<c>gentoo-sources</c> because it is a special flavor kernel designed for Gentoo
232	Linux. It contains lots of AMD64-specific patches and therefore is the only
233	flavor supported by Gentoo/AMD64. You can try <c>vanilla-sources</c> as well.
234	If you feel brave or you need extra hardware support, you can always try the
235	experimental kernel from Andrew Morton called <c>mm-sources</c>.
236	</p>
237
238	<warn>
239	You should watch out for some kernel features which are not tested well, such
240	as <c>PREEMPT</c>.

246	<title>Will I have a performance upgrade if I use 64-bit system instead of 32-bit?</title>
247	<body>
248
249	<p>
250	That is a difficult question to answer. In some cases, you will experience a
251	performance improvement, in other cases you will not. For everyday use, there
252	is nearly no difference between 64-bit and 32-bit. 64-bit is generally faster
253	when it comes to floating point computing which is normally the case in
254	multimedia applications and 3D rendering. This <uri
